Abstract:
Aspects of the disclosure provide a method and an apparatus for video coding. In some embodiments, the apparatus includes processing circuitry. The processing circuitry decodes encoding information associated with a block of a picture in a coded video bitstream. The encoding information indicates a position of a sub-region in the block, and an area of the sub-region is ¼ of an area of the block. The processing circuitry further reconstructs first samples of the block that are inside the sub-region using residual data of the first samples, and reconstructs second samples of the block that are outside of the sub-region without residue data.

Claim (Index 18):
The apparatus of  claim 12 , wherein\n the encoding information further indicates a position of an additional sub-region in each of at least one neighboring block of the block; a combined sub-region including the sub-region and the additional sub-region in each of the at least one neighboring block is at a center of a combined block including the block and the at least one neighboring block; the combined sub-region and the combined block have a rectangular shape, a width ratio of a width of the combined sub-region over a width of the combined block being equal to a first ratio, a height ratio of a height of the combined sub-region over a height of the combined block being equal to a second ratio; and the processing circuitry is configured to: implement an inverse transform on transform coefficients of the first samples and third samples inside the combined sub-region to determine residue data of the first and third samples inside the combined sub-region, the transform coefficients of the first and third samples being included in the coded video bitstream, the third samples being inside the additional sub-region in each of the at least one neighboring block; reconstruct the third samples using the residue data of the third samples; and reconstruct fourth samples of the at least one neighboring block that are outside of the additional sub-region without residue data.
