The PCS-G50 is a videoconferencing system that achieves high-quality video and audio. It is ideal for use in medium-sized conference rooms for a number of applications, such as corporate, education, and medical.


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. Optional PCSA-PRI (1.5Mbps ISDN) is supported.


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.

High-end videoconferencing system Codec Only model

High Speed Network Connection

The PCS-G70 with the powerful codec engine is capable to achieve Maximum 4Mbps bandwidth of IP connection that is currently the industry's highest level. For the ISDN connection, the PCS-G70 is the only model in PCS series supporting the PRI I/F of E1 (2Mbsp) / T1 (1.5Mbps).

 

High Resolution and Motion Video

The PCS-G70 supports the 4CIF format at Maximum 30fps in H.263 Video Encode Mode and the interlaced SIF format (60 fields per second) in H.264 Video Encode Mode. With this high resolution video encode modes at a high video bitrate such as 4Mbps the PCS-G70 will provide high video quality as standard TVs.

16:9 3CCD High Quality Camera Support

The PCS-G70 supports for the BRC-300 which is the 16:9 / 4:3 Switch-able 3CCD high quality camera. It can control BRC-300 in the same way as the standard camera regarding the Pan, Tilt and Zoom and etc. With the high quality video input from the BRC-300 and the powerful encoding capability the PCS-G70 will realize an excellent video.

High Quality Video and Audio in Multipoint Conference

The PCS-G70 can achieve the maximum 30 fps in the video encode, and supports H.264 video encode mode and MPEG4 AAC mono audio encode mode in the multi-point operation. Therefore high quality video and audio can be maintained even in multi-point conferences.

H.320/323 Bridging and Speed Matching

H.320/323 Bridging function is supported on the PCS-G70 in the same way as the PCS-1. In addition the PCS-G70 can accommodate two different speeds of the connections for H.320 and H.323 respectively. With this function it's possible to avoid lowering the speed of H.323 connection to match the H.320 connection. Thus the system performance can be maintained.

 

Five Monitor Out

 

The PCS-G70 supports 5 monitor out function to display each terminal site on an individual monitor up to 5 sites when it works as MCU. With this function good quality of video for the terminal site can be viewed at the MCU site.

 

Site Names Display

The PCS-G70 is capable to display the site names on the display even in the multi-way split display mode in multi-point conferences. This will greatly help the participants in multi-point conferences to understand the source of the video.

Dual Video Supported

The PCS-G70 supports the Dual Camera Input and H.239 Dual Video Stream function. These functions give the PCS-G70 a scalability to be applied to a larger scale conference room, a high quality boardroom and a class room in a higher grade school and so on.

Enhanced QoS

The PCS-G70 newly supports the FEC (Forward Error Correction) to enhance the QoS function in addition to the ARC (Adaptive Rate Control) and Real-time ARQ (Auto Repeat request). The PCS-G70 will utilize the above three methods simultaneously in an optimum ratio and maintain a very stable connection.
