Determination of quantization parameter (QP) value and delta QP value of palette coding block in video coding

摘要

Techniques for palette-based video coding are described. In palette-based coding, the video coder may form a so-called “palette” as a table of colors that represents the video data of a given block of video data. Rather than coding the actual pixel values of a given block or their residuals, the video coder may code the index value of one or more of the pixels. The index value maps a pixel to an entry in the palette that represents the color of the pixel. Techniques for determining the application of deblocking filtering for pixels of palette coded blocks in a video encoder or video decoder are described. In addition, techniques for determining quantization parameter (QP) values and delta QP values used to quantize escape pixel values of palette coded blocks in a video encoder or video decoder are described.
