本标准规定了将高清源格式压缩为双通道打包数据流格式，该格式适用于在光盘和磁带存储设备（包括D-11型磁带记录器）上进行记录。该规范包括许多基本打包操作，包括在压缩之前对源数据进行洗牌，以帮助压缩性能并允许解码器中的错误隐藏处理。该标准还包括将压缩的D-11型打包数据格式解码为高清输出信号所需的过程。

This standard specifies the compression of a high-definition source format to a dual-channel packetized data stream format which is suitable for recording on disc and tape storage devices including type D-11 tape recorder. The specification includes a number of basic packetizing operations including the shuffling of the source data prior to compression both to aid compression performance and to allow error concealment processing in the decoder. The standard also includes the processes required to decode the compressed type D-11 packetized data format into a high-definition output signal.
