Abstract
A method for encoding a video sequence in a video encoder is provided that includes adapting a quantization parameter of a block of pixels in a picture of the video sequence based on a transform block size of the block of pixels to determine a final quantization parameter, and quantizing transform coefficients of the block of pixels using the final quantization parameter.
Claims15
A method for encoding a video sequence in a video encoder, the method comprising:
- adapting a quantization parameter of a block of pixels in a picture of the video sequence based on a transform block size of the block of pixels to determine a final quantization parameter;
- and
- quantizing transform coefficients of the block of pixels using the final quantization parameter.
An apparatus for encoding a video sequence, the apparatus comprising:
- means for adapting a quantization parameter of a block of pixels in a picture of the video sequence based on a transform block size of the block of pixels to determine a final quantization parameter;
- and
- means for quantizing transform coefficients of the block of pixels using the final quantization parameter.
A non-transitory computer readable medium storing software instructions that, when executed by a processor, cause a method for encoding a video sequence to be performed, the method comprising:
- adapting a quantization parameter of a block of pixels in a picture of the video sequence based on a transform block size of the block of pixels to determine a final quantization parameter;
- and
- quantizing transform coefficients of the block of pixels using the final quantization parameter.
