摘要：
A system for reducing storage requirements for content-adaptive binary arithmetic coding (CABAC) is provided. The system includes a transcode engine performing CABAC on a video data stream. The transcode engine receives save data, stops CABAC, and converts the video data stream into sub-network abstraction layer (NAL) unit state data. An entropy state data storage system receiving the sub-NAL unit state data and stores the sub-NAL unit state data. The transcode engine subsequently receives restore data, extracts the sub-NAL unit state data from the entropy state data storage system, and re-starts CABAC on the video stream data.
