Sony PCS-G50 – The Business Tool for Visual
Communication
To stay ahead of the pack in today’s tough market, businesses require powerful visual
communication tools like the PCS-G50. Sony has combined advanced audio and video
technologies with useful features to provide a visual communication tool for all businesses.
With the PCS-G50, long distance meetings can be held as if all parties were in the same
room, saving the time and trouble of traveling to distant locations for a simple meeting.
Providing you with a new and powerful means of communication, the PCS-G50 will be a
mainstay for your business.
The PCS-G50 boasts a maximum video transfer rate of 4 Mb/s over an IP network, and it
provides extremely high resolution video. By adopting the H.263 video codec/4CIF format,
the PCS-G50 produces image resolution comparable to that of standard TV broadcasts. It can
also switch to the H.264 video codec for higher throughput or revert to previous versions of
the ITU-T videoconferencing codecs to maintain compatibility with legacy systems.
As with other PCS Series models, the PCS-G50, with its internal MCU (Multi-Control Unit)
capability, supports simultaneous multi-point videoconferences with six (6) endpoints, and a
maximum of 10 endpoints when two PCS-G50 units are cascaded. The PCS-G50 bridges
mixed calls between an ISDN network and an IP network, and speed matches (by connecting
at the endpoint respective speeds) without lowering the performance of the entire system.
Other key features of the PCS-G50 include a site-name display function and the capability to
record audio and video to Memory Stick™ media. The PCS-G50 also incorporates features
such as data sharing, QoS support functions, an encryption function, a streaming function,
and digital whiteboard support, which are all useful features for quality of videoconferencing.
Effective visual communication is vital to move ahead in today’s business. With the featurerich PCS-G50, not only will your visual communication be effective, it will be affordable.

FEATURES
PCS-TL50
High-Quality Video/High-Speed Network
Connection
The PCS-G50 provides excellent picture quality over
both ISDN (H.320) and IP (H.323) networks and fully
supports the latest non-proprietary ITU-T H.264 video
codec standard for maximum customer confidence
and flexibility. When video encoding is in accordance
with the H.263 protocol, the PCS-G50 supports the
4CIF format at a maximum frame rate of 30 fps, and
when in H.264 protocol, it supports the interlaced SIF
format at 60 fields per second. In addition, the
PCS-G50 can achieve a maximum bandwidth of 4
Mb/s with an IP connection, and up to 2 Mb/s with
an ISDN connection using an optional PCSA-PRI ISDN
unit. This combination of high-quality codec and
high-speed network support provides video quality
comparable to standard TV broadcasts.

Multi-Point Videoconferencing at up to
10 Sites Fig 1
Using optional MCU software, the PCS-G50 can be
configured to communicate with up to 5 remote
videoconferencing sites (6 sites total) simultaneously
using either an IP (H.323 protocol) or ISDN (H.320
protocol) connection. It can also support
videoconferences in which the connections are a
combination of IP and ISDN using a bridging
function. And because the PCS-G50 has a
“speedmatching” function, it maximizes performance
by not reducing the higher speed connection to
match the lower speed connection, as is done with
some videoconferencing systems. Moreover, two
PCS-G50 units - each installed with the optional
MCU (H.323) software - can be cascaded with an IP
connection to support a maximum of 10
simultaneous sites. What is unique about the
PCS-G50 is that it provides high quality, H.264 CIF
video and clear MPEG-4 AAC audio, even in a multipoint videoconference. And of course, the PCS-G50
allows users to expand from a peer-to-peer
videoconference to a multi-point videoconference by
simply dialing up new connections.*1
*1
When adding a new endpoint on the same network (IP or
ISDN), the system will default to the lowest resolution
video standard of all endpoints.

During multi-point videoconferences, it can be difficult
to keep track of all of the participants; however, with
the PCS-G50 site-name display function, this is no
longer the case. The PCS-G50 can display anything
from company or branch names to geographical
locations on a monitor, allowing videoconference
participants to keep track of all parties.

Flexible Display Patterns at all Sites
In addition to conventional patterns of display – such
as showing the far-end site on a full screen or
displaying near-end and far-end sites in picture-inpicture mode – a variety of other display patterns are
available with the PCS-G50. Supporting both
4-screen and 6-screen continuous-presence modes,
the PCS-G50 can display the most appropriate
pattern to match the number of sites that are
connected. In both full-screen and continuouspresence modes, the following two display options
are available:
Voice Switching Fig 3
The PCS-G50 defaults to voice switching, which
displays the far-end site that is actively talking on the
monitor when the unit is in full-screen mode. In
continuous-presence mode, the site that is actively
speaking is displayed on the largest of the six sub
screens, and the near-end site is displayed on the sub
screen where the original far-end site was.

Data-Sharing Capabilities/Digital
Whiteboard Support
Data originated on your PC can be shared with your
videoconferencing counterparts, making communication
even more effective. Any image that can be displayed
on a PC can be sent or received*3 in native XGA
resolution, allowing all parties to share data during a
videoconference. In addition, information drawn up
on a digital whiteboard*4 can also be viewed in real
time by all parties participating in a videoconference
or captured and stored for later reference.
Sending data requires the optional PCSA-DSB1S Data
Solution Box (DSB); however, the DSB is not required for
receiving data
*4 Please contact your local Sony sales office for information
on compatible digital whiteboards.
*3
Built-in Streaming Function
To broadcast*5 your videoconferences to a large
audience, for example, with educational lectures or
live corporate speeches, the PCS-G50 features a
built-in streaming function that allows remote users
to log on from any PC using an Internet browser.*6
Simply enter the URL provided by the PCS-G50
administrator into your Internet browser, and you can
have instant access to the active audio and video
from the PCS-G50. With this useful feature,
hundreds of people with access privileges can view
and listen to your videoconference session from
almost any location that has access to a network.
*5
Fixed Site
As its name suggests, the selected far-end site is
continuously displayed on the monitor when the unit is
in full-screen mode. In continuous-presence mode the
selected far-end site is displayed in the largest of the six
sub screens, and the other sites are fixed as well.

Audiovisual (A/V) Recording to
Memory Stick™ Media
Capturing audio and video during a videoconference
is important to keep a record of what was conveyed
during a conference. With the PCS-G50, audio and
video displayed on the main monitor can be
recorded*2 directly to Memory Stick™ media in
MPEG-4 format and can be played back on any PC
using QuickTime® media player.

Superb Sound
Fig 5
The PCS-G50 reproduces clear and natural-sounding
audio using MPEG-4 AAC (Advanced Audio Coding)
at 14 kHz. And a built-in echo cancellation system
minimizes unwanted echoes during a videoconference.
The PCS-G50 is also compatible with a number of
Sony external microphones and speakers, including
unidirectional and omnidirectional models.
Professional A/V integrators will particularly
appreciate the power and flexibility of this system to
be customized for best application match.
For exceptional sound quality in rooms with
conference tables in a U-shape or in a classroom
layout, the optional unidirectional PCSA-A7
microphone is ideal. Up to 80 units can be daisy
chained to ensure that all participants sitting near a
microphone can be heard.
Easy-to-Use Remote Commander®
Unit/Intuitive GUI Fig 6
The PCS-G50 has a number of features that make it
easy to operate. The cursor keys on the Remote
Commander unit can be used to select and call any
one of three contacts, which are pre-programmed
and displayed in the Launcher Menu. Up to 500
contacts can be stored in the PCS-G50 common
phone book for quick and easy dialing. In addition,
the unit supports a call history log, which stores
the last 32 incoming and outgoing calls so that the
user can readily select and dial a recent contact.

With its elegant design and optional stands for both
the camera unit and the codec unit, the PCS-G50
can fit into even the classiest of conference rooms.
In addition, if you wish to place the camera above a
30” to 50” PDP/LCD TV or monitor, a convenient
optional camera/codec stand, the PCSA-STG50, is
available. This stand neatly houses the codec so that
it is behind the TV or monitor and allows the camera
to be placed above for more natural eye contact
during videoconferences.

Memory Stick® Media Support*7
QoS (Quality of Service)
Enhancement Functions
Private phone books can be created and stored on
Memory Stick media. By simply inserting the
Memory Stick media into the PCS-G50, the unit
automatically recognizes and activates the private
phone book, thereby eliminating the need to re-enter
contact information to place a call. Memory Stick
media has a number of other uses, such as storing
captured images, PC-generated data, and digital
whiteboard drawings. The media can also be used
for installing and updating software.
*7
When holding a videoconference over a network, a
common concern is how to maintain video and audio
quality when the performance of the network is
changing. The PCS-G50 provides three advanced
functions*8 to enhance QoS over a network:
Adaptive Rate Control (ARC)
The adaptive rate control function automatically
varies the video data transfer rate to meet changing
network conditions. It also selects the most
appropriate frame rates, which helps prevent video
breakup.
In addition to Memory Stick, Memory Stick PROTM and
Memory Stick DUOTM with an adaptor can be used.
Secure Videoconferencing –
Advanced Encryption Standard (AES)
Real-time Auto Repeat Request (ARQ)
Secure videoconferencing over a network is possible
because the PCS-G50 supports AES 128-bit encryption.
The PCS-G50 offers two encryption modes with an IP
connection, one that complies with the ITU-T H.235
standard, which allows encrypted communication
with other H.235 compliant systems, and another
that is Sony proprietary, which is ideal when
connecting to other PCS Series systems and offers
higher security. When either of these encryption
modes is active, video, audio, and graphics are
encrypted for the duration of the videoconference.
Forward Error Correction (FEC)
The real-time ARQ function recovers lost IP packets.
This is achieved by buffering the packets at the
encoder and resending any that are lost. This feature
helps maintain audio and video quality, and helps
prevent picture collapse even under high network
traffic conditions.
The PCS-G50 employs an FEC function that corrects
errors in transmission at the receiving end. If a
transmission error occurs, the PCS-G50 can repair the
data and accurately reproduce the original video signal.
*8 When hybrid mode is selected, the best balance between these
QoS functions is automatically set to match network conditions.
