本标准规定了用于表示ISO/IEC 13818-2 MPEG编码信息的与图片相关的记录数据集的内容，以便以任何比特率或GOP结构优化级联解码器和记录程序。如ISO/IEC 13818-2所述，编码信息在图片解码过程中从符合ISO/IEC 13818的MPEG比特流中导出。

This standard specifies the content of the picture related recoding data set for the representation of ISO/IEC 13818-2 MPEG coding information for the purpose of optimally cascading decoders and recoders at any bit rate or GOP structure. The coding information is as derived from an ISO/IEC 13818 compliant MPEG bit stream during the picture decoding process, as described in ISO/IEC 13818-2.
