摘要： Innovations in flexible reference picture management are described. For example, a video encoder and video decoder use a global reference picture set ("GRPS") of reference pictures that remain in memory, and hence are available for use in video encoding/decoding, longer than conventional reference pictures. In particular, reference pictures of the GRPS remain available across random access boundaries. Or, as another example, a video encoder and video decoder clip a reference picture so that useful regions of the reference picture are retained in memory, while unhelpful or redundant regions of the reference picture are discarded. Reference picture clipping can reduce the amount of memory needed to store reference pictures or improve the utilization of available memory by providing better options for motion compensation. Or, as still another example, a video encoder and video decoder filter a reference picture to remove random noise (e.g., capture noise due to camera imperfections during capture).
摘要翻译：描述了灵活的参考图片管理的创新。例如，视频编码器和视频解码器使用保留在存储器中的参考图片的全局参考图片集（“GRPS”），并且因此可用于视频编码/解码，比传统参考图片更长。具体而言，GRPS的参考图片在随机访问边界上保持可用。或者，作为另一示例，视频编码器和视频解码器剪切参考图片，使得参考图片的有用区域被保留在存储器中，而参考图片的无用或冗余区域被丢弃。参考图片裁剪可以减少存储参考图片所需的内存量，或通过提供更好的运动补偿选项来提高可用内存的利用率。或者，作为又一示例，视频编码器和视频解码器对参考图片进行滤波以去除随机噪声（例如，捕获期间由于相机瑕疵造成的捕获噪声）。

摘要： Innovations in the area of encoding or decoding of blocks using intra block copy prediction improve coding efficiency for intra-BC-predicted blocks in many situations. For example, some of the innovations relate to block flipping in which an intra-BC-predicted block is flipped relative to a reference region, which can be indicated by a block vector value. Other innovations relate to signaling of a skip mode in which a current intra-BC-predicted block uses a signaled BV differential but lacks residual data.

摘要： Innovations in intra-picture prediction with multiple candidate reference lines available are described herein. For example, intra-picture prediction for a current block uses a non-adjacent reference line of sample values to predict the sample values of the current block. This can improve the effectiveness of the intra-picture prediction when the reference line of sample values that is adjacent the current block includes significant capture noise, significant quantization error, or significantly different values (compared to the current block) due to an occlusion. Innovations described herein include, but are not limited to, the following: intra-picture prediction with multiple candidate reference lines available; encoding/decoding of reference line indices using prediction; filtering of reference sample values; residue compensation weighted prediction; mode-dependent padding to replace unavailable reference sample values; using in-loop-filtered reference sample values; encoder-side decisions for selecting reference lines; and post-filtering of predicted sample values.
摘要翻译：本文描述了具有可用的多个候选参考线的图片内预测的创新。例如，当前块的图片内预测使用非相邻的样本值参考线来预测当前块的样本值。当邻近当前块的样本值的参考线包括明显的俘获噪声，显着的量化误差或由于遮挡引起的明显不同的值（与当前块相比）时，这可以改进画面内预测的有效性。本文描述的创新包括但不限于以下：具有可用的多个候选参考线的画面内预测; 使用预测对参考线索引进行编码/解码; 过滤参考样本值; 残差补偿加权预测; 模式相关的填充来替换不可用的参考样本值; 使用经环路滤波的参考采样值; 用于选择参考线的编码器端决策; 并对预测样本值进行后期过滤。

摘要： Various innovations facilitate the use of intra-picture prediction modes such as palette prediction mode, intra block copy mode, intra line copy mode and intra string copy mode by an encoder or decoder when wavefront parallel processing ("WPP") is enabled. For example, for a palette coding/decoding mode, an encoder or decoder predicts a palette for an initial unit in a current WPP row of a picture using previous palette data from a previous unit in a previous WPP row of the picture. Or, as another example, for an intra copy mode (e.g., intra block copy mode, intra string copy mode, intra line copy mode), an encoder enforces one or more constraints attributable to the WPP, or a decoder receives and decodes encoded data that satisfies one or more constraints attributable to WPP.

摘要： Innovations in the use of base color index map ("BCIM") mode during encoding and/or decoding simplify implementation by reducing the number of modifications made to support BCIM mode and/or improve coding efficiency of BCIM mode. For example, some of the innovations involve reuse of a syntax structure that is adapted for transform coefficients to instead signal data for elements of an index map in BCIM mode. Other innovations relate to mapping of index values in BCIM mode or prediction of elements of an index map in BCIM mode. Still other innovations relate to handling of exception values in BCIM mode.
