  • Fractional quantization parameter offset in video compression
    Patent number: 11019339
    Abstract: A method of coding includes receiving a bitstream, obtaining a chroma quantization parameter range offset, a luma quantization parameter, quantization parameter offsets, and coefficients; calculating first intermediate chroma quantization parameters using the chroma quantization parameter range offset, the luma quantization parameter, and the quantization parameter offsets; where the first intermediate chroma quantization parameters have non-integer values; determining second intermediate chroma quantization parameters based on the first intermediate chroma quantization parameters, where the second intermediate chroma quantization parameters have non-integer values; calculating final chroma quantization parameters based on the second intermediate chroma quantization parameters and the chroma quantization parameter range offset; calculating a quantization step using the final chroma quantization parameters; quantizing the coefficients using the quantization step to produce quantized coefficients and transformi

  • Noise suppression filter
    Patent number: 10623738
    Abstract: A mechanism of video coding is provided. The mechanism includes generating a reconstructed image from an encoded video stream. The reconstructed image is filtered to create a filtered image. The filtering includes applying a noise suppression filter to the reconstructed image. The noise suppression filter may be applied immediately prior to applying a deblocking filter to the reconstructed image, between a deblocking filter and a sample adaptive offset (SAO) filter, between the SAO filter and an adaptive loop filter, or after the adaptive loop filter. The filtered image is then stored in a picture buffer in memory for use in encoding or for output to a display in decoding.
