Claim 15:
16. A non-transitory computer-readable recording medium storing a bitstream which is generated by a method performed by a video processing apparatus, wherein the method comprises:
determining a first indication for a first video block of a video, wherein the first video block is coded using an inter mode;
inferring, in response to the first indication indicating the first video block being divided into multiple first sub-blocks, a second indication for each first sub-block, wherein the second indication is not included in the bitstream and is inferred to indicate whether a luma component of a corresponding first sub-block includes non-zero coefficient values; and
generating the bitstream at least based on the second indication, and
wherein the multiple first sub-blocks comprise two first sub-blocks, wherein the second indication for one of the two first sub-blocks is derived to indicate that a luma component includes non-zero coefficient values, the second indication for another of the first two sub-blocks is derived to indicate that a luma component does not include non-zero coefficient values, and
wherein the second indication is inferred to be 1 to indicate that the luma component of the corresponding first sub-block includes non-zero coefficient values.
