This article focuses on the development of the Advanced Audio Video Coding Standard in Information Technology (AVS) codec in China which started in June 2002, encouraging an alternative use for H.264 in consumer designs. This initiative is currently working in AVS 1.0. The standard is compatible with MPEG-2 at the system level. The biggest strength of AVS lies in its easy implementation. And from the coding perspective, H.264 requires more than twice the computing power of MPEG-2. For the same image quality, AVS requires about 30 percent less computing power than H.264. Moreover, the computing-power advantage that AVS offers arises from the granularity with which the scheme processes an image.
