Description

 

 

Dual Stream Mode

When an endpoint can support both H.239 and

(con’t)

People+Content protocols, H.239 is selected as the

 

preferred communications protocol.

 

In the Reservation Template Settings - Dual Stream

 

mode drop down box, three H.239 People+Content

 

(H.239/P+C) Video streaming formats are available:

 

Graphics - for standard graphics

 

Hi-res Graphics - for high quality display or highly

 

detailed graphics

 

Live Video - for video clips or live video display

 

128 Kbps is the minimum Line Rate setting for a

 

H.239/People+Content conference. When the

 

Content channel opens, the required bit rate is taken

 

from the video channel bit rate, and may affect the

 

quality of the transmitted video quality. The bit rate

 

allocated to the Content channel depends on the

 

conference type and the conference line rate, where

 

the minimum is 64 Kbps, and increases in multiple of

 

64 Kbps. The bite rate allocation is dynamic and

 

when the Content channel closes, the video bit rate

 

is restored to its maximum.
