Dual Stream Mode | In this mode, one of the endpoints sends two video |
| streams: Video and data. The video streams are |
| handled differently by the receiving endpoint. The |
| different streams may be shown on separate |
| screens. |
| Select one of the following options: |
| None - The Dual Video mode is unavailable. In |
| such a case Video Protocol is set to Auto. |
| H.239 and People+Content - H.239 and |
| People+Content are very similar in function, but |
| differ in the type of signaling used for each |
| protocol. People+Content is the Polycom |
| proprietary protocol while H.239 is the industry |
| standard. When an endpoint can support both |
| H.239 and 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 |
| |
| 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. |
| People+Content in a Cascading conference is |
| enabled only for Video Switching IP Only |
| conferences, in a Star Cascaded topology. |
