wants changes on
assessment of regulatory
fees
NAB criticizes plan to
The National Association of Broadcast- hike FCC user fees
ers (NAB) has asked the Federal CommuNAB
nications Commission (FCC) to make several important changes in the way it assesses regulatory fees for radio and TV
stations.
In comments to the FCC, NAB said that
the 1994 user fees for radio stations are
unfair. NAB cited a Congressionally -developed FCC fee schedule that charges
all radio stations in a certain class the
same regulatory fee. The FCC found that
the statute prevents it from granting radio station relief for fiscal year 1994, but
FCC relief could be granted for fiscal year
1995, said NAB.
To provide relief to radio stations, NAB
is urging the FCC to base the radio station fee structure on the same scheme
used for TV stations. The TV fee scheme
adjusts regulatory fees to reflect the size
of markets that broadcast TV stations
serve.
In additional comments to the FCC, NAB
asked regulators not to charge satellite
TV stations, which largely repeat the programming of the parent TV station, the
same regulatory fee designed to cover
the government's full cost of regulation
for a regular TV station. NAB also wants
the FCC to establish one method to determine the size of TV markets and to
develop TV regulation fees.
NAB also suggested that broadcaster
payments to the FCC be deemed timely if
they are postmarked by the due date
rather than requiring the payments to be
received by the due date.
PBS begins testing of ATV
transmission technology
In April, the Public Broadcasting Service (PBS) started ATV field tests in Cl?arlotte, NC. Testing of the advanced digital
TV technology should deliver supersharp
images and audio and will last about
three months. It involves the digital transmission technology that will be used in
the high- definition TV system developed
by the Digital HDTV Grand Alliance.
The test is expected to prove that digital signals can be received over at least
the same area that standard NTSC signals are received. The digital data test

The Clinton Administration's proposal
to help states pay for jailing illegal immigrant felons by hiking user fees for broadcasters and other FCC -regulated industries, has been called "unfair and outrageous" by the NAB.
In a letter to the Office of Management
and Budget (OMB), NAB president and
CEO Edward O. Fritts, said that although
the program may be a noble one, there is
no logical basis to connect this Justice
Department program with FCC user fees.

Due to a growing interest in digital and
random access technology, SYPHA, an
independent consulting firm in the UK,
is conducting a survey on tapeless technology for radio. The purpose of the
survey is to gauge the market response
to the technology by providing feedback from the user's point of view. The
survey coverage will range from systems for simple cart replacement, to
editing systems and systems aimed at
full automation. Survey results should
be available by September 1994. For

ADC's New lightSwitch -The "future- proof" Digital Router.
As digital formats come and go, so does a lot of expensive equipment. But while changing
formats often requires upgrading cameras, decks and other source equipment, it doesn't have
to affect your switching system.
Introducing the new LightSwitch digital router from ADC. A switching system that literally
doesn't care what format you use. By avoiding internal reclocking, the LightSwitch router is
able to switch any true digital signal, regardless of format -even ones that don't exist yet! It can
interface with either coax or fiber and features on -site matrix mapping, group takes, chop mode
and RS232/RS485 control panel interfaces.
So, regardless of what digital format the future holds -from Dl to HDTV-turn on the
LightSwitch router from ADC. For more information

Editorial
Gold medal coverage
Editors are proud of their magazines, and often quick to tell you so. We and our staffs
spend a lot of time and effort to produce each issue. For instance, the issue you are
now holding is the result of several months of intensive planning and hard work. In
fact, more work and effort are required to produce each of our NAB preview and
review issues than any three regular issues.
What's particularly satisfying is that the May issue of Broadcast Engineering magazine represents an even higher level of product excellence.
BE has always presented readers with the most comprehensive coverage of the NAB Convention. Our pre -show and
post -show issues are the largest and most sought -after
magazines of the year.
Despite our success, this year we embarked on an even
more ambitious plan. Our goal was to bring to you a more
comprehensive look at the new products on the convention
floor, and to do so from the perspective of people who live
and breathe the industry and technology like you do
fellow engineers and managers.
Starting with our regular staff of five BE editors, which by
the way, are all former broadcast engineers, we built a
veritable army of reporters. The difference is that our reporters didn't come from a journalistic (non-technical) background and they don't write for a living. Rather, the reporters we chose for our show coverage design, build and
maintain the same type of facilities you do: radio and TV
stations, post -production houses and cable networks and
head -ends. They are engineers and managers just like you.
To these 18 engineers, we added eight more trained editors and reporters to the convention to ensure our coverage
was the most complete and accurate anywhere.
Our staff visited every booth at the show, and many companies were visited more than once by different reporters.
Each reporter was assigned to write not about companies, but about specific
technologies. This allowed us, for example, to send a camera expert to each camera
manufacturer and that's all he covered. He wasn't there to cover everything the
company had to offer, just cameras. This approach was followed for more than 20
different types of technology.
The result of our commitment to you is the most in-depth, thorough and exhaustive
coverage of the NAB convention exhibits ever before available. It wasn't easy and my
staff will tell you so, but this May issue shows that it was well worth the effort.
In your hands are more than 40 pages of NAB exhibition coverage representing
hundreds of new products and services. If it was at NAB, you'll find it covered here.
For those readers who attended the show, but know they missed some booths, and
for those who didn't get to go, this issue will fill those information gaps.
So read on. You are about to enjoy the gold medal of convention reports. NAB 1994,
covered in exhaustive detail like you've never seen before.

FCC Update
freezes broadcast
application processing
FCC
By Harry C. Martin and
Andrew S. Kersting
in a recent decision of the U.S. Court of
Appeals for the D.C. Circuit, Bechtel vs.
FCC, the court invalidated the FCC's longstanding integration policy. As a result,
the FCC is temporarily suspending the
processing of applications and the hearing and settling of proceedings that involve mutually exclusive proposals for
new broadcast facilities while it re- evaluates its comparative criteria. During the
freeze, the Mass Media Bureau will not
issue cut -off lists or adopt windows for
new FM filing opportunities. Also, amendments, integration proposals or hearing
fees will not be required to be filed. The
FCC's judges and the Review Board will
continue to issue decisions only in proceedings in which consideration of the
applicants' comparative qualifications is
not necessary to resolve the case.
NRSC-2 AM compliance
reminder
After June 30, all AM stations must
comply with NRSC -2 emission limitations, as set forth in Section 73.44(b) of
the FCC rules. See April's "Re: Radio" for
more information.
Ownership reporting requirements
Commercial stations. Each licensee of a
commercial broadcast station must file
an annual ownership report on FCC Form
323 on the anniversary date that its renewal application is required to be filed.
The only exceptions are sole proprietorships and partnerships comprised entirely of individuals. Licensees owning multiple stations with different anniversary
dates are required to file only one report
per year on the anniversary date of their
choice. The reports shouldn't be more
than a year apart. In lieu of filing a new
report, licensees with a current and unamended report on file may certify the
accuracy of their current report.
Non -commercial stations. Licensees of
non-commercial stations are required to
file an ownership report on FCC Form 323E when they file their renewal application.
Licensees owning more than one nonMartin and Kersting are attorneys with Reddy, Begley & Martin,

commercial station are required to file
only one ownership report at 5 -year intervals for TV stations, and 7 -year intervals
for radio stations. Licensees are required
to file supplemental ownership reports
within 30 days after any change occurs in
the information required by a previous
report. This includes any change in organization, officers or directors, and any
transaction affecting the ownership (direct or indirect) or voting rights with respect to the licensee or permittee, or of
any stock interest.
Ownership documents. All licensees are
required to file, within 30 days of their
execution, copies of contracts relating to
the present or future ownership or control of the licensee. These documents include such papers as articles of incorporation, bylaws, partnership agreements,
and agreements concerning the ownership or voting rights of the licensee. The
documents also include:
pledge, trust and option agreements;
*proxies;
*mortgage or loan agreements containing
provisions restricting the licensee's freedom of operation, including those affecting voting rights, specifying or limiting
the amount of dividends payable, the purchase of new equipment, or the maintenance of current assets;
"management consultant agreements;
'local marketing agreements when a station brokers more than 15% of the time on
another station in the same market (both
stations must file); and
'agreements for the sale of a station or an
interest in one.
June 1 deadline to comply with FM
translator revised ownership rules
On Nov. 8, 1990, the FCC amended its FM
translator rules. An FM translator may not
be licensed to a commercial FM broadcast
station if the translator's coverage contour extends beyond the primary station's
coverage contour. The rules were also
amended to provide that commercial FM
broadcast stations may not provide financial support beyond technical assistance
to FM translators, except those translators providing service to white areas. FM
translator stations operating prior to
Broadcast Engineering May 1994
www.americanradiohistory.com
March 1, 1991, will be "grandfathered"
with respect to complying with the revised ownership and service rules for
threeyears from the effective date of March
1, 1991. After the date was changed to
June 1, 1991, the termination of the grand fathered provisions was extended until
June 1, 1994. To eliminate any confusion
about the modified effective dates, the
FCC issued a Public Notice on Feb. 25,
1994. The notice was to remind all FM
translator licensees operating prior to
June 1, 1991, that the grandfathered provisions terminate on June 1, 1994. After that
date, all FM translators must comply with
the ownership and service rules.
California AM broadcaster
fined for exceeding power limits
The FCC's San Diego office and the Mass
Media Bureau in Washington, DC, received
an anonymous complaint alleging that a
station in the San Diego area was reducing
its operating power at sunset. However, it
was increasing its power back to its permitted daytime level after the local FCC
field office closed for the day. The San
Diego office conducted an investigation
by taking field-intensity measurements on
10 different dates. The station is required
to reduce its operating power at sunset to
protect other co-channel stations at nighttime. The investigation revealed that during the night on each of the 10 dates, the
facility was operating at approximately its
authorized daytime power level. The FCC
fined the station $20,000 for these viiolations.
Date line
The deadline for filing 1994 anneal employment reports is May 31.
Annual ownership reports or cent: fications for commercial broadcast
stations in the following states must
be filed by June 1: Arizona, Idaho,
Maryland, Michigan, Nevada, New
Mexico, Ohio, Utah, Virginia, Washington, DC, West Virginia and Wyoming.

Hundt talked about application of his
three themes: 1) access, 2) reinventing
the government, and 3) economic growth.
Citing House Energy and Commerce

MPEG 2's role
MPEG 2 forms a major part of the evolving standard and is best described in
Figure 1. MPEG 2 is basically a tool kit
with a range of compression grades that
vary in performance and price.
The elements that can be called profiles (X-axis) are compared to the various
formats or levels (Y- axis). The profile refers to one of the four types of compression: simple, main, SNR scalable and high
4:2:2. A given decoder can work at its own
profile and its own or lower
level. Following the chart, a decoder with a simple profile uses
only forward motion prediction. Moving up the chart, a
main profile implies the use of
bidirectional prediction to improve picture quality (requiring two frames of storage). Of
course, operating at different
levels requires different data
rates as depicted.
It is also interesting to note
that MPEG 2 doesn't specify any
details of how the hardware or
software are implemented to
produce the stated performance levels. However, the given syntaxes do imply many
things. For instance, for any
given profile, the decoder's
throughput and memory specs
are pretty much locked in. Also,
the chart's profiles and levels
provide the data necessary to
deal with compressing, transmitting and
decompressing different types of pictures.
In the end, the optimum compression
scheme will depend on picture content
and will require a compromise between
spatial resolution, frame rate and the amount
of noticeable compression artifacts.

Departmental
motivation
Individual employee motivation
By Rick Morris
Joe has good working relationships with
his employees. This comes from the fact
that he knows what motivates each member of his staff. He has taken the time to
learn what makes his employees work.
He understands that some of his employees always want to work on the latest
project, while others want to supervise,
or others are willing to work long hours
to earn overtime. One of his engineers
just wants to put in his eight hours and go
home. In order to be an effective manager, you need to understand what individual incentives and feedback will lead to
greater productivity and job satisfaction.
Employees are individuals
Motivational factors are personal to
each employee and vary over a person's
career. For example, money, frequently
considered to be a key source of employee motivation, is not the most effective
motivator, nor the one a station wants to
use. However, there are times in an employee's career when money may be a
motivational tool.
Principally, money is important early in
an individual's career, especially in the
beginning wage steps, when there may
be high family expenses or if the station's
pay scale is driven too low. Generally,
however, a station paying market wages
will find less success with money as a
motivating factor than other motivational techniques, such as job recognition,
increased responsibility and making the
employee feel that his contributions are
valuable to the job.
Motivational factors vary from individual to individual and vary across an employee's career. An excellent manager
understands what is important to his
employees and how to create a situation
that motivates each employee to produce his best.
The "classical" theories of
individual motivators
Money as a motivating factor is generally now less effective. When an employee
accepts a job, he has already determined

University. He is a former TV manager at station network levels.

whether he can live on the salary offered.
With few exceptions, in order to hire and
retain good employees, the salary structure within a station must be competitive. Therefore, a manager must turn to
other means of motivation.
There are several different theories on
motivation, but they can be rationalized,
summarized and combined with real
world experience to give practical guidance to the engineering manager. One
classical theory involves the "needs hierarchy," which involves meeting a person's basic needs regarding food, shelter
and security. Once these are met, an individual's needs move to higher, more personality- oriented needs. Other research
has shown a similar 2 -part set of factors
involved in motivation. These include
maintenance factors, such as salary, job
security, getting along with coworkers
and work conditions. The second type
are motivational factors and include
achievement, recognition, advancement,
status, power and affiliation. All of these
motivational factors are discernible and
usable to broadcast managers. Identifying and providing satisfaction for personal goals is an overwhelming key to motivation.
Therefore, the engineering manager can
see that before proceeding to higher levels of individual motivation, a good manager must determine if there are dismotivational issues. These are structural issues, such as whether there is a good
working environment and whether the
salary is reasonable. Once these issues
are identified and met, the most effective
motivators will be those that match the
needs of the employee. In determining
the framework for individual motivation,
try to appeal to self esteem and a sense of
achievement before resorting to financial
rewards.
Individual motivation on the job
Successful motivators will lead to greater productivity and to greater job satisfaction. This, in turn, reduces employee
turnover and the costs associated with
training replacements.
So what works as individual motivational techniques? Individual recognition,

job you have is employee management.
Making an employee feel his contributions are valued and important leads to
increased satisfaction. Take the time to
give your employees feedback. Then evaluate your method of making job assignments. Do you repeatedly assign the same
work to the same people? Is there a way
you could challenge or train each employee by giving each one a job assignment that would lead to personal growth?
Growth and advancement are important
motivators.
The ability to advance is important to
satisfaction and long-term retention of
employees. Also, do you have a method
for progressively assigning more responsibility to those who want it? Can a person move up in your department? Is there
a recognizable method for a person to
gather more responsibility between promotions? Do you have a formal public
method of recognizing performance? A
well -administered employee award program can recognize and provide tangible
feedback and reward for a job well done.
The rewards can be modest, such as dinner for two or a name on a plaque. Public
recognition is the important component.
An awards program can help satisfy the
need for recognition.
Finally, are you sensitive to those who
would like overtime when offered and
those who would rather spend time with
their significant others? Some employees will desire overtime; others will be
motivated by additional time off. These
practices, appropriately applied, will lead
to increased individual motivation.

Using cellular phones
for IFB
By Philip Hejtmanek
Most TV stations have some scheme to
radiate an interruptible foldback (IFB)
communications signal to talent and technicians in the field. (An IFB signal provides program audio that is momentarily
interruptible by a control room director's verbal communications.) Getting IFB
around the service area in a wireless
manner usually involves a dedicated audio subcarrier on the station's broadcast
channel or a separate RF link on a 2 -way
radio frequency. Both of these solutions
fail, however, when the remote site is
outside of those transmissions' coverage range. In that case, a telephone backfeed can be used to get IFB to the remote
site, but only at remote sites where phone
lines are available. The remote crew may
also be inconvenienced by the inherent
tethering of a telephone IFB approach.

uses the phone at the remote site to place
a call to the station's IFB line and then
switches the coupler on and hangs up
the telephone receiver.
A 600á1/60011 audio transformer should
be used to isolate the telephone systems
from the RPU transmitter (if the RPU transmitter's line input doesn't already have
one). The audio input gain control on the
RPU transmitter allows adjustment of IFB
level to talent.
The cellular phone and the RPU transmitter use magnetic-mount mobile antennas, either of which can be extended

When using an SNG link for remote backhaul, the IFB program audio signal fed
from the station must use a mix-minus
(i.e., a mix containing all sources except
the remote feed) instead of the usual
station air signal to avoid the reporter
hearing his voice with satellite delay over
the IFB.
This versatile IFB system has been used
for several years at WBBM-TV and is considered an essential ENG tool. It is simple
and inexpensive to build, especially if
your station already has a portable RPU
transmitter. It travels well and can easily
be customized to suit the specific requirements of your station. Your reporters also will enjoy the freedom of unwired communications.

livery of data is predictable, even under
heavy usage. This characteristic lends Iself
to automation or data acquisition applications, though the speed of data through the
system is usually slower than networks using
the contention method. Contention is the

PC-based networks.
Hardware requirements

LastKevin
month, the seven layers comprisLast
ing the Open Systems Interconnection (OSI)
were described. While moving through the
OSI, the data is packetized, framed with header information and passed to the physical
layer for transmission. The physical layer
describes the physical hardware required to
attach computers to a network. As a station
engineer you will have to deal with the hardware side of networking.
Network interface card
Just as you need a modem to communicate with another computer over a telco
line, a Network Interface Card (NIC) is
required to attach a PC to a network.
in three basic ways:
I. Token passing. The computers are attached in a ring -like arrangement. A token bit is then passed to each PC. Because only one token is available, only
the PC possessing the bit can transmit.
Examples of this are token ring, ARCnet
or FDDI.
2. Contention. Any device on the network
can transmit when it wants. If two or
more transmit at the same time, each will
wait a random interval of time to retransmit. This is called carrier sense multiple
access/collision detection. Ethernet (802.3)
uses contention as an access method.
3. Polling. A file server in control of the

The NIC is typically installed in

the internal data bus. All MCs have a
unique address burned into the ROM,
which is what the network uses to
locate the NIC.

configuration, cables are connected to transceivers, which are then attached to the PC
using a multiconductor jumper.
10Base2
also known as thin ethernet
or Cheapernet, uses RG58 coaxial cable
limited to about 185m segments.
The RG58 cable is daisy-chained to each
device on the network bus, fitted with 5011

the coaxial mediums. The devices
in networks that use unshielded
twisted pair (UTP) do not connect
directly with each other, but to a
common hub in a star arrangement
(as opposed to a bus). The hub is a
multiport device that can be passive or active. Active hubs can automatically block out a port that
has failed (maybe due to a bad cable), in order to maintain proper
communications through the remainder of the system. A passive
hub is essentially a 50f1 combiner
network and requires that each port
be properly terminated at all times.
This is used with coaxial ARCnet
networks.
UTP can be purchased in several
grades, and is typically terminated
with R1-45-type modular plugs. hi larger installations, wires can be terminated on special punchdown blocks for
ease of reconfiguration.
These are some of the key elements used to assemble a network.
Many books cover the subject in
detail. Next month we'll look at the
software for dedicated and peer to-peer -type networks.

Real-time MPEG
2
decoder
By Curtis Chan
By the time you read this, a new single
gy to increase the channel efficiency of
chip (160-pin QFP), real -time MPEG 2 video decoder called the Videomax (CL9100)
will have made its debut at NAB. In addition to MPEG 1 and MPEG 2 video decoding (no host decoding required), it provides a number of additional features to
help reduce the overall system cost for
consumer applications. The chip features
a programmable architecture that allows
the designer to customize the decoder's
functionality to the application's needs.
Some of the features include:
Real-time decoding of MPEG 1 and 2 up
to CCIR 601 resolution of 720x480 at 30Hz
(NTSC) or 720x576 at 25Hz (PAL)
Supports field- and frame-encoded input bitstreams
satellite transponders, but they were not
limited to CD bandwidths and were unwilling to settle for VHS resolution. As a
result, the MPEG committee developed a
second standard (MPEG 2) designed for
broadcast applications. The MPEG 2 standard specifies 704x480 NTSC and 704x576
PAL resolutions at data rates of 4Mb /s to
8Mb/s. MPEG 2 also supports interlaced
fields, 16:9 aspect ratio, multiple video
channels in a single system stream, and
extensibility to HDTV. Also, MPEG 1 is a
subset of MPEG 2, so
any MPEG 2 decoder
will be able to decode
MPEG 1 syntax video.
Supports error detection and concealment
Supports pan and scan for 16:9 source
material
Converts 24Hz source input to video
frame rates using 3/2 pulldown (for 24Hz
to 30Hz) or 1/1 pulldown (for 24Hz to 25Hz)
Supports up to 16Mb /s sustained input
data rate and has 8 -bit host interface
Supports audio/video synchronization
using the MPEG presentation time stamp
and decode time stamp
Power consumption is less than 2W and
has a dual power supply: 5V (I/O), 3.3V
(internal circuits).

Six main

a 32-bit bus and 1MB of DRAM.
Input process -The input process transfers data from the the host interface to
the bitstream buffer. When the bitstream
buffer is full, the input process is dis-
abled or the chip can be programmed to
handle a near full buffer automatically to
prevent buffer overflow.

MPEG 1 and MPEG 2
When MPEG began the task of specifying a syntax for compressed digital video, the goal was the delivery of video on
a CD (1.416Mb/s). Aware that it was impossible to represent a CCIR 601 resolution image at such a low data rate, they
specified a one-fourth resolution image
(352x240 NTSC and 352x288 PAL) as the
standard input format (SIF). As a result,
the committee made MPEG 1 frame oriented rather than field oriented. When
decoded, the SIF resolution video expanded to fill a full TV screen, resulting in
image quality similar to VHS.
Broadcast equipment companies recognized the potential of MPEG technoloChan is presidentof Chan and Associates, a marketing and public

access can be either local or internal.
The data interface can support sustained
data rates of 16Mb/s, 25Mb /s peak rate in
serial mode and up to 40Mb /s in byte
mode for a duration of 128 bytes.
Video interface - The video interface provides horizontal and vertical interpolation
for pixel data. It reads decoded frames from
the frame buffer and performs horizontal
filtering to convert from input resolution of
352, 480, 540 and 704 pixels/line to the output
resolution of 720 pixels/line.
DRAM interface - This interface provides
support for standard DRAMs and the array

compensation vectors are used to cornpute addresses for fetching referencedata
from local DRAM. Decompressed pictures
are stored temporarily in local DRAM.
Reference pictures are also stored in the
output buffer in local DRAM for use in
subsequent decoding.
Display process - The display process
takes the decoded video pictures stored
in the local DRAM and outputs them to
the video interface. The display process
operates in either NTSC or PAL formats.

Everything you could want
from NAB show coverage and more.
report
This month's
feature coverage centers on
the 1994 NAB Convention. From audio to
video and radio to TV transmitters, everything you could imagine was at the show.
This year's exhaustive NAB coverage will
provide you with even more details than
ever before. If you attended the show, you
know the exhibit halls were humongous,
and how difficult it was to explore every booth in every nook and cranny.
Even in four days, no one person
could visit all the booths to
learn about the new products. There simply was
not enough time during the show to take
in all of the innovations on display.
BE has the solution. With an
army of technical experts
(engineers
like you), we canvassed the show to identify the hottest in technology and new
products. The combined expertise of
these engineers is contained in the fol-
lowing pages.
We begin our highlight coverage with
the 1994 Video and Audio Pick Hits. Our
panel of 20 engineers combed the halls
looking for solutions to the problems
station and post facility engineers face
daily. They have identified this year's
Pick Hits products for both video and
audio applications.
If you missed a few booths or if you
were unable to attend, read on. Beginning on page 43, you'll find that our
comprehensive coverage provides snapshot reviews of hundreds of new products unveiled at the show.
Our report begins with an overview of
the convention from the perspective of
one who's been there and seen it all. I
hope you enjoy our efforts.

Pick
Hits
BE's panel of industry experts
selects the best new products at NAB.
By Steve Epstein and Skip Pizzi,
technical editors
This year, as in those past, the BE team of seasoned technical experts
combed the NAB floor in search of new products. The judges assembled
represented the diversity of the industry. (See °Judges and Rules," p. 108.)
Many products discussed had a common theme this year: Absolute cost was
not as important as cost /performance. In addition, many of the products filled
in holes in existing product lines, offering new features or lower cost. Buyers
were given additional access to full-featured systems in several cost /performance categories.
Here are the judges' considered selections of the top new video and audio
products exhibited at NAB '94.

Hewlett- Packard: VidJet Pro
The VidJet Pro makes it possible to print video images
on HP as well as many other brands of printers. The track unit accepts composite, component or S-video, depending on input card; a future card will accept serial digital
4:2:2. A 25 -pin Centronics parallel output connects to a wide
range of printers and plotters.
Field -installable RAM can be increased to store more than
85 single-frame images in a low -resolution format, several
frames can be stored in the high -resolution mode. Frames
can be grabbed automatically based on several parameters
including time and scene changes. Printouts can vary from
thumbnail to poster size and are limited mainly by the
capabilities of the printer.

LogoMotion is a 1 -rack unit capable of storing up to 18
logos and associated linear key signals. When expanded, it can hold 72 logos and keys. It supports real -time
playback and can display animated logos of up to six
seconds. A built -in keyer allows logos to be inserted
downstream, rather than tying up switcher resources.
Logo and key information is stored uncompressed in an
EEPROM for reliable instant access. Key, transition and
repositioning information is remotely accessible and
stored in memory, eliminating periodic readjustments.
Users can quickly reprogram logos through a video
capture option, or logos can be downloaded from a PC
using free utility software.

The WVM -710 is a high-performance,
high-resolution waveform monitor and
vectorscope with real-time auto-measure capability. It is designed for use in
the operational areas of professional
video facilities. Freeing creative types
from the hassle of interpreting waveforms, the unit immediately flags any
parameter that exceeds
prepro-
grammed limits. Engineers will find the
unit simplifies measurements, and allows for simple setting of the limits
numerically through menus. Once set,
a full-screen display provides a continuous check of signal parameters. Ten bit internal resolution provides sharp,
rasterized images, as clear and accurate as conventional CRTs. The unit
can be controlled from a PC or modem,
and measurement values can be trans ferred to the PC for storage or printout.

Sony: DVW-700 digital camcorder
Last year, Digital Betacam was a Pick Hit. This year, Sony rounded out the
line with a camcorder for field acquisition in component digital. For optimum results, 10-bit digital signal processing is used in the camera section,
which uses three FIT HyperHad 1000 CCDs. The camcorder weighs a little
more than 15 pounds (7kg) and is comparable to today's current analog
camcorders.
Maximum record time
1
is 40 minutes, with up to 120 minutes of power
available from a new lithium -ion battery. A built -in tone generator allows a
1kHz tone to be recorded along with color bars.
Setup parameters can be stored on a key-sized card for use later. The card
also can be used to set up multiple cameras to the same settings. Through
DSP, many of the camera's parameters can be adjusted and fine tuned,
including gamma, knee, black -and -white shading and skin tone detail.

The newest addition to the UVW line is
the UVW -100 camcorder. Featuring three
Inline -Transfer (IT) HyperHAD CCDs,
the camera has a horizontal resolution
of 700 TV lines. Because of the low
power consumption, it will operate for
approximately 60 minutes on a single
NP -1B battery. A variable speed shutter helps capture clear pictures of fast moving objects. Sony's Clear Scan helps
to eliminate horizontal bands when
shooting computer monitors.
In addition to the on-board recorder,
a 26-pin VTR interface connector allows the user to feed composite, component or Y/C signals to an external
recorder. Both the internal and external recorders can be used simultaneously if desired.

A flexible and sensible design philosophy characterizes this high-performance
broadcast console. Standard
mainframes are available in
five sizes from 25 to 42 positions, and each allow for a wide variety of modules. Four main stereo buses are
complemented by four mix -minus and two auxiliary send buses, two mono
buses, plus four external line input returns and a stereo cue bus. Wheatstone's
bus-minus option also allows each input channel to generate its own mix -minus
output. Monitoring is provided for control room speakers, headphones and two
separate studios. Dip switches on input modules allow versatile programming
of control functions. Other available modules include a comprehensive phone
input module, an 8-station intercom, 2- machine tape recorder remote, and event
timer /meter control module. Available electronic switching eliminates the
patchbay and allows selection of each input module's source directly from the
module, with alphanumeric LED display of source name appearing above the
fader. The intuitive, uncluttered layout makes operation versatile yet simple.

is the best way to describe the
1994 NAB Convention in Las Vegas. To be
specific:
More attendees, most notably foreign
attendees.
More exhibitors, including some you
thought were out of business.
More new products, usually offering
more of something.
More computer stuff, from vendors
ranging from AutoDesk to Seagate.
More jeans (I brought mine, but had
second thoughts about wearing them to
the show. I did, however, go casual on the
last day of the show and didn't wear a tie,
which was a first.)
More representatives from Generation
X (we Baby Boomers have officially
reached middle age, you realize).
More women engineers, marketers and
managers, and fewer Barbie-type models.
More expensive food in the convention
new
center ($1.65 for a small coffee
record).
More bizarre hotels and less available
rooms for the convention. Go figure.
How does this relate to Las Vegas? Well,
one day while driving the Strip from downtown to the Luxor Hotel, I was struck by
the curious way this famous road has
evolved. As little as three years ago, Caesar's Palace stood as an international
symbol of Las Vegas opulence. Today, in
comparison to the new Luxor pyramid or
the Emerald City of the new MGM Grand
Hotel, Caesar's seems rather bland and

uninteresting. In NAB terms, it is yesterday's technology.
Despite the considerable draw of the
Strip, a record number of attendees did
manage to get to the show floor. With
record-breaking attendance of more than
70,000, people jammed the aisles and
technical sessions. The increase over last
year was into double digits. Not bad for
an industry that has been flat on its back
for the last few years.
Same old song Eddie
It is against this backdrop that Raymond Smith, chairman and CEO of Bell
Atlantic, gave the keynote speech at the
NAB opening ceremonies. The speech
was inspired, if not inspiring, and painted
an unusually rosy future for broadcasters that choose to merge onto the information highway. In contrast, the opening
ceremony remarks of Edward Fritts, president and CEO of NAB, focused on the
same, tired song heard many times before that broadcasters are great, that we
can stonewall our way to future technologies, and that lobbying Congress is
where it's at. It was, to this observer at
least, the same song, umpteenth verse.
Most of the NAB president's speech
focused on using the clout of radio and
TV stations to twist the arms of elected
representatives so they will vote for bills
that favor the interest of broadcasters.
The reasoning goes that what's good for
NAB is good for America. Here is a sample
from Fritts' speech: "When these aspiring members of Congress come to your
station, use the opportunity to get
acquainted...Tell them about the busi-
May 1994
www.americanradiohistory.com
ness of radio and television. Brief them
on our priority issues. Then, when we
need it most, you'll be in the position to
ask for the order (emphasis added)
their vote on a key piece of legislation.
And they will be hard pressed to turn you
down." Ask for the "order ?" Is anyone
else offended by this, or is it just me?
But wait, there's more. "You provide
access for local politicians and to their
constituency...For government officials
who must constantly reach the public
that acin their quest for re-election
cess through your station is invaluable."
The Fritts speech, to this observer at
least, sounded like a scene from "Mr. Smith
Goes to Washington," with NAB playing
the part of the bad guys.
Fritts ended his remarks by assuring
the audience that over-the-air broadcasting would become tomorrow's superhighway of information. "It's universal, accessible, mobile, pervasive, wireless, absoand it's
lutely free for all Americans
now." And if that wasn't enough, in a
back -handed slap at his keynote speaker,
the NAB president declared, "...I predict
that in tomorrow's race for the gold, Marconi will give Alexander Graham Bell a
real run for his money." So much for political finesse. Nice touch, Mr. Fritts.

means "...that the three principle consumer communication devices

merging into one, and as they do, so too
are the distinctions among once -separate businesses. It is clear that before this
industry transformation is through, your

pictures. This convergence will transform
the way Americans work, play and learn.
(It will transform the way each and everyone of us does business. It will
stretch the boundaries of who
we are, and what we do, and
where we're going. Most of all,
it will offer opportunities of historic proportions to those industries that can redefine themselves around an entirely new
set of customer requirements."
Smith went on to urge cooperation between broadcasters
and telephone companies as a
way to fill the information highway that will soon develop.
"Make no mistake about it
we cannot do that without you,
any more than we believe you
can do that without us...Even if
we (Bell Atlantic) were able to develop

legend Harry Carey, who was inducted
into the Broadcaster's Hall of Fame at the
convention, would describe the convention with just two words: "holy cow!"
For most equipment owners, NAB signifies the time when your gear becomes
another year older and is replaced by
something that is smaller, works better
and costs less. This show was no exception. New and enhanced products packed
the exhibit floors in the video and audio
halls, and the mostly multimedia exhibits in the Hilton Center. Last year, the
Convention marked a turning point for
the broadcast and professional audio/
video industries. After years of lean times,
it appears that the economy has finally
turned the corner.
This mood was bolstered going into the
show by an article on the front page of
the Wall Street Journal three days before
the convention began, proclaiming that
the major TV networks, once considered
dinosaurs, may in fact be at the dawning
of a new "golden age." According to the
article, "...the Big Three are hot properties again. They have proved themselves
not only viable, but thriving
contenders that can hold onto
a mass audience and their approximately $9 billion share
of the $25 billion annual TV
advertising pie." The article
included a declaration from
Laurence Tish, CBS chairman,
that free television is here to
stay.
The NAB show floor included several products related to
HDTV. Most attendees, however, appeared to be far more
concerned with the needs of
today than the needs of tomorrow's HDTV system.

Smith concluded his talk with an invitation to broadcasters to entertain new
ways of serving the public through program distribution over an information
highway. "The future belongs to open,
not closed systems...The history of technological innovation teaches us that the
most successful industries are those who
embrace the possibilities of new technologies even at the risk of cannibalizing
their existing products."
Smith cautioned broadcasters to avoid
protectionism as a way to preserve their
future. Amen.

jabs aside, one thing NAB does well
Broadcast Engineering
multimedia exhibit area was an odd combination of non -traditional broadcast
vendors and publishing companies. In its
second year, however, the exhibition grew
into what attendees expected: a first-class
showing of advanced computer -based
products.
It is an oversimplification to say that
digital products were the hit of the show.
But they were. New strides were made in
graphics and non-linear editing systems.
Perhaps the biggest splash came in the
form of non -tape video storage systems.
Several companies showed various types
of disk-based storage systems that promise, when fully developed, to challenge
the VTR for many production and on-air
broadcast applications. Prices for the
new systems ranged from sky-high (hundreds of thousands of dollars) to relatively affordable. Determining factors include,
predictably, storage time, picture quality
(influenced greatly by the rate of compression), and features (number of channels, multiple playback capability and
other factors). This technology, by the
way, is ready to go. Numerous orders
were placed for disk -based recording
systems at the convention. (For a complete rundown of the companies and
products at the show, see the NAB Highlights, which begin on page 43.)
And speaking of orders, exhibitors of all
types and sizes reported a good show in
terms of floor traffic, sales leads, and
even on-the-spot orders. Vendors and customers alike are hopeful that the '94 NAB

stereo was on the horizon.
Certain parallels can be drawn between
then and now. At this point, broadcasters
have little involvement in the numerous
advanced technologies on the horizon,
HDTV excepted. Business is basically
good, and many stations are quite happy
to conduct business as usual. It is clear,
however, that the much-ballyhooed information highway will be constructed
and that information-on-demand will be
an important component of it. If radio
and TV broadcasters fail to get into the
fast lane of emerging technologies because of design or neglect, they will eventually lose the race for viewers and listeners. Broadcasters who make the right
choices can look forward to a new golden
age. Those who make the wrong choices
face only an ice age.

A
summary of the hot new technology from NAB '94.
Compiled by the BE editors
This May issue of Broadcast Engineering magazine contains the most
comprehensive coverage of any NAB
convention ever provided. We bring
to you the most accurate, concise and
complete reporting possible. Just as
important, we wanted the coverage
to reflect the perspective of engineers
and managers like yourself. The only
real way for a magazine to provide its
readers with knowledgeable coverage is to do so with individuals who
know and understand the industry
and who are a part of it. In this case,
it meant using expert engineers and
managers who face the same problems you do on a daily basis. Because
our reporters are engineers and managers like you and also work on the
front line, it was easy for them to see
through the smoke and mirrors that
are always present at a convention.
The result is accurate reporting with
the information presented exactly the
byline of the person who researched
the technology. We are proud of our
authors and know they share our pride
in being able to bring you the most upto -date and useful show coverage ever
before assembled.

Video servers -The tapeless society?
By David Spindle
Spindle is a principal at Capricorn Associates, a
marketing and technical consulting service. Madisor. AL.
What is a video server? Typically,
there is a high -end processor or multiples thereof, such as a 486 or RISC,
that control mass data storage, such
as a RAID (redundant array of independent drives) hard drive system, or
some other sort of hard drive configuration feeding into a solid-state buff-
er with instantaneous parallel video
and audio outputs. In some cases,
there is also mass archival storage
that may be tape- or optical-based.
Internal data storage processing
schemes range from CCIR 601 digital
component on the high side, to MPEG
1, MPEG 2 or Motion JPEG on the low
side. Most systems also accommodate digital AES/EBU audio or PCM
audio. Compression techniques balance economy in data storage space and final output
signal quality.
Micropolis exhibited the
RAID disk -based AV Server
series 100, which features
two to 64 scalable, inde-
pendent random access
MPEG channels, 10GB to
240GB data capacity, and
120 hours of MPEG material available in NTSC or PAL
outputs with mono or AES
stereo audio. The series
100 also provides VCR-type
control functions and "Hot
Swap" disk drives. System
control is managed by an
Intel 486 server PC.
Channelmatic was showing its production version
of the Adcart /D digital ad insertion sys-
tem. The system also provides real -time
MPEG compression and encoding and
automatic insertion playback. The system provides full automation of scheduling, playback and trafficking.
The EMASS storage system was demonstrated in the Silicon Graphics' booth.
It is unique in that it uses digital linear
tape systems for archival storage of
multiple terabytes (1,000 gigabytes or
one million megabytes) of data that can
be summoned into a disk-based system, the Silicon Graphics Challenge in
this case, for instantaneous multiple
playout of the video datastreams. The
MPEG
compressed system's capacity
was quoted as 2,000 to 10,000 hours of
program with up to 15 simultaneous
datastreams in composite video and
stereo audio.
IBM had its fully scalable video server
system at NAB, with distributed architecture, multiple network interfaces and
interactive application features. The IBM
system addresses not only full- motion
MPEG video, but also graphics and text.
Using an RISC 6000 processor and RAID
technology, the IBM system is capable
of 250 to 400 simultaneous video
streams, with full 16-bit stereo audio on
the low end, to an almost unlimited caMay 1994

pacity on the high end.
BTS introduced the Media
Pool in a private suite. Media
Pool addresses the tapeless
storage, editing and archiving of digital video. RAID,
hot swappable drives are
used along with variable compression techniques that let
the customer choose the level of quality on a spot -by-spot
basis. System capacities are
quoted as being from 10 minutes to 100 hours of full bandwidth video. Among the Media Pool product applications are a digital VTR emulator, a digital cart machine
emulator and a time shift/
delay system.

A.F. Associates displayed major systern refinements and upgrades to the
Radamec EPO robotics system, including a new touchscreen control system.
Up to eight cameras can be controlled at
110, once from the screen, with up to 12 shots
displayed per camera. Frame -grabbed
images are used as shot icons on the
touchscreen. Another advance is the

expected to provide excellent picture quality, using 4:1:1 component
recording technology, however, compression will cause significant losses during dubbing, thus protecting
the movie studios' copyright interests. A professional version was said
to be planned for introduction sometime after mid -1995, although little was revealed

include an on-air schedule showing the
status of each event and machine resource, routerstatus and resource scheduling chart. The company also makes a
video cart machine, the DIVA Mk. II.
For station automation, Alamar introduced the MSL -4000, a LAN -based machine controller that uses a GPLY CARD
PC- platform to handle device interface.
Switchers
The new generation of component digital production switchers bears more
resemblance to digital effects units than
switchers. Most of the major switcher
vendors had something impressive to
show the crowds at NAB '94. The relative
,absence of new composite analog products from the display booths marked the
rk
trend toward digital components. Most
of the component digital switchers offered advanced keying features, layering
IIPP and time line effects storage.
Grass Valley Group had several production switchers on display including
the long-awaited composite model 3000
switcher with three mix /effects banks
and the component digital model 4000.
The real show stopper was the model
11
,
1200
component digital production
switcher, featuring a built-in setup and
configuration screen, internal floppy disk
drive, direct aux bus control, and auto
setup on the chroma-key. Serial or
parallel digital I/O are provided to
minimize the need for external converters. Proc amp controls are provided for each input to correct source
errors.
Abekas rolled out the new
ASWR8100, a compact, powerful
switcher packed with advanced features. The switcher has color correctors associated with each of its three
keyers and four background buses.
This single M/E switcher also features a graphical user interface that
displays time lines, setup adjustments
and wipe patterns, versatile keyer
functions and the mBoss border generator that performs borders, trails,
shadows and a variety of other effects.
Snell and Wilcox, a British company
best known for standards converters, entered the component digital
switcher marketplace with the introduction of the Magus, a 4 -layer digital
switcher and 3-D effects system. The
system offers 4:2:2:4 processing with
six video and four key sources, expandable to 12 video and eight key
inputs. The system is capable of four
independent layers over a background, instant switching of layer
priority and the ability to perform
two channel effects with only one
DVE
channel.
Another British import is the D8001
digital vision mixer from Vistek. This
compact component digital switcher
features 4:4:4:4 internal processing
and handles 4:3 or 16:9 signals. Both
4:2:2 and 4:4:4 inputs can be accepted
and mixed together through a variety
of optional input router configurations. The D8001 provides control of
luminance, chrominance and black
level for each input, as well as a variety
of keying and mix effects.
The digital video switcher line from
Sony ranges from the two M/E plus
PGM /PST DVS -8000 to the two M/E
DVS -6000 to the compact single M/E
DVS- 2000C. The two bigger switchers
can be purchased with either a composite or component digital processor and feature the full range of mixing
and keying capabilities. The larger DVS8000 is well- suited to live operations,
while the more compact DVS-6000
would fit into a post -production environment. Both switchers have editor
interfaces and attach easily to digital
video effects systems.
The DVS -2000C is a 16 -input component video switcher designed to work
in a compact digital post -production
environment. The user interface features an LCD display, with soft keys
and rotary encoders. The unit has dual
video keyers with an optional DSK and
chroma -keyers that allow full 4:4:4:4

Although the category of
time base correctors and
frame synchronizers may
be considered "old hat" in
today's multimedia world,
the desktop video mini-industry has spurred a second coming for these units.
Digital Processing Systems (DPS) introduced its
DPS -290, a component TBC/
transcoder /synchronizer. It
allows transcoding among
different source systems including Y/C and composite
signals. A new 3 -line adaptive comb filter maintains
full bandwidth and is used
in the frame synchronizer
section. There are many
built -in frame-related effects, such as freeze frame,
strobe and 3:2 pull -down
simulation. Red and blue
color gain controls provide
an easy way to do some
basic color-balance correction of incoming feeds. A
new low -cost frame synchronizer, the DPS -235,
shares some of the advantages of 3-line adaptive comb
filtering for Y/C and corn posite video feeds. Red and
blue color balance controls
are also included. In addition to a dedicated front control panel, remote control is
also possible via a PC. The
new RC -2001 "Master Control" brings together remote
control of many DPS devices. The unit is intended for
broadcast and other production applications and
provides RS -232 and RS -422
input and output ports.

Standards converters
Many technological similarities exist
between the conceptual design of
R frame synchronizers and TV standards
converters. The idea of writing video
Opt into memory in one TV standard rate
and reading it out at another TV standard rate just takes the basic frame
synchronizer concept and raises it to
the "nth" degree. Although it should
not be a surprise to most people in our
industry, there is no such thing as a
"perfect" standards converter, even
though advances in motion estimation, motion compensation and interiu
converter and A26 digital -to-analog (D/
A) converter are parallel component
digital (CCIR 656) converters, with 8and 10-bit serial component digital
(SMPTE 259M) inputs available optionally. Both feature integral key channels for 4:2:2:4 signal processing and
can be controlled from a single -point
remote control using the proprietary
LINC protocol. The A27 digital 525
decoder and A28 digital 525 encoder
are format converters designed to do
the tough job of converting from composite digital to component digital and
vice versa, respectively. The A28 digital 525 encoder will encode parallel
component (CCIR 656) digital video
into composite (SMPTE 244).

polation have improved dramatically.
Users should consider their program
material, market and budget when
evaluating the many products offered.
AVS Broadcast introduced two new
standards converters. The EOS is an
8-bit, 4-field, 4 -line converter supporting all world standards in and out. The
Cyrus Prime is a 10 -bit, 4- field, 4 -line
standards converter. It is upgradeable
to a motion compensation system licensed from Vistek Electronics. I/O
interfaces are provided for analog and
digital composite, as well as analog
and digital component. Chroma and
luma noise reduction and Y- channel
detail enhancement are included.
Prime Image announced its Passport 4000, a stand -alone device that
allows the NewTek video toaster to
operate in the PAL TV standard.
Vistek released a new software
upgrade to its vector VMC (vector
motion compensation). This enhancement to its proprietary algorithm is REPLY. CARD
said to improve its motion compensation capabilities.
A/D, D/A and format conversion
the migration from analog to
digital continues, analog signals have
to be converted to digital for processAs
ing, and eventually converted back to
analog. Although conversions from
the analog domain into the digital
domain have become routine, crossing the barrier from the composite to
the component realm is still not an
easy or trivial process. Although it is
easy to fall into the habit of referring
to digital video formats and transmission protocols by using videotape
formats (i.e. D-1, D -2), this is incorrect. When appropriate, SMPTE or
CCIR designations will be used.
Abekas Video Systems offered four
types of digital video conversion devices. The A25 analog-to-digital (A /D)

Leitch, Inc. offered several conversion products, the 3500AD 8-bit component D-A with parallel outputs, the
3501AD 8 -bit component A/D with serial outputs, and the 3511 10-bit cornponent A/D with four serial outputs.
The 3511 also includes a setup aid
where internally generated color bars
are "chopped" with the input signal
allowing easy comparison to a reference. It also includes an EDH inserter
(SMPTE RP 165) and can pass or blank
VITS and VITC lines. The 3500DA 10bit component D/A has parallel component inputs and two sets of analog
outputs. The 3501DA has 10-bit serial
component inputs, two sets of analog

Nobody transmits higher quality
television remotes than AT&T
ACCUNETT" Digital Television Service.
No matter what the picture, only
ACCUNET Digital Television Service
can transmit the cleanest picture
possible to over 80 locations.
Some carriers may have to relay their
signals over other's facilities. With each
"hand-off," quality can he lost, and a
dirty" picture results. The more hand -offs,
the bigger the potential loss in quality.
But with over 35,000 miles of high

codecs and switches, AT&T can always
offer 100% end -to -end contribution
quality broadcasts. So you can extend
the reach of your television services as
far as you need, and never worry about
a drop -off in the quality of your picture.
Of course, with AT&T's highly

four reclocked serial digital outputs are
provided via the 3610V1 -S card. The DAC
and the ADC feature 10-bit digital operation. The stand -alone CES -3500 serial
component to analog composite encoder converts 10 -bit 4:2:2 component digital signals to either NTSC or PAL. The
unit has a line buffer to remove any serial
jitter before encoding the signal into composite form, eliminating chroma phase
smear in the encoded output. A frame
synchronizer is available to integrate nonsynchronous datastreams into a timed
system.
The DEC 3610 composite NTSC to component digital video decoder converts
composite analog signals to any combination of serial component, parallel component or analog component, depending on the mix of output modules selected. Part of the DigiBus line, the 3610
consists of a 3611VI-A composite analog
input module, 360CFD comb filter color
decoder, and any combination of serial,
parallel or analog component output
cards, as required.
Snell and Wilcox introduced its "gearbox" line of digital devices. Among them
is the RD1ENC, a component serial digital to composite analog converter. Variations of this model offer analog component outputs and/or active serial digital
loop- through. Card edge controls are
available for EDH mode (SMPTE RP165),
horizontal blanking and VITS blanking.
Common control of many units is
provided by the proprietary "Rollcall"
protocol.
The Sony BKPF series consists of
many digital video conversion products that fit into a PFV frame. The PFVseries frames power and house up to
either four or 14 BKPF cards. The BKPF101 is a 10-bit composite A/D converter. The BKPF-101CA is similar to the
101 except that the 101CA is for component digital signals in either the
YUV or GBR mode. The BKPF -102 is a
10-bit composite D/A converter. The
BKPF-102CA is the component version
of the 102 providing one output in
either YUV or GBR mode from a serial
component digital signal. The DFX1201 digital rate converter is a standalone 2 -rack unit format converter that
converts component digital signals
into composite digital signals. The DFX
2101 digital rate converter converts
composite digital video to component
digital video. An adaptive comb filter
performs the Y/C separation, then the
sample rate is converted for component digital sample rates.
Vistek also introduced the V4228 2 -D

By Dawn Hightower,
`
senior associate editor
Now, more than ever, the shape of broadcasting is changing. Differingtechnologles and stiff competition are challengingthe industry. But do broadcasters
haveasenseofwheretheindustrystandsonspecific issues today? This was the
gist of the FCC IndustryTechnical Panel at NAB '94.
Representatives from the NAB, the FCC, the SBE and others each gave an
overview of how their organizationsview the issues facing today's broadcasters.

MAXIMUM HIGH PERFORMANCE
Leaving no stone unturned
Within the past year, NAB's agenda has focused on such issues as EBS, RF
radiation standards, proposed changes to directional antennas and FMmodulhtion, and howthey will impact radio and TV stations.
Digital audio broadcasting (DAB) and advanced television (ATV) with regard
to competition and policymaldng is another concern at the NAB.
The impact of multimedia on the industryis a recent topic of discussion. NAB1s
in the process of developing new opportunities for revenue in the form of highspeed FM subcarriers for radio and data broadcasting systems for television.

The Mass Media Bureau of the Federal Communications Commission also is
dealing with a variety of issues. All's quiet on the FM front. However, it's another
storyon the AM band. Proceedings are under way on directional antenna performance. Aninquiryisseekingwaystoimprovepredictionsandmaintenanceof AM

Another standing issue involves RFsignal radiation. The FCC is tightening the

standards becauseANSlhasadoptedatougherstandardforprotectinghumans
from the effects of RF signals. Attention needs to be paidto this issue, especially
with those stations at shared sites. The FCC doesn't want to get involved in
disputes over access to towers and facilities.
HDTV is rolling right along. The Grand Alliance completed its legwork and is
now in the process of constructing the needed equipment.
This year, after a couple of years in hiatus, the FCC will be addressing more
policyissues. Congress isentertaininganamendmenttotheCommunicationsAct
to allow broadcasters to use HDTV channels for ancillary and supplemental
services and multiprogram broadcasting. This was proposed by the FCC in
September 1992.

Hitting close to home
An issue closetoSBE's heart is that there are 30 % less jobs for engineers today
than there were five years ago. The economy, as opposed to technical reasons,
has been acritical factor. Duopoly has also played a part. Consolidation of radio
stations has resulted in the elimination of many engineering jobs. Broadcast
engineers are having to make the transition to other roles, including contract
engineering.TheSBE ispursuingmeasuresto assist engineersthrough its job line
and training and certification programs.
In the technical and regulatory environment, the SBE is workingwith regard i o
the radiation hazard rulemaking for ANSI standard docket 9362. SBEis looking
for federal pre-emption because it feels broadcasters may not be adequately
prepared to deal with RFRcompliance on astate-by-state basis as well as federal

standards.
SBE is vigorouslydefendingthe broadcast auxiliarybands. Another petition for
rulemakingwas filed by TRW, which proposed to take 1,970MHzto2,O10MHzfor
earth to space communications. No rulemaking number has been assigned to it.
However, SBEis keeping a close eye on the issue.
SBE also is interested in the EBS rulemaking. Its concern is that when the new
system is implemented that it will be practical for broadcast engineers and radio
andTVstations.
SBE also is keeping an eye on docket 93225 regarding FM peak modulation.
Efforts are ongoing in the continued effort to have an FCC commissioner hire at
least one engineeringassistant. Each commissionerhas the opportunityto have
up to three assistants, one of which has traditionally been an engineer. At this
point, there are no engineering assistants on staff.
Progression of ATV
AdoptionoftheNorthAmerican advanced TV transmission standard is moving
quickly. Fieldtests of selectedATVtransmissionequipmentwas beingconducted

1110,
Audio cable had a new and stronfocus among all the suppliers at
NAB. The recent trend toward 7551
coaxial interconnect of AES /EBU digital audio moved Canare Cable to
offer a 1V version of its BNC/XLR
adapters. The company joins Graham- Patten Systems in supporting
the digital audio users who want to
use existing analog video DAs and
routers with digital audio. The move
away from the 11051 XLR standard
isn't universal, however, especially
in Europe. Belden introduced a series of 11051 digital audio cables that
include double -shielded 1696A with
a heavy PVC outer jacket for portable
applications. Other new Belden audio products include 1800A, a foil-
shielded general- purpose package,
with 1801A being plenum- rated. A
dual, general-purpose version is
1802A, effectively two 1800A pairs in
a zip -cord-style jacket.
One of the strongest arguments for
a 7551 coaxial interconnect standard
for digital audio has been the complexity (at least as opposed to BNCs)
of terminating with XLRs. Neutrik

Individual conductors don't even have
to be stripped, let alone tinned. A
clever shell design allows the installer to decide whether the shell is
grounded by simply rotating an inner

cigarette pack-size box with an external 9V power supply. They are handy
for remotes and also compatible with
a rack-mounted version making them
effective in facilities where equipment
is spread over several
floors.
Another peek at the
future was found at the
Electronics
Kings
booth. This year Kings
showed something
new in connectors for
triax. A conversation
with Fred Della Iacono,
King's new product development boss, uncovered a low -key, strategic alliance involving
Kings, Belden and OptoDigital. The simulated camera had what
looked like a rugged
triax connector attached to it, but it

For audio and data transport, BEC
Technologies introduced the änet
series, a 2- channel version of the Very
Large Array ProLine Series. The 2channel half-rack units allow the accumulation of up to 64 channels of
audio and data on four
high -speed RS -422 data
pairs. Optional modules
include 18/20 -bit convert-
ers and remote-controlled, premium mic pre amps.
Lots of fiber optics,
but not much optical fiber
Though you could find optical fiber
at NAB, it wasn't prominently pressed
by any of the major cable suppliers.
And broadcasters haven't been big
customers. At least not directly. The
big fiber buyers are still the telephone
companies and bypass carriers.
This year there were some definite
moves toward fiber inside the facility.
It seemed Lighthouse Digital System's
fiber- optical routers were everywhere, although often under different names. The concept behind them
is simple and effective. At the input,
light is converted to an electrical signal (digital, of course) and routed without reclocking or regeneration. After
switching, it is converted back to light
and put on another fiber. Literature
states the bandwidth at up to 1.5Gb/s
per channel.
Though not intended for HDTV, a
tiny device from IRT Electronics, Ltd.
of Australia hinted at things to come.
IRT's DV-430 transmitters and receivers are intended for those awkward
distances of more than 1,000 feet and

wasn't triax going into
the connector; it was optical fiber: The
connector was bigger and more rugged than the conventional connector
because it contained an OptoDigital
Design transceiver.
The cable coming out is also radically
new. Inside is a pair of fibers, one for
the camera signal, the other for the
viewfinder backhaul. They're surrounded by a power braid, an insulator, another power braid and the outer jacket. The package is loaded with Kevlar
for strength and strain relief at either
end. Of course, identical connector
pods are needed at either end. The
digitized signals aren't subject to the
analog degradations common to triax.
Also, because the video is traveling as
light on fiber optics, the distance factor is tied not to picture quality, but
rather to power. The hefty shields carrying power support lengths up to 2km.
Also using light, but not over fiber,
was the Canobeam from Canon. This
unit can be used to either remotely
control a camera or allow a camera
operator to be in a remote location
without need of cables to
return a signal. It is bidirectional over distances
of better than one mile and
can handle up to four video channels, eight audio channels and
one intercom channel each way.
Fiber audio transport
This year's NAB saw some innovative
approaches to the needs of the audio
community. Lightwave Systems showed
the DAS-2000 package that includes
audio transmission, routing and distribution. The system accepts up to 64
analog audio inputs, digitizes them and
multiplexes them down a single optical
fiber. At the received end, there are up

Video on fiber isn't new.
There's a lot of fiber in place,
much of it put there over a 5to 10 -year period when the
need for fiber transmission of
video was grossly underestimated. Existing fibers are fully occupied and it's often prohibitively expensive to pull
more, but an answer was supplied at NAB: Put more video

analog video signals with audio subcarriers are
digitized at eight, nine or 10 bits (depending on
picture quality requirements) into 194Mb/s packets, which are then time division multiplexed onto the
1.55Gb/s datastream for transmission. When 8 -bit
Fr quantizing is used, it's possible to carry two video
signals per packet for a total of 16 signals.
Grass Valley Group's MCF series uses a 1.2Gb /s
datastream down the fiber, but takes a modular
approach to how that stream is used, as well as the
way in which systems are physically assembled.
Video is 10 -bit digitized so that-a maximum of six
channels (one per input or output module) of video
pare supported per fiber, however, audio isn't multiplexed onto the video. Instead there are separate
audio modules that support four audio channels
each. Audio inputs /outputs are analog with 18-bit
6, digitizing at 20kHz bandwidth. This approach makes
it possible to juggle the number of video and audio
channels for optimum use.
Although today's baseband fiber -optics transmission systems provide excellent picture quality,
they don't fit well in an earth station environment.
On the receive side, there may be extra down and
up conversions and, on the transmit side, a baseband system moves encoders to the uplink site.
Ortel Corporation has come up with a solution it
calls "Microwaves on Fiber" and the Ortel product
line is called Light Links. It carries the entire transmit or receive bands for Ku, C or L band over one
single mode fiber. At the downlink, the LNA is
coupled to Ortel's fiber transmitter, and the signal
is carried up to 40km (65km for 70 /140MHz links) to
'a receiver where it's fed to the downconverter. In
the uplink situation, the user's encod- AREPLY CARD
ers remain on the premises, and the
signal is delivered to the teleport in the
Rcorrect format for simple upconversion.

Digital video on fiber
When talking about coaxial cable, component
serial digital video is discussed. When talking about
fiber, everything switches to analog composite video (at least at the inputs and outputs of the various
fiber systems). At the AT &T booth, the OmniMedia
Network display not only demonstrated routing of
digital video over fiber from within the exhibit hall,
but also from Canada and Los Angeles over AT &T's
switched 45Mb /s service called Accunet.
The Los Angeles signal originated from a component digital VTR whose parallel digital video output
and analog stereo audio outputs fed an Alcatel
Codee. The 4:2:2 video was serialized and corn pressed to approximately 42Mb /s without encoding into composite form. The stereo audio was
compressed into a Ti package that was then combined with the compressed video into a single 45Mb /s
DS3 channel easily handled by existing networks.
At the Las Vegas Convention Center end, the video
and audio were decompressed, the audio converted back to analog, and the video restored to the
original 4:2:2 parallel form. The effect was impressive giving credence to AT &T's claim of 45Mb /s
switched network service being adequate to com-
ponent post-production applications.
Another company providing terrestrial transport
on fiber is Vyvx. The company provides multipointto-multipoint distribution, and the service is rapidly
replacing many satellite links due to the
RF,PL\' CARD
high quality available. In addition, the
associatnormal time -delay problems
ed with satellite links are avoided.

HDTV at NAB '94,
By
John C. Kean
Kean is senior engineer for Mollet, Larson and Johnson, Inc., Falls Church, VA.
HDTV transmission is being seen as part of the future broadband digital dhta
network, capable of delivering a variety of services to the end user.
Flexibility of the digital medium is producing a new telecommunications indlstry. Digital video, and with it, digital transmission, isameans to offer new services
and a chance to raise new revenues against the high costs of constructing a new
digital TV facility. Specifically, broadcasters are looking at ways to use their
spectrum for future multimedia and interactive services, particularly the new
channels to be awarded for HDTV services.
HDTV:
state-of- the-art
Selection of Zenith's 8-VSB over General Instrument's QAM by the Grand
Alliance gave transmitter manufacturers little time to prepare demonstrationsior
the NAB show. PESA-MCI displayed "the first 8-VSB transmitter." The company
scrambled in the four weeks prior to the show to produce a working 1kW111F
solid -state transmitter, which was running a32Mb stream of random data.
Lurking as a new contender for HDTV transmission is COFDM . This system
received considerable attention recently in Europe as a possible modulation
mode. It also was the subject of atechnical session of three papers titled " Digtal
Modulation for Television Broadcasting" during the conference. A task force
from the TransmissionExpertGroupof the FCC Advisory Committee suggested
thatCOFDM' sclaimedstrongtoleranceofmultipath deserves furtherstudyin he
United States.
Across the exhibit hall, Dolby Laboratories highlighted the company's
support for delivering high-quality digitalaudio to complementmulticasting as
well as HDTV audio. Dolby's AC-3 was chosen by the Grand Alliance as the HDTV
audio format. AC-3 allows storage or transmission of multiple audio channels in
significantly less space than is required for uncompressed audio, sucF as
compact disk media.
Please stay tunedA new EBS system is coming
By Deanna Rood, associate editor
For the past several years, the FCC has been evaluating the current Emergency
BroadcastingSystem( EBS)which has been in useformore than 40years. In the near
future, the commission will vote on anew system. During this year's NAB, Richard
Smith, FCC chief of field operations inWashington,DC, gave somehighlights on what
is to come.
The best news about the new EBS system is that the22-second, loud, over- the-air,
test will become a part of history. Not only does the current weekly test take up
valuable air time, but the public has become so desensitized to the signal that it no
longer serves its purpose. Testinghas been conducted on more than 30 devices that
have the ability to turn on and off consumer alerting equipment, such as personal
pagers, VCRs, car radios, cable TV sets, and evensmoke detectors that can provide
the initial alert for an EBS warning. Other considerations for the new system include
modes of alerting everyone including the hearing impaired, the blind and the nonEnglish speakingpopulation.
The new system wi Il ensure compatibility among all technologies so that cable
television will serve as an equal partner in alerting the public. In the past, cabledid
not always run th a EBS message, and when it did air, it was often a rebroadcast ofthe
local signal at a later time.
Advances in technology have made possible major improvements that will result
in a morecosteffectivesystem. Withtheuseofautomation ,thesystemwill no longer
have to be activated manually. Not onlywill this reduce the ineffectiveness associ-
ated with the current system, but it will also eliminate the operator training
presentlyrequired.Stations will be able to decide who to monitor, thus reducingthe
dependencyonthedaisychain system.
The economic impact of the new system may not be as bad as some might think
according to Darryl Parker, director of marketing at TFT, Inc. TFT surveyed more
than 50 stations and determined that the median operating cost for the present, 2tone EBS system was $5,410 per station peryear. These costs came from four main
sources: 1) loss of air time, 2) record keeping, 3) repair and maintenance, and 4)
training of personnel on how to handle EBS tests in addition to real emergencies.
Using a new system that would operate automaticallywith less operator intervention, TFT estimated the median operating cost at $131 -asavings of more than$5,200
per year per station. The added cost of hardware will depend on the FCC's requirements.
With the ever-changing technology in the industry, flexibility for individual systems to be upgraded is another strongconcern.
Thecommission'sgoalis to provideoptions tothe industryand the public thatwill
create a flexible architecture capable of accommodating current and future technologies. Field tests have been conducted and the commissionwill be presenting
afinal report and order for establishing a new EBS system.

Editing and desktop systems
By David Leathers
Leathers is president of Eye Square. Carlsbad. CA.
Editing systems
At NAB '94, systems began
to cross
over the lines between linear and nonlinear. Many systems exhibited hybrid
configurations that allow the unit to function as either linear or non -linear. Because of this, the majority of editing
systems are grouped together.
BTS showed its new offerings in the
desktop editing arena, the Windows based Rio Bravo editing system and Rio
Quatro compact A /B/C roll edit controller. BCD Associates showed its new video DataBase editing system that controls four VCRs from a single PC serial
port. For those who have used Calaway
before or are presently using one, a few
new features are now offered, including a
multiple VTR "gang" feature for running
several machines together in sync. A
"look- ahead" pre -cue function for autoassembles combined with a cluster function allows only a specific block of edits
to be auto-assembled. Another feature
that is unique is individualized preroll
times for each machine.
Not to be outdone by the many companies offering new PC- or MAC -based edit-
ing systems, CMX introduced the
Gemini, named because it works as a
traditional keyboard-type editing system or it is switchable to a time -line
display clip editor. The system uses a
Silicon Graphics platform, talks to
more than 200 different devices and
hooks into ethernet for networking.
Media 100 Version 2.0, from Data
Translation, debuted at NAB '94. Its
all -on-one mastering provides higher-capacity editing and mastering on
one system, integrating character generation, digital effects and multitrack
audio mixing.
The Ensemble Pro editing systems
were shown by Editing Technologies
Corporation (ETC). With the exception of the Ensemble Pro 2, these
systems offer A/B roll editing with
GPIs and serial switcher interface on
a user-supplied IBM -compatible AT
computer.
Fast Electronics has developed two
new software options for the Video
Machine. One converts the Video Machine into a live broadcast switcher
so the system can be used in a production environment when it's not
being used for editing. The other
new option allows the use of the
Inscriber/CG in the Video Machine,
allowing greater capabilities in
graphics and text.
Grass Valley has put the Sabre 4100
lüillsted°
on an SGI/UNIX platform, getting away
from the typical proprietary programs.
It can be used with a keyboard or
mouse, has graphical displays,and
outputs standard EDLs.
The new VideoCube for NTSC and
PAL was introduced by ImMix. New
features include variable -speed playback of clips with infinitely selectable
slow and fast motion, freeze -frame in
and out for clips and multiclip move
for blocks of clips.
Matrox introduced its cuts only nonlinear system that fits into the existing
Matrox linear system. The system has
been extensively redesigned based on
input from users and Matrox now
assembles and sells the systems. The
high -end system includes three channels of 3-D digital video effects and
the non -linear program. A full nonlinear system with wipes, dissolves
and effects is expected by the end of
the year.
NewTek, the makers of the Video
Toaster, introduced the Toaster Flyer,
an A/B roll system that purports D-2
image quality using a proprietary compression scheme called Video Toaster
Adaptive Statistical Coding or VTASC.
The Flyer works in conjunction with
the Video Toaster in an Amiga 4000
and at least two fast SCSI -2 hard drives.

As was mentioned above, the lines
between what is and what isn't desktop are blurring. Because of this many
products that might be considered
desktop products may not be found
in this section, having already been
covered elsewhere. Some products,
however, are unique and are covered
here.
At the Accom booth, the company
demonstrated the new Axial WSE Work
Station Editor for SGI systems. The
WSE was shown with Accom's popular Work Station Disk. The Work Station Editor allows use of paint, graphics, animation and compositing systems running on SGI platforms to perform on-line editing tasks. Using live
video display windows and a graphical interface with clip library, operators can easily create industry -standard EDLs.
The Personal Animation Recorder
from DPS is now available for the PC.
It permits recording and real -time playback of full -color computer animation
sequences directly from a hard drive.
Compact UHF wireless...
...by the best in the business.
The new 195 Series introduces a transparent
audio quality that has never been available
from any wireless manufacturer, in studio or
field production wireless systems.
We urge you to directly compare this new
UHF system with any other wireless system,
compact or full size, at any price, from any
manufacturer. Compare RF selectivity and
rejection, operating range or thermal
stability. Compare overall audio quality.
When you do, be prepared to experience
something clearly superior to what you have
been using.

A revolutionary
dual -band compandor
system eliminates pumping and breathing
and keeps envelope distortion at incredibly
low levels.
Wide deviation ( ±75kHz) with the dual -band
compandor eliminates the need for conven-
tional pre -emphasis/de- emphasis, producing
a wide, perfectly flat frequency response.
Surface mount technology is integrated with
precision mechanical assemblies to keep the
overall size to a minimum. This preserves the
overall ruggedness which is our hallmark.
This is a wireless system that doesn't sound
like a wireless system. Isn't that what you'd
expect from the best in the business?

By Stephen K. Bramham
Bramham is engineering manager for CNN Radio, Atlanta.
Prophet Systems displayed
its Wiz-
ard for Windows, a complete net worked digital automation system. Two
1.3GB SCSI hard drives in a mirrored
configuration provide up to 425 min utes of Dolby AC -2 audio. A real -time
digital editor workstation provides one
play/record and three playback channels into an external mixing console.
All operations, including sales,

on-air talent, are combined in a
single integrated system. Sys tem size can range from two to
pokmore than 15 workstations. Automatic recording, an 8-input
switcher and a 4- stereo-track
waveform editor/mixer are also
included, along with automation control of internal hard
'drive audio and external devices.
Celebrating its 25th year in
operation,
00.
demonstrated the
most recent enhancements to the popular DAD486x digital audio delivery system. The cut -and-paste assembly editor has been revised and multicut montage capabilities have been added. Liveassist automated program operation
and digital I/O are now available, as well
as Dolby AC -2 and ISO /MPEG Layer II
data reduction. Multiple workstations
can share files via Novell NetWare 3.12
and user interface is either through the
computer keyboard, mouse or optional touchscreen.
International
Tapetronics Corporation (ITC)
continues to develop its DigiOkCenter line, splitting the system
apart into modules that can operate independently. The DigiCenter CD-25 is a new combination of software, CD controller,
DJ module and a rack. The DigiCenter Lite is an entry-level systern that allows low-cost operation with all the advantages of
DigiCenter. The DigiCenter 33182 is a combination specifically designed for AM /FM opera, tion. The LN -220 DigiCenter
Plus adds expanded networking capability so each user can
simultaneously control three
workstations. The NW-416 DigiCenter
News gives a newsroom the ability to
manage text as well as audio for the alldigital newsroom. The DigiCenter Editor is a multitrack waveform editing
option for the DigiCenter workstations.
Arrakis moved its approach clearly
toward integration of live and live-assist applications. Several new modules
were offered for interfacing Arrakis's
traditional audio consoles to its Dig ilink and new Gemini line of audio management/automation systems. Gemini
allows integration of newswires, transmitter remote control and administrative /traffic functions, and it also offers
,its own series of modular mixing console/control surfaces that incorporate
workstation, automation and live onconsole operations. New Smart 00. air
phone products add telephone interface and control to the digital audio
management system using the GAP2
protocol developed by Arrakis and

DCS and DCS Live from Computer
Concepts are aimed primarily at the
satellite and live-assist formats with
emphasis on traffic management. A
central audio storage file server and
distributed databases on a single systern allows for quick file access and
rapid updates. One central server will
support up to 16 DCS machines for a
total of 48 discrete stereo audio channels. AES /EBU options provide multiple sampling rates. An optional RAID
array provides additional redundancy.
The Windows -based system offers control via touchscreen or mouse. Each DJ
can customize a setup, and up to 18
loaded cart machines can be instantly
available.
Register Data Systems (RDS) presented the Phantom automation system. It
supports several data -reduction algorithms (including Dolby AC -2), simultaneous playback and editing, an integrated switcher /mixer (handling 14 or
Broadcast Engineering May 1994

more inputs) and comprehensive backup capabilities. The system integrates
fully with the highly developed RDS
line of traffic/billing software or other
systems, allowing long walk -away
times.
The Italian manufacturer AEV
showed two radio automation products, Aurad System 2 and Digital Jingle. The first is a modular device controller capable of operating, switching and mixing up to 64 sound sources
ranging from analog tape recorders to
hard disk systems. Satellite, remote
control and multiple -output operations are also possible. Digital
Jingle is a hard disk audio storage system that allows live or
automated playback of up to 15
hours of audio. The system
can be networked or accessed
by an outboard controller.
Sierra Automated Systems
and Engineering presented the
SAS 32000 audio switching and
mixing system, with its wide
variety of routing/distribution,
intercom, mix-minus, IFB and
teleconferencing options. The
system allows versatile control via direct serial port, interface to automation or other
user configurations. The company's DAS 9600 digitally controlled audio system offers programmable and remote level
control. The DCA-8 digitally
controlled amplifier contains
eight independent channels,
each with 128dB level range.
A cross between digital cart
machine and computer hard
disk categories is the new DDS
from Radio Systems. Based on
a 486 CPU, the DDS operates
under UNIX and uses multiple
control terminals that look and
act like cart machines. A separate audio output corresponding to
each controller is fed from the system
mainframe to conventional audio console inputs. Buttons on each control
surface provide playback control and
flexible sorting of audio cuts, with cut
title and timing data viewed on an LCD
display. Up to 16 stereo channels can
be played back simultaneously, and
external devices can be controlled. An
alternate user interface provides instant, one-button access to more than
150 audio cuts on a keypad.
Another total system concept is
Master Control from Radio Computing Services (RCS), available in three
basic packages. Model 100 is designed
primarily for the satellite affiliate, while
model 200 includes additional features
for live- assist operations or full local
automation, including LAN capacity.
Model 300 is the top-of-the -line system that can be configured for more
than 9,900 minutes of on-line storage.
Other software modules available in the
package provide music selection,
song information, radio research, news, inventory, traffic and schedule management.
Dalet, a French company, offered a highly
developed, fast and flexible, networked audio
management /automation system in use at
many large facilities around the world. A
modular approach allows the system to be
used in small configurations with simple
migration to larger systems as needs grow.
Manual and automated on-air operation is
supported, including satellite interface and
outboard device control.
McCurdy debuted a PC -based digital audio
storage system called McCart, which allows
networked access of up to 100 control stations to common, redundant storage of more
than 3,000 hours of audio on SCSI -2 drives.
Mixed sampling rates and APT x-100 data
reduction are supported, and AES/EBU digital I/O is available. Control can originate from
a mix of dedicated push- button panels, touchscreen or mouse/trackball devices. An outboard automation package can control the
system, and external device control is also
provided.
An interesting system called MAR was
shown by the Spanish manufacturer AEQ. It
features ISO /MPEG Layer II (MUSICAM) audio coding and comprehensive DTMF remote
control. The system can be networked via
LAN, and its control options include touch screen, mouse/keyboard or dedicated hardware panel. AES/EBU audio I /Os are offered,
along with multiple language capability for
the on-screen displays. The system supports
live and automated operations including telephone hybrid control.
Basys Automation Systems again exhibited
its D -Cart, a powerful multi-user recording,
editing and playback system. For stations
using the Basys Newsroom computer system, the D-Cart interface ties both systems
together on one screen. Editing functions
are precise, non -destructive and intuitive,
and the system's playlist feature allows any
number of items to be assembled in a
sequence for broadcast. Each item can be
triggered automatically by the previous
item, or simply cued for playback in order.
A DTMF interface allows reporters in the
field to file reports unattended with time/
date stamping of each feed.
Auditronics has reconfigured its Destiny
2000 system, now using two standard video
displays instead of a single touchscreen. A
new hard disk system has also been incorporated, while the overall concept of integrating hard disk, CD changer and analog
console into a user -friendly, flexible package for live, live- assist or walkaway has
remained and been refined.
Scott Studios showed its CompuCarts
system, which provides a low-cost, PCbased replacement for cart machines. A
simple, dedicated push-button controller
is used with the system. Audio database
management is included, and traffic software bridging is provided. The new Troll

Wolf Coach's Benchmark van, in-
troduced at NAB '93, is being delivered at the
rate of nearly one per week. Although promoted as built -on assemble basis, this vehicle is
not a stripped down ENG van. This unit can be
custom tailored for 1- person operation, multicamera use or equipped with a single mast RF
repeater capability. Also available from Wolf
Coach is the cable drive mast. Known for its
quick deployment and retraction, the mast
now features power-down retraction. This
overcomes the problems of ice build -up stopping the mast.
Will -Burt, an experienced builder of telescoping masts, demonstrated its new electromechanical telescoping mast. The unique drive
train uses technology similar to the remote

Satellite news vehicles
The newest addition to the Harris Allied fleet
of SNVs is the S-21. Available in two body
lengths of 11 feet or 121/2 feet, the S-21 is
equipped with either a 1.8m or 2.4m antenna
along with four racks for equipment.
At Frontline the trend was toward larger
vehicles. Many affiliate stations are drawn to
the SNV -8000 with six or seven racks, GTE
Skyswitch communications package and video production capability. If the commercial
driver's license (CDL) is a concern, Frontline
offers a 6 -rack SNV built on a Ford F -700. Both
models are available with a dual path waveguide
option, allowing transmission of two different
video signals on same or opposite polarity on
the satellite. For smaller vehicle needs, a 4-rack
version on a Chevrolet P -30 with RSI 240KV0
antenna is also available. Its 11 foot, 4 -inch
height allows it to fit in many garages and
under low bridges.
Wolf Coach unveiled the Power Truck, a design developed from the collective input of
seasoned operators. It is fitted with seven
equipment racks and a half -rack to mount 2way radios, telephones and other gear previously mounted on the walls. It can accommodate 10 seated operators, yet it's smaller and
lighter than traditional SNVs. It offers lots of
exterior storage space but maintains its GVWR
under 26,000 pounds and does not require a
CDL. Wolf Coach also showed off an SNV with
a 3.7m antenna using a proprietary aiming
mechanism.
BAF Communications offers the
largest selection of SNVs from the REPLY CARD
FE-42 built on a Volvo FE chassis
to the SD-22 SNV on a Ford Super

RF transmission for radio
Following a general
trend of NAB '94 toward digital replacement technologies,
Nautel showed its NE50
citers and transmitters. The 377C-1A
and 377D-1 and -2 provide automatic and manual RF switching for AM
and FM transmitter sites. Also
shown were the 802B FM exciter
and 816R-6C 30kW FM transmitter.
Thomcast showed the usual wide
range of radio transmission products. Most interesting among new
radio items was ALLISS, an adaptable, integrated, high -power shortwave transmission system. Comark,
another part of the Thomcast organization, announced that it acquired the RCA Broadcast Transmitter Service Business & Parts
from General Electric.
QEI introduced the Quantum series of solid -state FM transmitters
and the QEI 675B, an advanced technology FM exciter.
Circuit Research Laboratories
(CRL) had its usual fine array of goodies. The CRL SC-100 enables a broad-
caster to enter the potentially lucrative radio broadcast data system
(RBDS) field. It can be programmed
and controlled with an external PC via
RS-232 (directly or via modem), or via
the unit's own front-panel keyboard.

This solid -state device
uses 32 -bit direct digital synthesis (DDS)
technology to generate
a modulated FM carrier of exceptional spectral purity and audio
fidelity. By avoiding the
use of a conventional
VCO, instability and
non -linearity are avoided.
Harris also brought
back its digital FM exciter, DIGIT, this time as a real product
ready for market. Claimed as the
world's first such exciter (it was first
introduced two years ago), this device now makes it possible to have a
completely digital FM operation from
audio input to RF output. Thus, all A/
D and D/A converters and associated
distortion are eliminated, as are intermediate interfaces. Its audio specifications are impressive, and this exciter appears to ratchet FM broadcasting up another notch on the quality
scale.
Continental Electronics recently announced three control panels for ex102

TCX 100 FM exciter with lots of bells
and whistles.
Crown Broadcast showed the FM
200, a 200W solid -state FM transmitter.
Completely self -contained, it meets FC,
DOC and CCIR technical requirements
and makes a perfect emergency or
standby unit for the FM broadcaster
who does not wish to spend thousands of dollars for a standby unit.
Broadcast Electronics offered the
fourth in its series of solid-state FM
transmitters, the FM-3C. It uses the FM100C exciter, and the VSWR foldback
allows operation even under the worst
conditions of VSWR mismatch. Redundancy in the power supplies allows for
operation even if the RF or its power
supply drops out.
Electronics Research Inc. (ERI) was
showing the new "X" series of FM antennas and Lambda antenna mounting
system. The Lambda system custom
tailors the antenna /tower interface to
provide optimum pattern control and
coverage for stations.

Speaking of EBS, the
FCC's interest in this
topic is reflected in
TFT's EIS 911 system.
Since its demonstration earlier, TFT has
modified it and reduced its potential
costs. A fascinating "freebie" was also
found at the TFT booth. Although
priced at $20 on the inside page, the
primer "Digital Aural Studio to Transmitter Links" is actually free from TFT
for the cost of a letter to the company.
Although TFT equipment is referenced
throughout the book, the
theory of digital STL is well
developed and explained.
Microwave systems
QEI has adapted its uncompressed
CAT -Link technology to the RF spec-
trum to come up with Quick-Link. (See
"1994 NAB Pick Hits," p. 24.) It is a digital
transmitter /receiver pair that provides
a stereo pair of 10Hz to 15kHz channels for radio or TV aural remotes. As
a bonus it can also be used as a backup
for a 950MHz aural STL using existing
coaxial cable and dishes. It uses the
902- 928MHz band as a Part 15 device
with direct sequence spread spectrum
transmission. Ten front -panel selectable channels can be accommodated.
Dolby Labs demonstrated a new 4channel version of its DSTL digital
950MHz aural studio -to- transmitter
link. The new DP5503
and DP5504
transmitter and receiver provide four
audio channels and two RS -232 data
channels in an occupied bandwidth of
only 400kHz.
DB Elettronica highlighted a complete line of FM and TV products including the TD/16 and RD /16 digital

Harris also showed a line of solid state UHF transmitters with models
for 5kW, 10kW and 15kW. The transmitters use broadband modules that
are interchangeable for visual and
aural service.
The Acrodyne booth teemed with
innovation as vice president of engineering Dr. Tim Hulick demonstrated
his company's latest wares. Shown

is reversed because this year Comark
obtained the license rights to use the
RCA trademarks for transmitter and
professional broadcast studio equipment, including the use of "Nipper."
Though this doesn't necessarily mean
any big change in the Comark transmitter line, it is important in that parts
and technical assistance for existing
RCA transmitters are now available
through Comark. Also at NAB was
Comark's new UHF TV transmitter,
which uses an IOT final power amplifier and has Class A amplifiers as
drivers to minimize the overall system correction needed.
Another wedding of companies has
resulted in Larcan-TTC with a new
line of UHF transmitters, also with IOT
finals. There was also a joining of
forces between Marconi Communications and Continental Electronics.
The technology will be provided by
Marconi with the equipment actually
being manufactured by Continental.

Transmission line and antennas
Andrew Corporation displayed a new type of
rigid coaxial line called HR Line, which
bolted together inner conductors that eliminate
contact sliding between sections. Thermal expansion is accommodated through a spirally
grooved inner conductor. There is no wear at the
junction between sections, and VSWR numbers
are comparable with rigid line systems. For HDTV,
Andrew was showing the Super -Alp antenna, At
which is essentially a higher-power version of
the Alpine LPTV /translator antenna system.
Dielectric Communications placed emphasis
on its TUP panel antenna, which is designed for
emergency high -power operation, as well as digital HDTV at any future channel. Digital transmission requirements have spread to transmission
line. At first thought, it might seem a little strange
to specify a digital transmission line
after all,
a piece of coax probably doesn't know or care
what it is carrying. However, Dielectric Communications does not agree. Its new digiTLine has
been designed to combine the best features of
rigid copper coax and semi -flexible lines.
Cablewave showed its line of transmission line
products with emphasis on the 6 1/8inch flexwell cable. Shown in the MYAT

Noteworthy new product
In addition to the 10 Video Pick Hits, the judges felt one other product deserved to
be mentioned. The BTS Media Pool was shown in a suite at the convention, and
therefore ineligible for a Pick Hit. Despite this, many of the judges attended the Media
Pool showing and felt it deserved recognition.
Media Pool is an expandable multichannel tapeless video recording system. The
unit's architecture is based on RAID technology, where multiple disk drives are used
to build a large block of memory. The system offers variable data compression, and
allows users to determine how much, if any, compression is used on each clip. All
modules are redundant and hot swappable. At present, software applications allow for
emulation of digital cart machines, VTRs and variable delay capabilities. The unit is

Using fiber for
satellite systems
Using off-site earth terminals no longer involves costly
links and cumbersome operations.
By Philip Hejtmanek
Most
The Bottom Line
Line -of-sight or space limitations have forced many TV
stations (especially those in
downtown areas) to locate their
satellite receive terminals offpremises. This has implied
expensive microwave or telco
links between locations. It also
typically requires extensive
coordination with additional staff
and/or the use of a commercial
teleport. Given the growing use
of satellite feeds, a new, cheaper
and more flexible alternative
should be welcome wherever
remote downlinks are required.
TV
broadcast stations depend
heavily on satellite feeds for network and
syndicated programs, news feeds, commercials and other program material.
The construction of the receive terminal
for these programs is usually a simple
matter of putting up a satellite earth
station in the parking lot or backyard of
the station. It is not always that easy,
however.
Consider an example of a major market
TV station operating from a 3 -story building surrounded by skyscrapers. There is
no useful view of the satellite arc anywhere on the station's property. As a
result, the station acquired the needed
program material from satellite feeds via
local teleports at an extremely high cost.
Even the station's primary network feed
was downlinked tens of miles and three
microwave hops away. As a result, incoming path resources were scarce and needed to be scheduled carefully. Each program feed used up one of the limited
number of lines into the facility.
The station had investigated the possibility of a remote-controlled earth station, but concluded that coordinating the
large number of necessary microwave
circuits would be untenable. Although
fiber -optic paths had recently become
available from common carriers in the
market, the need to lease a single circuit
per program at comparatively high cost
made that option prohibitive as well.
Sending RF via fiber
Eventually, station engineers turned to

technology more commonly used by cable operators. It was well known that
major cable MSOs were replacing the
coaxial cable and amplifiers on their longhaul trunks with fiber. This allowed a
reduction of the number of amplifiers
between the head-end and the subscriber, which translated into less noise and
better reliability.
These fiber-based systems employ highperformance intensity modulators and
wideband, single-mode fiber to transmit
the entire 400MHz or 500MHz bandwidth
of the cable system to high -linearity photodetectors at neighborhood nodes
throughout the service area. RF output
from the photodetector is fed into a standard CATV wideband trunk amplifier and
passed from the nodes to individual subscribers' homes in traditional manner
via coax.
Clearly, the bandwidth of these fiber
systems would be adequate to convey
the entire frequency spectrum of a satellite downlink if the RF was downconverted. An examination of current periodicals relating to the cable and laser industries revealed that there were available products optimized for use in remote satellite downlinks. One such product, from Ortel Corporation, carried
500MHz of bandwidth at the common Lband IF frequency (950MHz to
1,450MHz). It also carried another
500MHz at the C -band RF downlink carrier- frequency spectrum of 3.70GHz to
4.20GHz. In other words, one fiber strand
could carry 1GHz of RF bandwidth across
as much as 35km of single-mode fiber,
with baseband video signal -to-noise per-
formance of better than 60dB.
The advantages of such a system are
substantial. A remote earth station that
conveys the full RF spectrum of the satellite to the station allows multiple simultaneous feeds to be received on stationbased hardware, via a single fiber path
from the downlink.
For the most versatility in a broadcast
operation, a steerable satellite antenna
with a 4 -port C /Ku feed is the best choice.
This provides all four possible RF polarizations that could be encountered (Cband H and V, Ku -band H and V) at the
station. However, it requires two fiber
strands for full-time dedicated access to
all feeds from any given satellite. (See
Figure 1.) Alternatively, the C -band or Kuband outputs from two separate antennas could be applied to the same 2 -fiber
path for simultaneous access to two different satellites.
carrier that the fiber will be used only
for a specific, in -house RF application.
In the example cited earlier, the negotiation of contracts and leases for a 5km
dark fiber path and the earth terminal
site took much longer than the actual
construction of the facility.
Getting fiber into the facility
Fiber-optic lightguide is rapidly replacing coaxial cable as the medium for
video transmission via common carrier.
Future TV station connectivity is certain
to include analog and digital transmission by fiber. If your station is not yet
connected to a fiber vendor, it might be
worth the effort to investigate the availability of fiber resources before the rush
is on to deliver a needed circuit.
Installation may involve digging up the
street, installing manholes, pulling cable and a time -consuming splicing process. Fortunately, the fiber vendors handle most of these details, but the user is
generally subject to an installation cost.
Fiber vendors will want to establish a
point of presence (POP) in a TV station,
similar to the telco demarcation point.
The location of the POP is dependent
upon the requirements of the customer
and the expected uses of the fiber. It
consists of a panel with multiple connectors, one for each strand in the fiber
cable. The vendor will also place any
required terminal equipment and power
supplies at the POP.
For earth station telemetry, status and
other control signals (such as antenna
motion control for steerable dishes), separate telco data lines may be required.
Finding the fiber
some cases, a broadcast operation
can secure utility rights -of-way and lay
its own fiber between the earth station
and the control facility. More commonly,
however, the broadcaster will lease fiber pathways from a common carrier.
For the RF application required by this
type of project, the common carrier
must provide the broadcaster with dark
fiber. Dark fiber is a fiber -optic path without any telco- provided terminal equipment (the equivalent of a dry pair in
telco's copper environment). This may
be harder to obtain than standard fiber
service in some cases, because of the
carrier's fear that the customer will use
the fiber to offer competing service. A
broadcaster may need to affirm to the

vember 1991 -January 1992.)
The small diameter lightguide used in
single -mode fiber allows only light rays
that are directly coupled into the fiber
to propagate. The larger diameter multimode variety allows direct propagation
and other modes of coupling. The latter
are created when light that is not precisely coupled into the fiber reflects off
the cladding and arrives at the far end,
slightly delayed in time relative to the
direct-coupled light. This modal dispersion results in substantially poorer bandwidth per kilometer of fiber. Single -mode
lightguide is about one -tenth of the diameter of a human hair and is spliced or
mated to a connector using a microscope. Of course, the thin glass strand is
surrounded by many layers of strengthening material, so the actual fiber cable
is quite robust.

Some fiber facts
Fiber -optic cable consists of an extremely small glass core, surrounded by a cladding material that has a different index of
refraction from the core. Light from a
laser or LED is coupled into the fiber and
travels down its length to a photodetector at the other end of the path. The fiber
is frequently optimized for the wavelength of the light to be transmitted. Typically, infrared lasers with wavelengths
of 1,310 nanometers or 1,550 nanometers are used as light sources in highperformance systems. (See BE articles,

high -performance digital and RF

Radio Operators
Certification Handbook
The Radio Operators Handbook is the SBE study guide
for the radio operator certification exam, which is part of the
SBE's multilevel certification
program.
The handbook covers topics
from the old Third Class license exam that apply to radio station operators. It also
covers practical skills required
by operators that are beyond
the scope of the FCC rules.
By completing the handbook you
can take an exam for certification
by the SBE. Exams are given twice
a
year by volunteer members of
local SBE chapters. Membership
in the SBE is not required to be
certified. An application of certification testing is included in the
back of the handbook. The cost of
certification testing is included in
the handbook's price.

degradation attributable to the
fiber path. This compares favorably with the seasonal adjustments that previously had been
required at the station to maintain its microwave video circuits
from teleports.
Reliability of the optical transmission path has been 100% to
date. The station quickly began
using the antenna for daily news
feeds and syndicated program
pickups. It has since canceled a
substantial number of longstanding orders with local teleports. The system is projected to
pay for itself in saved teleport
charges within the first year. For
other stations faced with these
similar circumstances, this approach seems worthy of serious
consideration.

FIT 3 -CCD Digital Signal Processing Camcorder
Three high -density 380,000 pixel CCD5 with half -pitch
pixel offset to over 700 lines of horizontal resolution, a S/N
ratio exceeding 60dB and remarkable sensitivity of 18 at
2000 lux result in simply extraordinary image quality.
Additionally the Frame Interline Transfer (FIT) CCDS minimize vertical smear, so you maintain impressive picture
quality even in very bright illumination.
Uses advanced digital signal processing circuitry which
provides four valuable benefits.
1) Consistently reliable up-to-spec performance.
2) Fine adjustment of a wide range of parameters.
3) Memory storage and instant recall of specific settings.
4 More flexible and higher quality image processing,
as well as easier maintenance.
Some of the DSP circuits and their functions:
- CHROMA DETAIL - This function compensates for poor resolution in the high chroma areas of the picture.
- DARK DETAIL - Determines optimum degree of contour enhancement in dark areas to deliver crisp, natural-looking images
- HIGHLIGHT COMPRESSION - Expands the dynamic range of the highlighted areas and prevents halation. The highlight compression circuit allows a wide dynamic range producing detailed images even against bright backlight or daylight.
- FLARE CORRECTION CIRCUIT - Compensates for unsteady black caused by light or by a subject's movements.

The Logic Series DIGITAL batteries are acknowledged to
be the most advanced in the rechargeable battery industry. In addition to the comprehensive sensors integral to
all Logic Series batteries, each DIGITAL battery has a
built -in microprocessor that communicates directly with
Anton /Bauer InterActive chargers, creating significant new
benchmarks for reliability, performance, and life. They
also complete the communications network between battery, charger and camera. With the network in place, DIGITAL batteries deliver the feature most requested by cameramen: a reliable and accurate indication of remaining
battery power.
DIGITAL PRO PACS
The Digital Pro Pac is the ultimate professional video battery and is recommended for all applications. The premium heavy duty Pro Pac cell is designed to deliver long life
and high performance even under high current loads and
adverse conditions. The size and weight of the Pro Pac

or just

chat from early

seven days a week and
because we combine our
sales and service into one
customer support operation, you'll most likely be
speaking to the same person that sold you your
SADiE. And if your system
stops working
(
don't let
anyone tell you "breakdowns never happen!" ) cus-
tomer support will get you
up and running again as
rapidly as possible. As our
support team often work

we know you are the best advertisement for SADiEN so free
software updates are a sound investment for all of us.
Finally, we don't try to make money out of maintaining your
SADiEt - an extended

you less than $1,500 and you don't have to purchase it until the end
