Sony PCS-G70P Specifications page 4

■ Flexible Display Patterns at all Sites
The PCS-G70P offers a range of flexible display options, allowing
you to customize the look of any conference to suit your precise
needs and the number and positioning of connected display
monitors. It can show far side participants as a full-screen view,
or alternatively display near-side and far-side sites simultaneously
as a picture-in-picture mode. Four-screen and six-screen
continuouspresence modes are also supported for the most
appropriate display format to match the number of connected sites
that are. In both full-screen and continuous-presence modes, two
display options are available:
Voice Switching
Voice switching mode in a six-screen (or 5+1 screen layout) displays
the active speaker as the largest on-screen inset, with the other five
participants grouped around them as smaller images. When the
active speaker changes, they are automatically 'promoted' to be
the largest displayed inset picture, while the previous speaker
re-joins the other smaller picture insets.
Fixed Site

The selected far-side participant is continuously displayed on the
monitor when the unit is in full-screen mode. In continuous-presence
mode, the selected far-side site is displayed in the largest of the six
inset sub screens.
■ Multiple Display Output
In addition to its main monitor output, the PCS-G70P can support
up to five additional monitors to display pictures from far-side sites
in a six-way videoconference.
■ Dual Camera and Split Picture Support
The PCS-G70P can be configured to handle simultaneous video
streams from two cameras, making it an ideal solution for providing
coverage of large conference rooms or for capturing video of a
specific area of interest during a videoconference, such as a
closeup of a surgical procedure. Video from each camera can be
displayed on dual monitors, or alternatively pictures can be
combined and viewed on a single monitor as a 'split screen' image.
A total of four cameras or other video sources such as a DVD player
or VCR can be connected to the PCS-G70P. During a conference,
users can switch dynamically between video sources and choose
between sending either one or two sources at the same time to
other participants.

■ Data-Sharing Capabilities/Digital Whiteboard
Support
With the optional PCSA-DSB1S Data Solution Box, two PC's or
notebooks can be connected simultaneously to send graphics and
documents for sharing with other conference participants. These
powerful data sharing capabilities make communications more
effective in wide range of business, education and scientific
applications. Word processing documents, spreadsheets,
presentations or digital artwork can be displayed* in native XGA
resolution.
Further improving the natural interactivity of a face-to-face meeting,
an optional Mimio Xi™** connected to the PCS-G70P turns your
existing whiteboard into a digital one, allowing handwritten notes,
drawings and diagrams to be displayed in real time. Notes and
other annotations can also be captured by the PCS-G70P and
stored to the Memory Stick™ for sharing, storage or wider
distribution.
* Sending data requires the optional PCSA-DSB1S Data Solution Box which is
however not required for receiving data.
** Please contact your local Sony sales office for information on compatible digital
whiteboards.
■ Superb Sound Quality
The PCS-G70P provides exceptionally clear, natural-sounding
audio. Wideband audio processing for point-to-point and multipoint
conferences uses the MPEG-4 AAC (Advanced Audio Coding)
standard, whether using IP, ISDN or mixed IP/ISDN networks. The
built in echo cancellation and noise reduction system ensures
improved intelligibility by minimizing the distraction of unwanted
echoes during conferences. The PCS-G70P is also compatible with
a wide range of Sony external microphones and speakers,
speakers, for greater flexibility.
■ Stylish Design
The sleek, discreet lines of the main processor and camera units
make the PCS-G70P an elegant complement to any boardroom or
auditorium. The processor itself can be mounted horizontally or
vertically (NB: vertical mounting requires optional Codec Stand).
Each camera can be sited on a stylish eye-level stand, and cameras
can respond to commands from the supplied IR Remote
Commander.
■ QoS (Quality of Service) Enhancement Functions
Consistent audio and video performance in the face of changeable
network conditions is a common concern with videoconferencing
systems. The PCS-G70P offers three advanced functions to
enhance Quality of Service over any network connection. These can
be used in 'hybrid' mode, combining the strengths of each
mechanism to assure the best possible audio and video quality,
even under changing IP network conditions:
Forward Error Correction (FEC)
The powerful Forward Error Correction (FEC) function corrects
transmission errors at the receiving end, repairing corrupted data to
ensure that audio and video is accurately reproduced.
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, reducing the risk of audio
and video breakup.
