AVS is a possible alternative codec to H.264/AAC/Vorbis ^[1] and is meant to potentially replace MPEG-2. China companies own 90% patents of AVS. ^[1]^[2] The audio and video files have an .avs extension as a container format, and the designers claim that it will have twice the efficiency of MPEG2.^{[citation needed]}

In January 2005, the AVS workgroup submitted their draft report to the Information Industry Department (IID). On March 30, 2005, the first trial by the IID approved the video portion of the draft standard for a public showing time.
