Claim 6:
7. A device for video coding, the device comprising:
at least one memory configured to store program code; and
at least one processor configured to read the program code and operate as instructed by the program code, the program code including:
first obtaining code configured to cause the at least one processor to obtain video data;
parsing code configured to cause the at least one processor to parse 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;
second obtaining code configured to cause the at least one processor to obtain a partitioned super block based on the partitioning parameters;
determining code configured to cause the at least one processor to determine 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 code configured to cause the at least one processor to decode the video data based on the partitioned super block,
wherein based on the luma block area size 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, and
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.
