H.264/AVC Video Compression

H.264/AVC is the new video coding standard developed by the Joint Video Team (JVT) of ISO/IEC MPEG and ITU-T Video Coding Expert Group (VCEG). Compared to MPEG-2, MPEG-4, and H.263, the new standard aims at better compression efficiency, more flexible network adaption, and enhanced error robustness. The H.264/AVC is similar to preceeding standards in its use of a block transform. A new feature of this design is its introduction of a separation between a video coding layer (VCL), which provides the high-compression representation of the video picture content, and a Network Adaption Layer (NAL), which packages that representation for delivery over a particular type of network.

PixSil's Configurable Solution

PixSil has developed H.264/AVC codec solutions based on a configurable and scalable architecture that supports the wide-ranging requirements in consumer multimedia products.

• Flexible and configurable architecture: the functions are tuneable for area, power, and performance
• Scaleable and adaptable architecture: to meet different bit rates, frame rates, and resolutions (QCIF, CIF, SIF, 4CIF, 4SIF, NTSC SD)
• Algorithmic flexibility: able to support different profiles by adding or replacing functional blocks
• Supports varying user requirements: able to support different requirements, e.g. bus interface or error concealment methodology, by substituting functional blocks
• System scalability: able to configure the SOC as a multi-channel system with multiple cores
