摘要： A lossless decoding unit 52 takes quantization parameters of decoded blocks spatially or temporally adjacent to a block to be decoded, as selection candidates, and extracts, from stream information, difference information indicating difference as to a prediction quantization parameter selected from the selection candidates. A quantization parameter calculating unit 59 calculates, from the prediction quantization parameter and the difference information, a quantization parameter of the block to be decoded. Thus, decoding of the image can be performed correctly by calculating a quantization parameter equal to a quantization parameter used at the time of image encoding.

摘要： A quantization level is determined for use by an encoder in encoding an image in accordance with a target number of bits. For each section of the image, the pixels are analyzed to estimate the complexity of the image section. For each of a plurality of candidate quantization levels, a relationship and the estimated complexity of the image sections are used to estimate the number of bits that would be generated by encoding the image with the encoder using the respective candidate quantization level, and based thereon one of the candidate quantization levels is selected. The relationship is a function of the quantization level used by the encoder, and is for use in relating the complexity of an image section to the number of bits that would be generated by encoding that image section with the encoder. The encoder uses the selected quantization level in encoding the image.

摘要： A system implements rate control for encoding and decoding operations, for example, operations performed on slices of data such as image data. The system implements a transformation from actual buffer fullness to rate controlled fullness. With the rate controlled fullness model, the encoders and decoders adapt bit allocation responsive to rate controlled fullness, instead of the actual fullness.

摘要： Embedded differential pulse code modulation (DPCM) is performed in response to coding locations of DPCM non-zero residuals during entropy coding utilizing adaptive run-length (ARL) coding. In this manner the need to code zero residuals is eliminated. After adaptive run-length coding, the non-zero residuals are coded in the regular mode, such as utilizing exponential Golomb coding. Overall compression is improved for blocks containing any significant number of zeros.

摘要： Disclosed herein are techniques and computer readable media containing instructions arranged to determine a bit allocation for a temporal base layer and at least one temporal enhancement layer. The techniques are enhanced to yield improved reproduced quality for the case where both a temporal base layer and at least one temporal enhancement layer is being used. An exemplary method for determining a bit allocation to one base layer includes initializing a bit allocation between the base layer and the at least one enhancement layer, determining a quality difference between the base layer and the at least one enhancement layer, expressed, for example, in the Quantizer Parameter of the last picture of each layer within a GOP, and determining a new bit allocation between the base layer and the at least one enhancement layer based on the quality difference and at least one constant factor.
