The Digital Processing Systems DPS-470 Digital Component AV

Synchronizer is a 10-bit video synchronizer, or audio/video synchronizer, featuring serial digital and analog component, composite and Y/C input and outputs. It is available in both video-only and audio/video configurations. In either configuration, the DPS-470 provides an ideal bridge between analog video signals, such as satellite and microwave feeds, and a digital production facility.

Four different input and output formats are provided: u

Serial Component Digital Video (SDI) u

Component Analog Video (Betacam / MII) u

S-Video (S-VHS / Hi8) u

Composite Video

An adaptive comb filter decoder and 10-bit ITU-R-BT.601 component processing provide maximum signal transparency. A built-in auto-sense TBC circuit provides seamless mode switching between direct color and heterodyne sources such as camcorders and VCRs.

The DPS-470 is also a transcoder and a digital test signal generator. In Test

Signal Generator (TSG) mode, any one of 33 different NTSC (29 PAL) 10bit test patterns can be selected to appear at all four outputs. The operator can specify which test signals are used by the built-in Vertical Interval Test

Signal (VITS) inserter.

With the addition of a DPS AS-470 four-channel audio synchronizer module, the DPS-470 can provide dual stereo audio and video synchronization in a single rack unit high package. The internal audio synchronizer option supports balanced analog, AES/EBU digital and embedded SDI audio I/O.

All outputs are simultaneously active, which enables both analog and digital audio devices to be connected at the same time. Incoming stereo audio pairs can be selected from the analog, digital or embedded SDI inputs. All four audio channels dynamically track the internal delay of the video

DPS-470 Operator’s Manual

synchronizer whenever auto-track mode is enabled. Up to 20 NTSC (12

PAL) fields of fixed delay can also be specified, ensuring proper lip sync regardless of the program source. All audio parameters are controlled from an easy-to-use front panel menu. A variety of DPS multi-channel remote controls are also available.

The DPS-470 serial digital component synchronizer represents the ideal choice for broadcasters beginning their transition to DTV. When interfacing analog audio and video sources to serial digital equipment, nothing offers flexibility, performance, reliability or economy of the DPS-470.

This manual represents operating instructions for both the NTSC and PAL versions of the DPS-470. Please pay special attention to the differences in these two standards which are noted in parenthesis.

Mounting

The size of the DPS-470 allows it to fit into most standard consoles or

19-inch racks. If the unit is to be mounted in a rack, then rack slides or trays must be used for support. Care must be taken to select a dry, well-ventilated location with a minimum of dust and vibration. Also, leave sufficient clearance from the unit’s rear panel to allow for proper air circulation.

After unpacking the unit and before installing it in a console or rack, allow at least 30 minutes for temperatures to equalize and to eliminate any condensation that may have developed.

Installation and Configuration

Jumper Settings

AES/EBU is comprised of 2 channels each transmitting (output) and receiving (input) audio. The channels are independent and can be set to transmit XLR balanced (110 ohms) audio or BNC unbalanced (75 ohms) audio. You could also configure the input as XLR and the output as BNC, or vice-versa. Do not use the XLR and BNC connections for the same input or output channel at the same time. In order to select the right impedance on each channel, you must configure the jumper settings on the audio board’s

PCB. The headers are labeled DJP1, DJP2, DJP3 and DJP4. An arrow points to pin 1 on each header. Use the following diagrams to configure the jumpers to the desired settings. Please note that the BNC unbalanced

(75 ohms) audio is the factory default. Also, depending on how the jumpers are set on the board determines which of the cables are active on the breakout cable.

Video Inputs

S-Video Input

Component Analog Video Input

These BNC connectors, labeled Y-IN, R-Y IN, and B-Y IN, are used to input the signals from analog component devices, such as Betacam cameras or

VTRs.

Serial Digital D1 Input

This 4-pin connector, labeled S-VIDEO IN, is used for S-Video signals, like

S-VHS or Hi8. It is normally connected to the S-Video output of a playback

VCR using a standard 4-pin to 4-pin S-Video cable. Some JVC ‘industrial’ type S-VHS players use a 7-pin connector for their S-Video output. To interface with such machines, a 7-pin to 4-pin adapter cable is required from the manufacturer of the VCR.

This BNC connector, labeled SDI IN, accepts serial digital ITU-R BT.601

video and embedded audio data at a rate of 270 megabits per second.

Composite Video Input

This BNC connector, labeled COMPOSITE IN, is used to feed composite

1 Vp-p video to the DPS-470. In Synchronizer Mode, the input video signal can be direct color or monochrome; in Timebase Corrector Mode, the input signal can be connected to the video output of a VCR.

Video Outputs

Serial Digital D1 Outputs

These BNC connectors, labeled SDI OUT, provide the synchronized/timebase-corrected serial digital ITU-r-BT.601, 270 megabitsper-second output.

Composite Video Output

These BNC connectors, labeled COMP-1 OUT and COMP-2 OUT, provide synchronized/timebase-corrected versions of any of the input signals, except when the DPS-470 is in either Bypass or TSG mode (for a discussion of the output in these modes, see the “Synchronizer Mode” section in Chapter 3).

The COMP-1 output can be bypassed from the front panel or will automatically do so when the DPS-470 is turned off.

S-Video Output

The synchronized /timebase-corrected S-Video version of the video input signal is part of the Multi I/O connector (see below).

Component Analog Video Output

The synchronized /timebase-corrected analog component video output is part of the Multi I/O connector (see below).

Multi I/O Breakout Cable (Component, S-Video, GPI)

A DB-15F high-density connector, labeled MULTI I/O is located on the right-hand side of the rear of the DPS-470. This connection and breakout cable contains the connections for Component Out, S-Video Out and GPI.

ntsc-pal-141.qxd 4/4/00 2:25 PM Page 9

Chapter 2:

Connections

Genlock Reference

These BNC connectors, labeled REF LOOP, are used to loop a genlock signal through the DPS-470 to establish the timing for its video output signal. The signal for this input must always be stable, such as the output from a black-burst or color-bar generator. Do not attempt to use a signal that has not been timebase-corrected. When a valid signal is connected to the

REF LOOP input, the video output of the DPS-470 will be genlocked to this signal. When no external reference is supplied to the genlock input, the

DPS-470 will operate using its own internal sync generator. If the second

REF LOOP is unused, terminate it with a 75-ohm terminator.

Audio Inputs

Analog Audio Inputs (Terminal Strip)

The analog audio input accepts 2 stereo pairs. The first pair is considered channel 1 and the second channel 2. Channel 1 and 2 are comprised of two components each, left and right. Please see the diagram of the Back Panel.

The analog audio inputs can be configured to 600

Ω balanced/unbalanced or high impedance balanced/unbalanced audio.

AES/EBU Audio (Breakout Cable)

The following is a description of the breakout cable accompanied with the

DPS-470.

Audio Inputs

The DPS-470 can process 2 stereo pairs of analog audio, 2 stereo pairs of

AES/EBU audio, or Serial Digital (SDI) audio. You can select which

2 stereo channels to be processed. The audio inputs can be selected from the front panel. Since all of the outputs are active simultaneously, inputs can be mixed from any of the analog audio SDI audio or AES/EBU audio.

BNC CH-2

The BNC CH-2 is used for unbalanced AES/EBU audio output on channel 2.

Serial Digital Embedded Audio Output (SDI)

Any of the selected audio inputs can be embedded into the output of the SDI stream.

Remote Control Ports

In addition to remote triggering of the Freeze function via the GPI interface, all functions of the DPS-470 can be remotely controlled by devices capable of either RS-232 or RS-422. The DPS-470 is the first DPS studio product to also feature a DPS Coaxial Network (DCN) port. The type of control is selected in the Configuration Menu, under the Remote Control sub-menu

(see Chapter 3, “Operation”).

RS-232 and RS-422

This DB-9F connector is used to remote control the DPS-470 via either

RS-232 or RS-422. When this port is in use, a Unit Address must be set to an appropriate value in the range of 1-127. This allows the DPS-470 to be used in a multi-drop configuration where only the unit addressed will respond to remote commands.

DCN Port

This BNC connector is used to provide a DCN (DPS Coaxial Network) interface for remote control and status monitoring. DCN is a simple proprietary network in which 75-ohm coax is used as a multi-drop, bidirectional network. Using a BNC T connector on the DPS-470, loop coax between each DPS-470 and RC-4000. At each end of the chain, install a

75-ohm terminator. Every DPS-470 is assigned a unique DCN address at the factory, so there is no software configuration required. Maximum cable length (total) in a DCN configuration should be limited to 2000 feet.

Remember to enable DCN at the DPS-470 front panel when using the

RC-4000.

11

ntsc-pal-141.qxd 4/4/00 2:25 PM Page 12

DPS-470 Operator’s Manual

Use with RC-4000

To control the DPS-470 from a RC-4000 remote control panel, any of the above ports may be used. However, for new installations, the DCN port is recommended. If using the DCN port, then you may use the “Search for devices” menu option on the RC-4000. The RC-4000 will find all DPS-470s attached to it’s DCN port and configure itself to control them. This may be done for any number of units at one time. DCN also allows multiple

RC-4000s to control a single DPS-470.

To use RS-232 or RS-422 for control, the normal installation procedures should be followed on the RC-4000. The DPS-470 uses MIDI for its control protocol and must, therefore, be connected to a port configured for MIDI devices. Similarly, the baud rate and line type (RS-232 or RS-422) must match between the RC-4000 and the DPS-470. The cables required are straight connections (e.g., pin 1 to pin 1), but custom cables will be required to operate in multi-drop mode where multiple DPS-470s reside on a single

RC-4000 serial port (see the RC-4000 manual for examples).

It is possible to remotely disable and enable the front panel of the DPS-470 from the RC-4000 using the “KeyLock” option. If neither this option nor the rear-panel KEYLOCK switch is activated, then it is possible for a local user to modify the remote-user’s settings from the front panel. However, the

RC-4000 will periodically poll the device and show the new parameters if the local user changes them. If remote control is the usual case, then it is probably best to disable front-panel access once the device has been installed.

Switches

Keylock

Term

There are two toggle switches on the back panel, labeled KEYLOCK and

TERM.

When this switch is down, or in lock position, none of the front panel keys will function.

This switch terminates the RS-422 receive signal. Engage it when more than one unit is connected to the DPS-470 via RS-422.

If you purchased the Audio Option board separately from the DPS-470, you will need to install it. Please use the following instructions on installing your audio card safely and correctly.

Precautions

WARNING: Static Electricity!

Static electricity from your body can damage your Audio Card or the

DPS-470. Even though you may not notice it, static electricity is being generated every time you move. Usually, it is too small to cause a spark, but it can still cause damage to sensitive electronic components.

• To prevent this damage, you should handle the Audio board carefully.

• Do not take it out of its conductive bag until you are ready to install it.

• Do not carry the board around the room unless it is in its conductive bag.

• Avoid wearing wool or polyester clothing while installing the Audio board. These fabrics generate more static electricity than cotton garments.

• Before touching the Audio board, you should discharge any static electricity from your body by first touching the ground metal chassis of the DPS-470.

Installing the Audio Board

1.

Confirm that the DPS-470 is shut off and that the power cord is disconnected from the rear panel.

39

ntsc-pal-141.qxd 4/4/00 2:25 PM Page 40

DPS-470 Operator’s Manual

2.

Remove the top cover from the DPS-470. Use a Phillips screwdriver to remove the fifteen retaining screws and lift off the top cover. Please retain the screws, as they will be used to secure the top cover. Please note that the five front panel screws are different that the other ten screws.

3.

There are six screws that must be removed from the main board of the

DPS-470 and replaced with the supplied six standoffs. Use the following diagram to determine which screws are to be removed.

40

4.

Once the screws are removed, replace them with the supplied standoffs.

5.

Three ribbon cables and a power cable are supplied with the Audio board. These cables are attached from the main board to the Audio board. There are two 34-pin cables and one 20-pin cable. To attach these cables to the main board, make sure that the red line on the ribbon cable is aligned with the arrow on the silkscreen next to the header pins on the board. The power cable is connected from the main board labeled CN20 to the Audio board. (See the above diagram)

6.

Remove the Audio board and the metal shield from their conductive bag.

7.

Using a hex driver, remove the two hex nuts on the DB25 on the back of the board.

ntsc-pal-141.qxd 4/4/00 2:25 PM Page 41

Appendix C

8.

Affix the metal shield and the Audio board over the standoffs.

9.

Use the supplied screws to secure the Audio board and the metal board to the Main board.

10. Connect the ribbon cables and the power cable to the Audio board.

11. Replace the hex nuts on the DB25 to secure the connector to the chassis of the DPS-470.

12. Replace the top cover and the fifteen screws to secure the top cover. Be sure to replace the five different screws to the front panel.

13. Plug the power cord back in.

This appendix describes the serial data interface to the DPS-470. This information is intended for users and programmers who want to develop their own custom control (driver) software.

Electrical Interface

The electrical interface for the DPS-470 is RS-232, RS-422 and DCN. The bit rate is set to 9600 bps, with 8 data bits, 1 stop bit and no parity. For DCN the bit rate is always 38,400 bps.

Protocol

The software protocol is a MIDI compatible format, using the system exclusive feature of the MIDI interface. Communication with the DPS-470 is initiated when the system exclusive command byte (F0 hex) is received, followed by the ID code (67 hex).

The next byte sent is the address byte, which determines which unit is being addressed by the command. This is followed by a unit function select byte and one or more data bytes. The communication is completed when the

MIDI end system exclusive byte is sent (F7 hex).

The following table summarizes the protocol:

Host:

System Exclusive Byte (= F0 hex)

Unit ID Byte (= 67 hex)

Unit Address Byte (= 00-7F hex)

Function Select Byte (= 00-7F hex)

Data Byte 1

Data Byte 2

....................

Data Byte N

End System Exclusive (= F7 hex)

43

ntsc-pal-141.qxd 4/4/00 2:25 PM Page 44

DPS-470 Operator’s Manual

System Exclusive Byte

This byte is used in the MIDI protocol to allow manufacturers of MIDI equipment to define messages specific to their own equipment. The system exclusive mode remains in effect until the end system exclusive command is sent.

Unit ID Byte

Unit Response:

ACK Byte (= 06h) or NACK Byte (= 15h)

This byte is the unique code that identifies the exclusive data for the particular unit.

Unit Address Byte

This byte determines to which DPS-470 the following command is directed.

The address of each unit can be set using the front panel menu commands.

Unit addresses correspond to hex codes as specified in the following table:

DPS-470 Unit Address

Unit 1

Unit 2

Unit 3

Unit 4

Unit 5

........

Unit 126

Unit 127

Corresponding HEX Value

01h

02h

04h

05h

........

7Fh

Unit Function Select Byte/Data Byte(s)

The Function byte determines which function on the addressed card will be affected by the command. Most commands follow this byte with two characters that represent the new hex value for the selected function. The following table lists each function with the associated data bytes.

NOTE: Parameters for functions are sent in ASCII, i.e.,‘00’ => 30h + 30h, ‘01’ => 30h + 31h, etc. ...

DPS-470 responds with the following status byte (followed by the normal

ACK byte).

Bit 7

Bit 6

Always 0

(Genlock Status)

Bit 5 (Input Video Pres)

1 = Genlocked

0 = Free-running

1 = Input present

0 = No Input present

Bit 4 (Freeze/Live Mode) 1 = Freeze mode

0 = Live mode

Full DPS-470 Status

Command 0Eh requests a complete status dump from the addressed

DPS-470. Please contact DPS for more information.

Programming Example

Some confusion has resulted from the fact that actual data bytes sent to the

DPS-470 must be in ASCII. The following is an example of the actual data that would be sent to the DPS-470 to force it into monochrome mode. Please note that the data bytes are always transmitted in ASCII.

DPS

We were originally founded in 1975 as Digital Video Systems. We were pioneers in the development of time base correctors (TBCs) and synchronizers. Digital Video Systems was acquired by Scientific Atlanta in

1982 and the focus of the division shifted to satellite encryption technologies. In 1988, the studio video product line was spun off into a new employee-owned company called Digital Processing Systems (DPS). In

1996 DPS went public, with a very successful initial public offering (IPO) of over three million shares.

Today, while DPS continues to innovate on and expand its line of traditional broadcast products, the company experiences significant growth in the computer video marketplace. Digital Processing Systems entered the computer video field in 1991 with the introduction of the DPS Personal

TBC, the first infinite window TBC on a PC card. The DPS Personal TBC’s combination of features, performance and price was unique, and competed with units selling for three times its cost. After the success of this TBC card,

DPS followed with the Personal TBC II, III and IV, each of which provided increased features and performance. Another innovation was the DPS

Personal VScope, the world’s first combination waveform monitor/vectorscope on a PC card.

The DPS Personal Animation Recorder (PAR), a plug-in card which functions as a single-frame recording deck, was introduced soon after the first Personal TBC and quickly became one of our most popular products.

Still selling in both PC and Amiga versions - a testament to how far ahead of the rest of the industry it was - the PAR provides component analog video

(Betacam, MII), composite and S-Video (Hi8/SVHS) outputs.

The DPS Perception Video Recorder (PVR) is a significant advancement beyond the PAR. First shipped in 1995, the multiple-award-winning PVR is a PCI-bus digital video disk recorder which features 10-bit video encoding with 2X oversampling, ITU-R BT.601 4:2:2 processing and an integrated

SCSI-2 hard drive controller. The PVR is also designed to integrate with third-party non-linear editing software.

Fulfilling the promise of the PVR to be “the heart of an advanced digital video workstation,” DPS has built a family of products that work with the

PVR to create a complete video-audio editing solution. These products include: the AD-2500/3500 Component Video Capture daughtercard; the

SD-2500/3500 Serial Digital Video I/O card; the Perception F/X transition effects accelerator card; and the Perception Audio for Video (A4V) board.

Digital Processing Systems 1997 desktop video offerings also became award winners. The DPS Hollywood, an uncompressed digital (D1) video disk recorder, won the “Pick Hit” award at its release during the National

Association of Broadcasters (NAB) convention in 1997. The superb resolution-independent compositing and special effects software program,

Digital Fusion, brought to market in a strategic partnership between DPS and the creators, eyeon Software, Inc., won the same award at NAB ’97.

At NAB ’98 we introduced a major new product: the DPS Perception RT, a dual-stream real-time disk recording and editing system. It won an “NAB

Prime Time Product” award, and three of our other products also won awards.

In addition to an expanding line of video products that “push the envelope” of price and performance, DPS continues to extend its capabilities in other ways. In the summer of 1997 we purchased the award-winning software company Star Media, creators of the Video Action line of video editing software. They are now “DPS Software.” The integration of our traditional hardware strengths with some of the industry’s best software should help us maintain our position as a leader in desktop video solutions.

A key contributor to the quality and remarkable capabilities of DPS’s computer video products has been our lengthy experience in the broadcast studio field, and our traditional broadcast product line is still going strong.

In 1998 we introduced an innovative product, the DPS Whiplash. This is a powerful disk-based slow motion and instant replay system, which uses a proprietary software algorithm to dynamically optimize field and frame data to provide ultra-smooth slow motion playback. Also new for 1998 was the

DPS-470 Serial Digital Component Audio-Video Synchronizer, equally suited for work in analog, digital or hybrid broadcast studios (and it won a

“Pick Hit” award at NAB ’98).

In 1998 DPS combined its proven digital-disk recording technology with sophisticated software tools and networking capability to create Digital

Detective, a digital video recorder which marks the company’s entry into the security market.
