Abstract:
A video decoder comprising a first comfort noise addition block and a second comfort noise addition block. The first comfort noise addition block may be configured to (i) add comfort noise to luminance data and (ii) adjust a distribution of the comfort noise added to the luminance data. The second comfort noise addition block may be configured to (i) add comfort noise to chrominance data and (ii) adjust a distribution of the comfort noise added to the chrominance data. The first and the second comfort noise addition blocks may be integrated into a video output path of the video decoder. The distribution of the comfort noise added to the luminance data and the distribution of the comfort noise added to the chrominance data may be adjusted independently.
