| 用于H.300系列终端的扩展视频规程与控制信号 |
 |
本建议书规定了高级视频编解码器(包括ITU-T H.264建议书)在1TU-T H.310、H.320、H.321、H.322、H.323及H.324建议书终端中的使用。还为与在H.300系列终端中的所有视频编解码器一起使用定义了一般扩展信令。
本次修订版本增加的描述涉及关于H.264 VCL HRD(类型 I HRD)对比NAL HRD(类型 II HRD)比特率使用,关于H.264的取样宽高比能力,H.264 比特流的降低复杂度解码操作(RCDO)的信令,以及一个新的附件B,“用于H.264 基线类比特流的RCDO”。附件A已经由近期通过的参考文献RFC 3984(内容没有实际变化)中的内容所取代。新的附件B规定,当该使用已经采用ITU T H.241建议书商议后,降低复杂度解码操作将适用于H.264 基线类比特流。
