Abstract: An exemplary method for visual media processing includes performing a conversion between a current video block of a visual media data and a bitstream representation of the visual media data in accordance with a conditional signaling rule. The current video block is disabled from using an intra sub-block partitioning (ISP) split mode which divides the current video block into sub-blocks depending on dimensions of the current video block. In case that the conversion is associated with disabling use of the ISP split mode, the conditional signaling rule specifies selectively including in the bitstream representation a first syntax element indicating that a luma component of a sub-block of the current video block includes non-zero coefficient values. The selectively including is based at least on one or more other syntax elements having non-zero coefficient values of one or more previous sub-blocks included in the bitstream representation.
