Polycom RMX 1000 User Guide

and the conference video can be displayed with the best HD resolution of 1280x720 (720p). However, all the endpoints must support the H.264 protocol and 720p resolution, and the bandwidth cannot be lower than 832Kbps, or else the display of conference video will be, depending on the capability of the participant's endpoint, degraded to the resolution of 4CIF or CIF, or H.263 code.

The RMX supports a maximum of 20 video resources and 20 audio resources. The number of connection resources supported by the device in the actual conference depends on the number of resources purchased by the user.

Defining Content Video Quality

When the endpoint sends dual streams, the RMX 1000 system applies different encoding and decoding policies to the people video stream and content video stream. See the table below, which provides the video parameters for setting the second channel of content image.

Table 4-8Video Quality Parameters – Second-channel Video Dual-stream Definition

Parameter

Description

 

Set the video protocol used for the dual-stream video. You can

 

select the H.264 or H.263 coding/decoding algorithm based on

 

the endpoint capability and network bandwidth. When None is

Content Setting

selected, it indicates dual streams are not enabled.

Note: If this setting is H.264, when an endpoint that only

 

 

supports H.263 protocol joins in the conference, an H.264

 

endpoint that originally sent dual streams will terminate sending

 

dual streams and resend them using the H.263 protocol.

 

 

 

The H.239 protocol is used to send dual streams. You can

 

select three kinds of video quality as needed:

H.239 Setting

ƒ Graphics: For the standard video display

ƒ High-resolution graphics: For the graphic detail display of high

 

quality broader bandwidth is required.

 

ƒ Live Video: For full-motion of dynamic video display. The

 

broadest bandwidth is required.

 

 

 

When this option is enabled, legacy endpoints that do not

 

support the H.239 protocol will still be able to view Content in

Send Content to

the conference. However, the Content video will be sent to

these endpoints instead of the People video when Content is

Legacy

introduced to the conference. Legacy endpoints will not be able

Endpoints

to share content – they will only be able to view. Modern

 

 

endpoints which support H.239 will continue to view dual

 

streams (People and Content simultaneously) and be able to

 

share content.
