本标准规定了D-11型压缩图片数据流到SDTI有效载荷区域（SMPTE 305.2M）的映射，以及AES3数据和时间码数据的四个通道到H-ANC数据包的映射。D-11型压缩图片数据流映射定义为源代码图片速率为24/1.001/P、24/P、25/P、50-I、30/1.001/P和60/1.001。对于以25/P和50/I的源图片速率编码的压缩图片数据的传输，SDTI接口以25 Hz的帧速率运行。对于以30/1.001P和60/1.001I的源图片速率编码的压缩图片数据的传输，SDTI接口以30/1.001 Hz的帧速率运行。

This standard specifies the mapping of type D-11 compressed picture data stream into the SDTI payload area (SMPTE 305.2M) together with the mapping of four channels of AES3 data and time code data into H-ANC packets. Type D-11 compressed picture data stream mapping is defined for source coded picture rates of 24/1.001/P, 24/P, 25/P, 50-I, 30/1.001/P, and 60/1.001. For the transmission of compressed picture data coded at source picture rates of 25/P and 50/I, the SDTI interface operates at a frame rate of 25 Hz. For the transmission of compressed picture data coded at source picture rates of 30/1.001P and 60/1.001I, the SDTI interface operates at a frame rate of 30/1.001 Hz.
