On October 30, 2013, Rowan Trollope from Cisco Systems announced that Cisco would release both binaries and source code of an H.264 video codec called OpenH264 under the Simplified BSD license, and pay all royalties for its use to MPEG LA themselves for any software projects that use Cisco's precompiled binaries (thus making Cisco's OpenH264 binaries free to use); any software projects that ...
It is H.264 and Dolby AC-3 packaged into the MPEG transport stream, with a set of constraints designed around camcorders. Developed jointly by Sony and Panasonic, the format was introduced in 2006 primarily for use in high definition consumer camcorders. [citation needed] Related specifications include the professional variants AVCCAM and NXCAM.
The H.264 specification calls H.261, H.262, H.263, and H.264 video coding standards and does not contain the word codec. [2] The Alliance for Open Media clearly distinguishes between the AV1 video coding format and the accompanying codec they are developing, but calls the video coding format itself a video codec specification .

The H.264 video format has a very broad application range that covers all forms of digital compressed video from low bit-rate Internet streaming applications to HDTV broadcast and Digital Cinema applications with nearly lossless coding. With the use of H.264, bit rate savings of 50% or more compared to MPEG-2 Part 2 are reported.
In H.264/AVC, P (predicted) and B (bipredicted) frames may contain I (intra) blocks, which store independent picture. Rather than create a slice in order to periodically refresh entirely with I or IDR frames, I-blocks can be sent in any desired pattern while predicted blocks make up the rest of the picture.

Context-adaptive binary arithmetic coding (CABAC) is a form of entropy encoding used in the H.264/MPEG-4 AVC [1] [2] and High Efficiency Video Coding (HEVC) standards. It is a lossless compression technique, although the video coding standards in which it is used are typically for lossy compression applications.
