This standard specifies the coded representation of image information for digital storage media and digital video communications, and specifies the decoding process. This representation supports constant bit rate transmission, variable bit rate transmission, random access, channel switching, scalable decoding, bitstream editing, and special features such as fast forward, fast reverse, slow motion, and paused still images Function. This standard is forward compatible with GB/T 17191.2, and is upwardly or downwardly compatible with EDTV, HDTV, and SDTV formats. This standard is mainly used in digital storage media, video broadcasting and communication. The storage medium may be coupled to the decoder directly or via a communication facility such as a bus, LAN or telecommunication link.
