摘要
Adaptive compensation for requantization. A reference picture is decoded. Another copy of the reference picture is then requantized and then decoded. Next, an error picture is calculated and stored. The error picture represents the difference between the reference picture as decoded without requantization and the reference picture as decoded with requantization. The error picture and the requantized reference picture are used to generate a predictive picture that at least partially compensates for generational error introduced by requantization. This compensation for error may be adaptively performed based on system conditions.
