Claim 9:
10. A decoder, comprising:
one or more processors; and
a non-transitory computer-readable storage medium coupled to the one or more processors and storing programming instructions for execution by the one or more processors, wherein the programming instructions, when executed by the one or more processors, configures the decoder to carry out operations comprising:
obtaining an override flag from the video bitstream, wherein the override flag indicates whether first partition constraint information is present in a picture header of the video bitstream;
when a value of the override flag is an overriding value, obtaining first partition constraint information for the slice from the picture header;
partitioning a block of the slice into a plurality of sub-blocks according to obtained value of the first partition constraint information;
when the value of the override flag is not the overriding value, partitioning the block of the slice into a plurality of sub-blocks according to a default value of the first partition constraint information, wherein the default value of the first partition constraint information is a value of second partition constraint information from a sequence parameter set (SPS) of the video bitstream; and
reconstructing the block of the slice by reconstructing the plurality of sub-blocks.
