H.264 is an international standard drafted by JVT organization covering multiple applications and for multiple transmission environments. It specifies three grades, Baseline profile, Main profile and Extended profile. The basic level uses I and P slices to support intra and inter coding, and supports entropy coding (CAVLC) using context-based adaptive variable length coding, mainly for conference television, video telephony, and wireless communication. Real-time video communication.

The AVS (Audio video coding) standard is an audio and video codec technical standard independently developed by China and possessing independent intellectual property rights. AVS-M (Mobile video) is the seventh part of the AVS series of standards - mobile video for digital storage media, broadband video services, remote monitoring and video telephony.
AVS-M and H.264 (Baseline) video decoders are very similar in structure, but each has its core idea. This paper analyzes the key technologies of the two decoders based on JM10.2 and WM3.3 source code. There is no separate H.264 (Baseline) code in the program, which is extracted from JM10.2. The following H.264 indicates that it is considered from the basic level.
