Abstract (en)
[origin: WO0186961A1] According to a method for transformation-coding full motion image sequences, motion vectors are estimated in blocks and used to carry out motion compensation. The prediction error is transformation-coded. According to the invention, the block size of the transformation coding is coupled with the block size used for the motion compensation, respectively. This measure provides a means of increasing efficiency in the coding of the prediction error in hybrid coding methods that use different block sizes.
