H.264/AVC Compression Technology Overview

H.264/AVC is the latest block-oriented motion-compensation-based codec standard developed by the ITU-T Video Coding Experts Group (VCEG) together with the ISO/IEC Moving Picture Experts Group (MPEG), and it was the product of a partnership effort known as the Joint Video Team (JVT). H.264 is used in such application areas as:

• Broadcasing. The Digital Video Broadcast project (DVB) approved the use of H.264/AVC for broadcast television in late 2004.
• The CCTV (Close Circuit TV) or Video Surveillance market has included the technology in many products. Starting in 2008, some in the surveillance industry promoted the H.264 technology as synonymous with "high quality" video.
• Web players and YouTube-like video sharing services
• Optical disc storsge - Blue-ray
