Polycom RMX 1000 Manual De Usuario

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. 

 

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. 

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 

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: 

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. 

Send Content to 
Legacy 
Endpoints 
 

When this option is enabled, legacy endpoints that do not 

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

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

these endpoints instead of the People video when Content is 

introduced to the conference. Legacy endpoints will not be able 

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.

 

 

To set the screen layout of conference on the endpoint screen, click the Video 
Settings tab on the New Profile interface.
