| 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. | ||
