    • This disclosure describes techniques for generating a layered encoded bitstream structure that exploits correlation in header information among video blocks of a coded unit of video data. A video encoder configured to operate in accordance with the techniques of this disclosure separates header information of the video blocks of a slice (or other coded unit) from the residual information of the video blocks of the slice. The video encoder run length encodes the header information of the video blocks to better exploit the correlation of the header information among the blocks of the slice. After encoding the header information of the blocks of the slice, the video encoder encodes the residual information for each of the blocks of the slice. The video encoder transmits the encoded header information as a first sequence of bits and transmits the encoded residual information as second sequence of bits.
    • 本公开描述了用于生成分层编码比特流结构的技术,其利用视频数据的经译码单元的视频块之间的头信息中的相关性。 被配置为根据本公开的技术进行操作的视频编码器将切片(或其他编码单元)的视频块的标题信息与片的视频块的残差信息分开。 视频编码器运行长度对视频块的标题信息进行编码,以更好地利用片之间的标题信息的相关性。 在对切片的块的标题信息进行编码之后,视频编码器对切片的每个块的残差信息进行编码。 视频编码器将经编码的头信息作为第一比特序列发送,并将编码的残差信息作为第二比特序列发送。

    • This disclosure describes techniques for adaptively coding video block header information based on previously encoded video blocks. A video encoder may adaptively select a coding table for use in encoding a syntax element of a current video block based on corresponding syntax elements of one or more previously encoded blocks. In one aspect, the video encoder may adaptively select the coding table for use in encoding a block type of the current block based on block types of one or more video blocks adjacent to the current video block, i.e., neighboring video blocks. The video encoder may also predict one or more other header syntax elements of the current block based on at least one of the previously encoded video blocks. If prediction is successful, the video encoder may encode a flag to indicate the success of prediction.
    • 本发明描述用于基于先前经编码视频块自适应地译码视频块标头信息的技术。 视频编码器可基于一个或一个以上先前经编码块的对应语法元素自适应地选择用于编码当前视频块的语法元素的编码表。 在一个方面,视频编码器可基于与当前视频块相邻的一个或一个以上视频块(即,相邻视频块)的块类型自适应地选择用于编码当前块的块类型的编码表。 视频编码器还可基于先前经编码视频块中的至少一者来预测当前块的一个或一个以上其它标头语法元素。 如果预测成功,则视频编码器可编码标志以指示预测的成功。
