摘要： A bit-plane coding scheme is described for the transform coefficient residues of the enhancement layer of a fine granularity scalability (FGS) scheme, e.g. as used in MPEG-4 video compression. In a first aspect, a determination is made as to the coding of the bit planes of the enhancement layer residues either in a fixed length code manner or in a variable length code manner based on the expectation value of the residue values of the bit planes not encoded. In another aspect, the encoding is applied to either the absolute values of the residues, or to the differences between the absolute values and an average of the absolute values, together with the signs of the differences.

摘要： A bit rate control scheme for video encoding is described, in which a target bitrate for a picture frame (or video object or macroblock) is determined based ona fluid-flow model of the buffer dynamics, and in which the buffer targetoccupancy is set to about 50% of a buffer safety margin used to determinewhether a frame should be skipped or not, the margin being about 80% of the buffer size. A new Rate-Distortion Model for determining a suitable quantizationparameter to give the target bit rate is also described, as is a sliding windowmethod of determining prior data points to update the Rate-Distortion modelparameters, and a switching frame-skipping control which switches between a predictive skipping control and a post frame skipping control.
