    摘要： A method for decoding a video frame includes receiving a slice in a video decoder, identifying the slice as one of at least a first predicted slice and a second predicted slice, receiving information used to determine a context initialization method corresponding to the slice, and initializing, based on the received information, one of a first context initialization method and a second context initialization method associated with the slice, and decoding the video frame using the slice and one of the first context initialization method and the second context initialization method. The first context initialization method is a method for initializing a context associated with the first predicted slice and the second context initialization method is a method for initializing a context associated with the second predicted slice.

    摘要： An electronic device configured for high throughput binarization mode is described. The electronic device includes a processor and instructions stored in memory that is in electronic communication with the processor. The electronic device obtains a block of transformed and quantized coefficients (TCQs). The electronic device determines whether a high throughput binarization mode condition is met. If the condition is met, the electronic device uses the high throughput binarization mode to process the block. If the condition is not met, the electronic device does not use the high throughput binarization mode to process the block. The electronic device transmits the generated first or second bitstream to a decoder.

    摘要： A technique for decoding video including receiving quantized coefficient level values representative of a block of video representative of a plurality of pixels and a quantization parameter related to the block of video. The technique includes de-quantizing the quantized coefficient level values based upon the quantized coefficient level values and the quantization parameter only if the quantized coefficient level values and the quantization parameter are jointly within a predefined range of acceptable values. The technique also includes inverse transforming the dequantized coefficients to determine a decoded residue.

    摘要： A decoder decodes video received in a bitstream containing quantized coefficients representative of blocks of video representative of a plurality of pixels and a plurality of offset type characteristics. Each of the plurality of offset type characteristics is associated with a respective block of the video. A deblocking process deblocks the video to reduce artifacts proximate boundaries between the blocks of the video. A sample adaptive offset process classifies a pixel based upon the offset type characteristic associated with the respective block of the video, wherein the classification for a first offset type characteristic is based upon a first source of data and a second offset type characteristic is based upon a second source of data.

    摘要： A decoder receives a bitstream containing quantized coefficients representative of blocks of video representative of a plurality of pixels and decodes the bitstream using context adaptive binary arithmetic coding that includes at least two decoding modes, the first mode decoding the bitstream based upon a probability estimate which is based upon at least one of spatially and temporally adjacent syntax element values to a current syntax element being decoded, the second mode decoding the bitstream not based upon a probability estimate based upon other syntax elements to the current syntax element being decoded. The coding decodes the current syntax element using the first mode if the current syntax element is intra-coded and selecting between sets probable modes with different probabilities. The coding decodes the current syntax element using the second mode if the current syntax element is intra-coded and if selecting among one of the second set of probable modes.

    摘要： A method for tracking a reference picture on an electronic device is described. The method includes receiving a bitstream. The method also includes decoding a portion of the bitstream to produce a decoded reference picture.
