Video Format | • Using the H.263 protocol, you can select one of |
(cont.) | the following options: Auto, QCIF, CIF, 4CIF, |
| 16CIF, VGA, SVGA, XGA and NTSC. |
| 4CIF - High Quality 4CIF video resolution available |
| in Continuous Presence conferences running at 512 |
| Kbps or higher line rates. In this mode, the endpoints |
| transmit CIF (or QCIF) and receive 4CIF images |
| from the MCU. In full screen layout (1x1), endpoints |
| that can send 4CIF images will also receive and |
| view 4CIF images from the MCU. |
| In 4CIF CP conferences, you can select the Quality |
| of the screen display depending on the video |
| transmission. For more information, see “Quality” on |
| page |
| NTSC (National Television Standards Committee) - |
| Each frame contains 525 lines and up to 16 million |
| colors. |
| VGA (Variable Graphics Array) - 640 x 480 |
| resolution |
| SVGA (Super Variable Graphics Array) - 800 x 600 |
| pixel resolution |
| XGA (eXtended Graphics Array) - 1024 x 768 pixel |
| resolution |
| VGA, SVGA, XGA and NTSC options are important |
| for displaying content when selecting the People and |
| Content mode. Typically the People resolution is CIF |
| with a frame rate of up to 30 frames per second, |
