摘要： A system and method for video/image encoding and decoding, where transform coefficients associated with a plurality of blocks are reorganized and coded together. Various embodiments perform transform and quantization and generate transform coefficients, where the coefficients of the transform blocks are reorganized and interleaved. Additionally, an encoding process involves coding only a subset of the transform coefficients belonging to the transform blocks resulting in one or more transform blocks less than the original number of transform blocks, and putting this into a bitstream. A decoding process involves decoding the one or more resulting transform blocks including the subset of transform coefficients from the bistream, the transform coefficients being put in an array and decoded. The decoder de-interleaves the decoded transform coefficients and any remaining coefficients of the one or more transform blocks are filled in according to a plurality of different methods. After the one or more transform blocks are fully decoded, inverse transform and inverse quantization are performed and residual data is generated.
摘要翻译：一种用于视频/图像编码和解码的系统和方法，其中与多个块相关联的变换系数被重组和编码在一起。各种实施例执行变换和量化并生成变换系数，其中变换块的系数被重组和交织。此外，编码处理涉及仅编码属于变换块的变换系数的子集，导致小于原始数量的变换块的一个或多个变换块，并将其放入比特流中。解码过程涉及对来自双向头的变换系数子集的一个或多个所得到的变换块进行解码，将变换系数置于阵列中并进行解码。解码器解交织解码的变换系数，并且根据多种不同的方法填充一个或多个变换块的任何剩余系数。在一个或多个变换块完全解码之后，执行逆变换和逆量化，并产生残差数据。

摘要： Transform coding is not restricted inside normal block boundary but is adjusted to the characteristics of the prediction error. Thereby it is possible to achieve a coding efficiency improvement by selecting and coding the best portion of the prediction error in terms of rate distortion tradeoff.
