摘要: Video coding standards, such as MPEG-4, H.264, and VC1, define hybrid transform based block motion compensated techniques that employ almost the same tools. This observation has been a foundation for defining MPEG Reconfigurable Multimedia Coding framework targets to facilitate multi-format codec design. The idea is send description of with bit stream, reconfigure tools accordingly on-the-fly. kind approach favors software solutions, substantial challenge implementers mobile multimedia devices aim at high energy efficiency. In particularly definition formats are about be required from devices, variable length decoders becoming serious bottleneck. Even current moderate video bitrates swallow major portion resources processor. this paper we present Transport Triggered Architecture (TTA) programmable implementation Context Adaptive Binary Arithmetic de-Coding (CABAC) used e.g. in main profile H.264 JPEG2000. solution can even other codes.
