Claim 0:
1. A method of video decoding using at least one processor, the method comprising:
obtaining video data;
parsing the obtained video data to obtain partitioning parameters, wherein the partitioning parameters comprise a luma partitioning parameter corresponding to a luma component and one or more chroma partitioning parameters corresponding to a plurality of color components;
obtaining a partitioned super block based on the partitioning parameters;
determining whether the one or more chroma partitioning parameters are signaled separately or jointly based on at least one of a luma block area size of a smallest luma block of the partitioned super block and a luma splitting depth of the smallest luma block; and
decoding the video data based on a result of the determining,
wherein based on the luma block area size of the smallest luma block being larger than a first threshold, or the luma splitting depth of the smallest luma block being smaller than a second threshold, luma blocks of the partitioned super block and chroma blocks of the partitioned super block are partitioned based on a first block partitioning structure, and the one or more chroma partitioning parameters comprise a chroma partitioning parameter which is signaled jointly for the plurality of color components,
wherein based on the luma block area size being smaller than the first threshold, or the luma splitting depth of the smallest luma block being larger than the second threshold, the luma blocks of the partitioned super block are partitioned based on the first block partitioning structure, and the chroma blocks of the partitioned super block are partitioned based on a second block partitioning structure different from the first block partitioning structure, and the one or more chroma partitioning parameters comprise a plurality of chroma partitioning parameters which are signaled separately for the plurality of color components.
