Claim 19:
20. The non-transitory computer-readable storage medium of claim 16, wherein the method further comprises:
determining, for a second conversion between a second video block of the video and the bitstream of the video, a third indication, wherein the second video block is coded using an intra mode;
determining, in response to the third indication indicating the second video block being divided into multiple second sub-blocks, a fourth indication for each second sub-block, wherein whether the fourth indication for one of the multiple second sub-blocks is included in the bitstream is based on values of the fourth indications for other ones of the multiple second sub-blocks included in the bitstream; and
performing the second conversion at least based on the fourth indication, and
wherein the second indication for a last one of the multiple second sub-blocks is not included in the bitstream in response to the second indications for previous ones of the multiple second sub-blocks indicating the luma component does not include non-zero coefficient values,
wherein the second indication for the last one of the multiple second sub-blocks is derived to indicate that the luma component includes non-zero coefficient values,
wherein the second indication for the last one of the multiple second sub-blocks is inferred to be 1 to indicate that the luma component of the last one of the multiple second sub-blocks includes non-zero coefficient values,
wherein a size of the second video block is indicated by M*N, wherein M and N indicate a width and a height of the second video block, respectively,
wherein in response to M=4 N=8 or M=8 N=4, the second video block is divided into 2 second sub-blocks, or wherein in response to a product of M and N being greater than 32, the second video block is divided into 4 second sub-blocks, and
wherein all the second sub-blocks share a same intra mode.
