The High-End Sony PCS-G70S – Quality Visual Communications System with the Utmost in Flexibility

Videoconferencing 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 videoconferencing and developing systems that meet our customers' demands. The high-end PCS-G70S visual communications system is our latest solution to meet the needs of our power users.

The PCS-G70S 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-G70S produces image resolution comparable to that of standard TV broadcasts. It can also switch to the H.264 video codec for higher throughput and revert to previous versions of the ITU-T videoconferencing codecs to maintain compatibility with legacy systems.

As with other PCS Series models, the PCS-G70S, with its internal MCU (Multi-Control Unit) capability, supports simultaneous multi-point videoconferences with six (6) endpoints, and a maximum of 10 endpoints when two PCS-G70S units are cascaded. The PCS-G70S 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 PCS-G70S 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 with dual-stream support, which can be used to provide more video coverage. A unique feature that records audio and video to Memory Stick

media allows you to store accurate records of your videoconference. Still more useful tools include an optional tracking camera and a streaming capability.

The PCS-G70S also incorporates features such as data sharing, QoS support functions, an encryption function, and digital whiteboard support, which are all useful features for quality of videoconferencing.

As we enter a new era of visual communication, the feature-rich PCS-G70S will meet user needs for high-end and large-venue videoconferencing applications.

FEATURES

High-Quality Video/High-Speed Network Connection

The PCS-G70S 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-G70S 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-G70S 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.

The recommended camera for this system is the BRC-300, a 16:9/4:3 switchable 3CCD camera that provides exceptional quality video. Other optional cameras supported are the PCSA-CTG70 tracking camera and the PCSA-CG70 camera unit.

The PCS-G70SP supports a maximum of 50 fields per second in interlaced SIF format.

Multi-Point Videoconferencing at up to 10 Sites Fig 1

Using optional MCU software, the PCS-G70S 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-G70S 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-G70S 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-G70S 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-G70S allows users to expand from a peer-topeer videoconference to a multi-point videoconference by simply dialing up new connections.

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

Multiple Display Output

In addition to the main monitor output, the PCS-G70S can support up to five additional monitors that can be used to display the five other far-end sites in a 6-way videoconference.

Site-Name Display Fig 2

During multi-point videoconferences, it can be difficult to keep track of all of the participants; however, with the PCS-G70S site-name display function, this is no longer the case. The PCS-G70S can display anything from company or branch names to geographical locations on a monitor, allowing videoconference participants to keep track of all parties. This function is available both on a single monitor in continuous-presence mode and on multiple monitors.

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-G70S. Supporting both 4-screen and 6-screen continuous-presence modes, the PCS-G70S can display the most appropriate pattern to match the number of sites that are connected. In both full-screen and continuouspresence modes, the following two display options are available:

Voice Switching Fig 3

The PCS-G70S 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.
