H264AVC
H.264/AVC, also known as H264AVC, is a video compression standard jointly developed by ITU-T Video Coding Experts Group (VCEG) and ISO/IEC JTC1/SC29/WG11 (MPEG). It was finalized in 2003 and is also designated as MPEG-4 Part 10. The standard provides high compression efficiency and flexibility to support a wide range of applications, from mobile video at low bitrates to high-definition broadcasts and storage formats such as Blu-ray Disc.
H.264 achieves its improved performance through several technical innovations. It uses block-based motion compensation with variable
The standard defines multiple profiles to balance complexity and capability. Baseline, Main, Extended, and High profiles
Applications and impact include widespread use in Blu-ray Disc, streaming services, digital television, and video conferencing.
Licensing for H.264 is patent-based, requiring appropriate licensing for implementations and deployments. See also H.265/HEVC and
