IEC 62356-2:2011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型磁带录音机）上进行记录。该规范包括许多基本的打包操作，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在解码器中进行错误隐藏处理。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。该双语版本于2011-05年出版，与英文版本相对应。其中包括英文版的勘误表1（2011-05）。本标准的法文版尚未表决。

IEC 62356-2:2011 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 the 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. This bilingual version, published in 2011-05, corresponds to the English version. It includes corrigendum 1 (2011-05) to the English version. The French version of this standard has not been voted upon.
