摘要： Video data may be palette decoded. Data defining a palette table may be received. The palette table may comprise index values corresponding to respective colors. Palette index prediction data may be received and may comprise data indicating index values for at least a portion of a palette index map mapping pixels of the video data to color indices in the palette table. The palette index prediction data may comprise run value data associating run values with index values for at least a portion of a palette index map. A run value may be associated with an escape color index. The palette index map may be generated from the palette index prediction data at least in part by determining whether to adjust an index value of the palette index prediction data based on a last index value. The video data may be reconstructed in accordance with the palette index map.

摘要翻译： 视频数据可能被调色板解码。 可以接收定义调色板表的数据。 调色板表可以包括对应于各种颜色的索引值。 可以接收调色板索引预测数据，并且可以包括指示将调色板索引图的至少一部分映射到调色板表中的视频数据的像素与颜色索引的索引值的数据。 调色板索引预测数据可以包括将运行值与调色板索引图的至少一部分的索引值相关联的运行值数据。 运行值可能与转义颜色索引相关联。 调色板索引图可以至少部分地通过基于最后的索引值来确定是否调整调色板索引预测数据的索引值从调色板索引预测数据生成。 可以根据调色板索引图重建视频数据。
