Embodiment Construction
[0018] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0019] refer to image 3 , image 3 It is a flow chart of the steps of an embodiment of a method for reordering prediction residuals in video coding according to the present invention, including the following steps: step 110 of the reordering method is set, and the prediction residual blocks are set according to the amplitude distribution of the prediction residual blocks obtained by statistics reordering method, and all possible reordering methods of prediction residual blocks are two or more; reordering step 120, according to the reordering method of residual blocks obtained in the step of setting reordering method, in the residual Before the difference block is transformed, the residual values in the residual block are reord...
