The Flagship Sony PCS-G70 - Quality Video Conferencing with
the Utmost in Flexibility
Video conferencing systems continue to evolve as we enter a new era of visual
communication. Sony is leading this evolution by staying ahead of the latest technological
trends in video conferencing and developing systems that meet our customers' demands.
The flagship Sony PCS-G70 video communication system is the latest solution to meet the needs
of our high-end customers.
The Sony PCS-G70 boasts a maximum video transfer rate of 4 Mb/s over an IP network, and it
provides the highest resolution video of all models in the PCS Series. By adopting the H.263
video codec/4CIF format, the PCS-G70 produces image resolution comparable to that of
standard TV broadcasts. The Sony PCS-G70 can also be used with the H.264 video codec for higher
throughput and with previous versions of the ITU-T videoconferencing codecs to maintain
compatibility with legacy systems.
As with other PCS Series models, the Sony PCS-G70, with its internal MCU (Multi-Control Unit)
capability, supports simultaneous multi-point video conferences with six (6) endpoints, and a
maximum of 10 endpoints when two PCS-G70 units are cascaded. The PCS-G70 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 Sony PCS-G70 include a site-name display function, support for up to
five monitors that display far-end sites in addition to the main monitor, and a dual-camera
input, which can be used to provide more video coverage. The PCS-G70 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.
As we enter a new era of visual communication, the feature-rich Sony PCS-G70 will meet user
needs for high-end and large-venue videoconferencing applications.
Sony PCS-G70 Features
- High-Quality Video/High-Speed Network Connection
The Sony PCS-G70 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-G70 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 Sony PCS-G70 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.
Moreover, in addition to the supplied PCSA-CG70
camera unit, the PCS-G70 supports a range of Sony
camera options, including the BRC-300, which is a
16:9/4:3 switchable 3CCD camera providing
exceptional quality video.
- Sony PCS-G70: Superb Sound
The Sony PCS-G70 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 Sony PCS-G70 is also compatible with a number of
SONY external microphones and speakers, including
directional and omnidirectional models. Professional
A/V integrators will particularly appreciate the power
and flexibility of this system to be customized for
best application match.
To ensure clear sound quality in meeting rooms with
as many as 20 participants, 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.
- Multi-Point Video Conferencing at up to 10 Sites
Using optional MCU software, the Sony PCS-G70 can be
configured to communicate with up to 5 remote
video conferencing sites (6 sites total) simultaneously
using either an IP (H.323 protocol) or ISDN (H.320
protocol) connection. It can also support
video conferences in which the connections are a
combination of IP and ISDN using a unique bridging
function. And because the Sony PCS-G70 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-G70
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-G70 is that it provides highquality,
H.264 CIF video and clear MPEG-4 AAC
audio, even in a multi-point videoconference. And of
course, the PCS-G70 allows users to expand from a
peer-to-peer video conference to a multi-point
video conference by simply dialing up new
Sony PCS-G70: Multiple Display Output
In addition to the main monitor output, the Sony PCS-G70
can support up to five additional monitors that can
be used to display the five other far-end sites in a
6-way video conference.
- Site-Name Display
During multi-point video conferences, it can be
difficult to keep track of all of the participants;
however, with the PCS-G70 site-name display
function, this is no longer the case. The PCS-G70
can display anything from company or branch names
to geographical locations on a monitor, allowing
video conference participants to keep track of all
parties. This function is available both on a single
monitor in continuous-presence mode and on
- 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-G70. Supporting both
4-screen and 6-screen continuous-presence modes,
the PCS-G70 can display the most appropriate pattern
to match the number of sites that are connected.
In both full-screen and continuous-presence modes,
the following two display options are available:
The Sony PCS-G70 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: 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.
- Dual Camera and Split Picture Support (H.239 Dual Stream)
The Sony PCS-G70 can be configured with two cameras,
which is ideal for covering large conference rooms or
for capturing video of a specific area of interest
during a videoconference. Video data from each
camera can be sent as separate streams and
displayed on dual monitors, or the data can be
combined to form a single stream and viewed on a
- Data-Sharing Capabilities/Digital Whiteboard Support
Data originated on your PC can be shared with your
video conferencing counterparts, making
communication even more effective. Any image that
can be displayed on a PC can be sent or received in
native XGA resolution, allowing all parties to share
data during a video conference. In addition,
information drawn up on a digital whiteboard can
also be viewed in real time by all parties participating
in a video conference or captured and stored for later
- Easy-to-Use Remote Commander Unit/Intuitive GUI
The Sony PCS-G70 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 Sony PCS-G70 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
- Memory Stick Support
Private phone books can be created and stored on
Memory Stick media. By simply inserting the
Memory Stick media into the Sony PCS-G70, 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.
- Secure Video Conferencing -
Advanced Encryption Standard (AES)
Secure videoconferencing over a network is possible
because the Sony PCS-G70 supports AES Encryption, a NIST
(National Institute of Standards and Technology)
standard for encrypting electronic data used in
commercial applications including telecommunications.
When a video conference 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 video conference over a network, a
common concern is how to maintain video and audio
quality when the performance of the network is
changing. The Sony PCS-G70 provides three advanced
functions to enhance QoS over a network:
Forward Error Correction (FEC):
The PCS-G70 employs an FEC function that corrects
errors in transmission at the receiving end. If a
transmission error occurs, the PCS-G70 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.
Auto Repeat Request (ARQ):
The 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.
