摘要： A method for determining quantization parameters is provided. The method includes determining one or more first units of video content in a grouping of units and analyzing whether the one or more first units of video content within a region in the grouping of units have coefficients for the video content that are zero. The method then determines whether a quantization parameter for one or more second units of video content different from the one or more first units of video content is to be used to derive the quantization parameter for the one or more first units of video content. When the quantization parameter for the one or more second units of video content is to be used, the quantization parameter for the one or more first units of video content is derived from the quantization parameter for the one or more second units of video content.

摘要： The present invention discloses a system and method for providing a rate control to an encoder, e.g., a H.264/MPEG-4 AVC compliant encoder (1). Specifically, the rate control method computes a target rate for a segment, where the segment comprises at least one slice of macroblocks (130). In turn, a target rate is computed for the at least one slice of macroblocks from the target rate for the segment (130). In turn, a quantization parameter (QP j ) is computed for a macroblock (j) of the macroblocks from the target rate for the at least one slice (170). Finally, the macroblock (j) is encoded (180) in accordance with said quantization parameter (QP j ).

摘要： A system includes an encoder that performs quantization on a rectangular block of quantized transform coefficients and a decoder that performs dequantization on a rectangular block of transform coefficients. The decoder is configured to receive a WxH block of quantized transform coefficients, wherein W is a row width of the block and H is a column height of the block. The decoder is further configured to apply dequantization processing to the WxH block of quantized transform coefficients to generate a block of transform coefficients, which are used to generate a picture corresponding to the WxH block of quantized transform coefficients. The dequantization processing comprises applying a first dequantization algorithm when an output M of a function (I) is equal to an integer value, and applying a second dequantization algorithm when the output M is equal to a non-integer value.
