It has similar motion compensation, DCT transform and entropy coding with MPEG-1/2. 　 MPEG-4 MPEG-4 Visual Coding standard is standardized by ISO/IEC (International Standardization Organization/ International Electrotechnical Commission) based on H.263. However, MPEG-4 is more powerful with its better compression efficiency, higher error resiliency and scalability. 　 H.264/AVC H.264/ MPEG-4 Part 10 (AVC) is the latest video coding standard jointly developed by the VCEG (Video Coding Experts Group) of ITU-T and MPEG (Moving Picture Experts Group) of ISO/IEC. With same visual quality, PSNR (Peak Signal-to-Noise Ratio), H.264 offers 50% greater compression rate than H.263 and MPEG-4, and it removes transform mismatch between encoder and decoder. It also obtains network friendly structure and offers enhanced error concealment tool.
