Abstract: The technology described herein facilitates parallel encoding of two groups of blocks of data of a sequence of blocks of data, whilst also facilitating the use of dependent encoding across the sequence of data blocks. This is achieved by allocating pairs of first and second groups of data blocks to separate encoding units, and determining an encoding parameter value to be used for encoding the first block of each second group of data blocks. For correct reconstruction of the image, it is ensured that a block belonging to the first group of data blocks of a pair of groups of data blocks is encoded with an encoding parameter value that will cause a decoder to use the determined encoding parameter value when decoding the first block of the second group.

Abstract translation: 这里描述的技术有助于数据块序列的两组数据块的并行编码，同时也有助于在数据块序列之间使用依赖编码。 这通过将第一组和第二组数据块分配给分离的编码单元并且确定要用于编码每个第二组数据块的第一块的编码参数值来实现。 为了图像的正确重建，确保属于一对数据块组的第一组数据块的块用编码参数值进行编码，该编码参数值将使解码器在解码时使用所确定的编码参数值 第二组的第一块。
