Claim 4:
5. A method for encoding a picture into a video bitstream implemented by an encoding device, comprising:
encoding a value of first partition constraint information into a picture header of the video bitstream when a value of an override flag is an overriding value;
partitioning a block of a slice partitioned from the picture into a plurality of sub-blocks according to the value of the first partition constraint information;
encoding the override flag with the overriding value into the video bitstream;
partitioning the block of the slice into a plurality of sub-blocks according to a default value of the first partition constraint information when the value of the override flag is not the overriding value, wherein the default value of the first partition constraint information is a value of second partition constraint information; encoding the value of the second partition constraint information into a sequence parameter set (SPS) of the video bitstream; and encoding the override flag with a value different from the overriding value into the video bitstream.
