摘要： Techniques are described for palette-based video coding. In palette-based coding, a video coder may form a "palette" as a table of colors for representing video data of a particular area. Rather than coding actual pixel values (or their residuals), the video coder may code palette index values for one or more of the pixels that correspond to entries in the palette representing the colors of the pixels. A palette may be explicitly encoded, predicted from previous palette entries, or a combination thereof. In this disclosure, techniques are described for coding a block of video data that has a single color value using a single color mode as a sub-mode of a palette coding mode. The disclosed techniques enable a block having a single color value to be coded with a reduced number of bits compared to a normal mode of the palette coding mode.
摘要翻译：描述了基于调色板的视频编码技术。在基于调色板的编码中，视频编码器可以形成“调色板”作为用于表示特定区域的视频数据的颜色表。视频编码器不必对实际像素值（或其残差）进行编码，而是可以对与表示像素的颜色的调色板中的条目相对应的一个或多个像素编码调色板索引值。调色板可以被显式编码，从先前调色板条目预测或其组合。在本公开中，描述了用于使用单色模式将具有单一颜色值的视频数据块编码为调色板编码模式的子模式的技术。与调色板编码模式的正常模式相比，所公开的技术使具有单个颜色值的块以减少的位数被编码。

摘要： Techniques are described for palette-based video coding. In palette-based coding, a video coder may form a so-called "palette" as a table of colors for representing video data of a given block of video data. Rather than coding actual pixel values or their residuals for the given block, the video coder may code index values for one or more of the pixels. The index values map the pixels to entries in the palette representing the colors of the pixels. Techniques are described for determining the application of deblocking filtering for pixels of palette coded blocks at a video encoder or a video decoder. In addition, techniques are described for determining quantization parameter (QP) values and delta QP values used to quantize escape pixel values of palette coded blocks at the video encoder or the video decoder.

摘要： Techniques are described for palette-based coding. In palette-based coding, a video coder may form a palette as a table of colors for representing video data of a given block. Palette-based coding may be useful for coding blocks of video data having a relatively small number of colors. Rather than coding actual pixel values or their residuals for the given block, the video coder may code index values for one or more of the pixels. The index values map the pixels to entries in the palette representing the colors of the pixels. Techniques are described for determining whether to disable filtering, such as deblocking filtering or sample adaptive offset (SAO) filtering, of palette coded blocks at a video encoder or a video decoder. Techniques are also described for modify a palette size and palette entries of a palette at the video encoder based on rate-distortion costs.

摘要： In general, this disclosure describes techniques for coding video blocks using a color-space conversion process. A video coder, such as a video encoder or a video decoder, may determine a bit-depth of a luma component of the video data and a bit-depth of a chroma component of the video data. In response to the bit-depth of the luma component being different than the bit depth of the chroma component, the video coder may modify one or both of the bit depth of the luma component and the bit depth of the chroma component such that the bit depths are equal. The video coder may further apply the color-space transform process in encoding the video data.
