IEC 62356-2:2011规定了将高清源格式压缩为双通道分组数据流格式，该格式适用于记录在包括D-11型磁带记录器在内的磁盘和磁带存储设备上。该规范包括许多基本的分组操作，包括压缩之前的源数据的混洗，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型分组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。它包括英文版的勘误表1（2011-05）。本标准的法语版本尚未表决。

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.
