ITU-T H.263 Annex X (03/2004)

عربي | 中文 | English | Español | Français | Русский
Profiles and levels definition
This annex contains a list of preferred feature combinations, which are structured into "profiles" of support. It also defines some groupings of maximum performance parameters as "levels" of support for these profiles. This annex adds a new level (denoted level 45) to provide a conformance point with relatively low resolution but with higher bit rate support at that resolution than what was provided in the previously-defined levels. The new level also provides the capability to support low-resolution custom picture formats and custom picture clock frequencies.
