The encoder circuit may be configured to generate a plurality of coefficient values and motion vectors in response to a video stream, a first control signal, a second control signal, and a number of quantized values. The control circuit may be configured to (i) generate the first control signal, the second control signal, and a quantizer index signal and (ii) set two or more quantization dead zones and two or more offsets to different values, where the quantization dead zones and the offsets are independently programmable. The quantizer circuit may be configured to generate the number of quantized values in response to the coefficient values, the quantizer index signal, the two or more quantization dead zones and the two or more offsets. A first coefficient value may be quantized using a first quantization dead zone and a first offset. A second coefficient value may be quantized using a second quantization dead zone and a second offset. The first and second quantization dead zones generally have different values. The first and second offsets generally have different values. Quantization calculations determining each quantized value take into account respective quantization dead zones and offsets.

    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.
