    摘要： A method of video encoding is provided that includes performing context-adaptive binary arithmetic coding (CABAC) on a plurality of syntax element values in a slice to generate a plurality of entropy-encoded syntax element values, generating an entropy slice header to identify the plurality of entropy-encoded syntax element values as an entropy slice, wherein the entropy slice header comprises context model initialization information, and outputting the entropy slice header and the plurality of entropy encoded syntax element values.

    摘要： A method of video decoding is provided that includes receiving a data stream comprising a sequence of syntax elements that were compressed using context-adaptive binary arithmetic coding (CABAC), such that the encoding of each bin of a bin string representative of a syntax element was performed by arithmetic encoding. Two consecutive bins of a syntax element are decoded in parallel. Speculative computation and prefetching is used to reduce the critical path and thereby improve processing speed.

    摘要： An encoded bitstream of entropy encoded video data is received by a video decoder. The encoded bitstream represents syntax elements of a sequence of coding blocks. The sequence of coding blocks is recovered by processing a bin sequences associated with each coding block in a processing pipeline, wherein a defined amount of time is allocated to process each coding block in the processing pipeline. The encoded bitstream is arithmetically decoded to produce each bin sequence. The arithmetic decoder is time-wise decoupled from the processing pipeline by storing a plurality of the bin sequences in a buffer memory.

    摘要： A method of encoding an image frame in a video encoding system. The image frame has a region of interest (ROI) and a non region of interest (non-ROI). In the method, quantization scale for the image frame based on rate control information is determined. ROI statistics based on residual energy of the ROI and non-ROI is then calculated. Quantization scale for the image frame based on ROI priorities and ROI statistics is calculated. Further, quantization scales for ROI and non-ROI based on ROI priorities are determined.
