摘要:
A system for decoding video including receiving quantized coefficients representative of a block of video representative of a plurality of pixels and dequantizing the quantized coefficients. Inverse transforming the dequantized coefficients to determine a decoded residue wherein the dequantized coefficients are modified prior to the inverse transforming based upon a predicted dynamic range output of the inverse transform.
