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
video.
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.
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 PRO
TM
and
Memory Stick DUO
TM
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.
