Video recording - 12,65 mm type D-11 format - Part 3: Data mapping over SDTI 视频记录.12.65mm D-11型格式.第3部分:SDTI上的数据映射
发布日期: 2003-11-07
IEC 62356-3:2003规定了将D-11型压缩图片数据流映射到SDTI有效载荷区域(SMPTE 305.2M),以及将AES3数据和时间码数据的四个信道映射到H-ANC分组。D-11型压缩图片数据流映射定义为24/1001/P、24/P、25/P、50-I、30/1001/P和60/1001的源编码图片速率。对于以25/P和50/I的源图像速率编码的压缩图像数据的传输,SDTI接口以25Hz的帧速率操作。对于以30/1001P和60/1001I的源图像速率编码的压缩图像数据的传输,SDTI接口以30/1001Hz的帧速率操作。
IEC 62356-3:2003 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.
