| ITU-T H.300-系列终端的扩展视频程序和控制信号 |
ITU-T H.241建议书定义了包括ITU-T H.310、ITU-T H.320、ITU-T H.321、ITU-T H.322、 ITU-T H.323 和 ITU-T H.324 终端在内的ITU-T H.300系列终端根据ITU-T H.264建议书采用的先进视频调制解调器,它还定义了用于ITU-T H.300系列终端的所有视频调制解调器的通用扩展信令。本修订版本对前一版本做了一系列补充和说明。说明主要涉及第ITU-T H.264附件G可伸缩基线和可伸缩高剖面的描述,即选择可伸缩视频编码(SVC)视频流和ITU-T H.241功能的功能等级操作点的程序。本版本包括的ITU-T H.241(2006年) Amd. 1(2008年)提出的6.2.5款,为ITU-TH.264编码的具体视频子模式的磋商留出余地。它还通过纳入D8.2.2.14款定义了新的可选ITU-T H.264功能参数(MaxFPS)和包括说明第6.2.5款使用的非规范性实例。ITU-T H.241(2006年)Amd. 2(2009年)同时采用了第8.3.2.14款和附录2。 |
