    摘要： A video coding device receives a bitstream including video data. The device determines an intra-prediction mode subset. The intra-prediction mode subset include intra-prediction modes that correlate to a plurality of reference lines for a current image block and excludes intra-prediction modes that correlate to a primary reference line for the current image block. When a first intra-prediction mode is included in the intra-prediction mode subset, the device decodes the first intra-prediction mode by an alternative intra-prediction mode index. When the first intra-prediction mode is not included in the intra-prediction mode subset, the device decodes the first intra-prediction mode by an intra-prediction mode index. The device presents video data including an image block decoded based on the first intra-prediction mode.

    摘要： 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.

    摘要： A coding apparatus including a memory, a processor, and a display is provided. The processor is configured to assign a first weight to a first reference pixel in a first neighbor block and a second weight to a second reference pixel in a second neighbor block. The first weight assigned to the first reference pixel is greater than the second weight assigned to the second reference pixel because the first reference pixel is closer to a third reference pixel than the second reference pixel. The processor is also configured to compute a value of the third reference pixel based on the first weight of the first reference pixel and the second weight of the second reference pixel, and generate a current block based on the value of the third reference pixel. The display is configured to display an image generated based on the current block.
