Video Codecs

GAO provides the following video codecs:

Video codec for audiovisual services
Video coding for efficient communication over low data rate
Advanced video coding for generic audiovisual services
Video compression standard proposed by Motion Pictures Expert Group for digital television
Video compression standard proposed by Motion Pictures Expert Group for multimedia applications


GAO's H.261 software Video Codec supports real-time encoding and decoding of digital video frames. GAO's H.261 codec is designed to generate a bit stream to be transmitted over data links with capacities which are multiples of 64 Kbit/s. H.261 is sometimes referred to as a p x 64Kbit/s standard, where p is in the range of 1 to 30. GAO's fast and flexible implementation of H.261 is ideal for videoconferencing and video transmission applications.


GAO's H.263 software Video Codec for low bit-rate communication supports five different video resolutions. H.263 supports Sub-QCIF (SQCIF), 4CIF, and 16CIF in addition to QCIF and CIF that are supported by H.261. As a result, the codec could potentially compete with other higher bit-rate video coding standards such as the Motion Picture Experts Group (MPEG) standards for encoding high-resolution images.


GAO's H.264 software Video Codec is powerful, efficient, and has a robust format that is ideal for video applications. GAO's H.264 solution is optimized for the best possible quality. Below are some key features of GAO's H.264 codec:


GAO's MPEG-2 codec provides high bit rate video compression, HD video support and extensive encoding controls. GAO's codec is designed to meet demanding video encoding needs such as digital television. We provide our clients with a wide choice of encoding parameters and compression bit rates. This facilitates in getting precise control of the encoding/decoding process and, consequently, the flexibility to encode/decode content for a variety of applications.


This video codec forms the basis for developing applications and systems ranging from mobile multimedia to interactive digital television. GAO's implementation has been designed and optimized for porting to embedded processors and mapping on silicon architectures, and can also be used with mixed software/hardware solutions.

The Video codec is not only available for asymmetric applications like fixed or mobile receivers, but also for peer to peer applications like mobile video communication. Particular emphasis has been given to the processing and memory requirements, and ease of portability on different processors.
