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.

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 multi-
point 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.

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.
