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.*1 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. *1 The PCS-G50P supports a maximum of 50
fields per second in interlaced SIF format. |

|
Multi-Point
Videoconferencing at up to 10 Sites |
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 multi-point videoconference. And of course, the
PCS-G50 allows users to expand from a peer-to-peer
videoconference to a multi-point videoconference. *2 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 |
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-in-picture 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 continuous-presence modes,
the following two display options are available: |
|
|
|
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 |
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 (TM) 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*3 directly to
Memory Stick media in MPEG-4 format and can be played back on
any PC using QuickTime media player. *3 AV recording is not
supported when AES is active. Also, graphical data cannot be
recorded. |
|
|
|
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*4 in native XGA
resolution, allowing all parties to share data during a
videoconference. In addition, information drawn up on a digital
whiteboard*5 can also be viewed in real time by all parties
participating in a videoconference or captured and stored for
later reference. *4 Sending data requires the optional
PCSA-DSB1S Data Solution Box (DSB); however, the DSB is not
required for receiving data *5 Please contact your local Sony sales office for information on compatible digital whiteboards. |

Superb Sound |
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 videoconference. 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. |

|
|
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 pre-programmed 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 contact. |
|
|
|
Memory Stick (TM)
Support*6 |
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. *6
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. |

|
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. |
