Patent abstract
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. Specifically, the rate control method computes a target rate for a segment, where the segment comprises at least one slice of macroblocks. In turn, a target rate is computed for the at least one slice of macroblocks from the target rate for the segment. In turn, a quantization parameter (QPj) is computed for a macroblock (j) of the macroblocks from the target rate for the at least one slice. Finally, the macroblock (j) is encoded in accordance with said quantization parameter (QPj).
