Claim 10:
11. An apparatus for video encoding, comprising:
processing circuitry configured to:
determine whether a plurality of constraint flags of a constraint information group is to be signaled for a subset of coding blocks,
signal a gate flag indicating whether the plurality of constraint flags of the constraint information group are signaled, wherein the gate flag is signaled in a general constraint information in a syntax structure of a coded video bitstream;
in accordance with the signaled gate flag indicating that the plurality of constraint flags of the constraint information group are signaled, signal the plurality of constraint flags of the constraint information group in the general constraint information syntax structure of the coded video bitstream;
based on the signaled plurality of constraint flags of the constraint information group, signal one or more offsets and one or more corresponding lengths, wherein each offset indicates a position of a set of contiguous constraint flags in the general constraint information syntax structure and a corresponding length indicates a number of constraint flags in the set of contiguous constraint flags in the general constraint information syntax structure; and
in accordance with the plurality of constraint flags being signaled in the general constraint information syntax structure, encode the subset of coding blocks based on the plurality of constraint flags.
