Video Communication System
Sony PCS-G50*1 – 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, and digital whiteboard
support, which are all available in other PCS Series models.
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.
*1 Unless otherwise noted, "PCS-G50" in the following text refers to both the PCS-G50 and PCS-G50P.
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.*2 In addition, the
PCS-G50 can achieve a maximum bandwidth of 4
Mb/s with an IP connection, and up to 768 Kb/s with
an ISDN connection using an optional PCSA-B768S
ISDN unit. This combination of high-quality codec
and high-speed network support provides video
quality comparable to standard TV broadcasts.
The PCS-G50P supports a maximum of 50 fields per
second in interlaced SIF format.
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 unique 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.*3
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.
Site-Name Display
Fig 1 Multi-point Videoconferencing at up to 10 Sites
Fig 2 Site-Name Display
Fig 2
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:
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*5 in
native XGA resolution, allowing all parties to share
data during a videoconference. In addition,
information drawn up on a digital whiteboard*6 can
also be viewed in real time by all parties participating
in a videoconference or captured and stored for later
Sending data requires the optional PCSA-DSB1S Data
Solution Box (DSB); however, the DSB is not required for
receiving data
*6 Please contact your local Sony sales office for information
on compatible digital whiteboards.
Voice Switching
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.
Fixed Site
Fig 3
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*4 directly to Memory Stick™ media in
MPEG-4 format and can be played back on any PC
using QuickTime® media player.
AV recording is not supported when AES is active. Also,
graphical data cannot be recorded.
Superb Sound
Fig 4
The PCS-G50 reproduces clear and natural-sounding
audio using MPEG-4 AAC (Advanced Audio Coding)
at 14 KHz. A built-in echo cancellation system
minimizes unwanted echoes during a
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 40 units can be daisy
chained to ensure that all participants sitting near a
microphone can be heard.
To ensure clear sound quality in meeting rooms with
as many as 20 participants at a round or oval-shaped
table, the optional CTE-600 Communication
Transducer is ideal. The CTE-600 is comprised of six
radially arranged unidirectional microphones and one
omnidirectional speaker. The system is designed to
pick up the active speaker's voice while minimizing
background noise, and to project clear sound quality
in all directions. Up to 4 CTE-600 Communication
Transducers can be cascaded using the optional
CTE-A10 Expansion Adaptor.
Stylish Design
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.

Easy-to-Use Remote Commander
Unit/Intuitive GUI
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 preprogrammed and displayed in the
Launcher Menu. Up to 500
contacts can be stored in the
PCS-G50 common address 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

Phone Book
Memory Stick™ Support*7
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.
In addition to Memory Stick, Memory Stick PROTM and
Memory Stick DUOTM with an adaptor can be used.
Secure Videoconferencing – Advanced
Encryption Standard (AES)
Secure videoconferencing over a network is possible
because the PCS-G50 supports AES Encryption, a NIST
(National Institute of Standards and Technology)
standard for encrypting electronic data used in
commercial applications including
telecommunications. When a videoconference is
initiated with the AES feature active, video, audio,
and graphics are encrypted for the duration of the
videoconference. Because of this feature, companies
can hold sensitive meetings, negotiations, and other
similar interactions with confidence that they will not
be compromised.
QoS (Quality of Service)
Enhancement Functions
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 to enhance QoS over a network:
Forward Error Correction (FEC)
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 audio and
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 audio
and video breakup.
Real-time Auto Repeat Request (ARQ)
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.
