    • This disclosure relates to techniques for reducing the amount of additional data encoded with a block encoded using intra-predictive coding. Particularly, the techniques provide apparatus and methods of applying a smoothing filter to prediction samples used in intra-predictive coding. For example, in fixed mode-dependent intra- predictive coding, a video encoder may determine the type of smoothing filter applied to prediction samples based on block size and intra-prediction mode combination associated with the current block, where the combination is used to look up a filter in a first filter table. In adaptive mode-dependent intra-predictive coding, the encoder uses two filters, one from the first filter table and another from a second filter table, applies both filters, and determines which yields better results. When the second filter table filter yields better results, the encoder encodes a filtering indication. When a filter from the first filter table is used, no filtering indication is encoded.
    • 本公开涉及用于减少使用内部预测编码编码的块编码的附加数据的量的技术。 特别地,这些技术提供了将平滑滤波器应用于在帧内预测编码中使用的预测样本的装置和方法。 例如,在固定模式相关的帧内预测编码中,视频编码器可以基于与当前块相关联的块大小和帧内预测模式组合来确定应用于预测样本的平滑滤波器的类型,其中组合被用于查找 在第一个过滤器表中添加一个过滤器。 在自适应模式相关的内部预测编码中,编码器使用两个滤波器,一个来自第一个滤波器表,另一个来自第二个滤波器表,两个滤波器都应用两个滤波器,并确定哪个产生更好的结果。 当第二滤波器表滤波器产生更好的结果时,编码器对滤波指示进行编码。 当使用来自第一滤波器表的滤波器时,不对滤波指示进行编码。

    • A method for encoding transform coefficients in a video encoding process includes dividing a block of transform coefficients into a plurality of zones, determining a scan order for each of the plurality of zones, and performing a scan on each of the transform coefficients in each of the plurality of zones according to their respective determined scan order. In another example, a method for decoding transform coefficients in a video encoding process includes receiving a one-dimensional array of transform coefficients, determining a scan order for each of a plurality of sections of the one-dimensional array, wherein each section of the one-dimensional array corresponds to one of a plurality of zones defining a block of transform coefficients, and performing a scan on each of the transform coefficients in each of the section of the one dimensional array of zones according to their respective determined scan order.

    • This disclosure describes techniques for coding transform coefficients for a block of video data. According to these techniques, a video coder (a video encoder or video decoder) stores a first VLC table array selection table in memory, and an indication of at least one difference between the first VLC table array selection table and a second VLC table array selection table. The video coder reconstructs at least one entry of the second VLC table array selection table based on the first VLC table array selection table using the stored indication of the difference between the first VLC table array selection table and a second VLC table array selection table. The video coder uses the reconstructed at least one entry of the second VLC table array selection table to code at least one block of video data.
