Claim 12:
13. A non-transitory computer readable medium storing a bitstream containing encoded video data, the encoded video data to be generated by a process of:
encoding, into the bitstream, a profile syntax element indicating a target profile usable for decoding of the encoded video data among available profiles;
encoding, into the bitstream, a syntax element indicating a number of sub-profile usable for decoding of the encoded video data, each of sub-profile being different from the target profile in at least one of available coding tools;
encoding, into the bitstream, one or more sub-profile syntax elements based on said number of sub-profile, each of one or more sub-profile syntax elements indicating a respective sub-profile;
encoding, into the bitstream, constraint syntax elements for configurable coding tools included in any of the available profiles, at least one of the constraint syntax elements indicating whether a constraint is collectively imposed on several configurable coding tools, other of the constraint syntax elements indicating whether a constraint is imposed on a respective configurable coding tool;
encoding, into the bitstream, an enabled syntax element for each of the configurable coding tools, the enabled syntax element indicating whether to enable the respective configurable coding tool; and
setting whether to turn on/off target coding tools for a given sequence of the encoded video data,
wherein, when the constraint syntax element for a given target coding tool indicates that the constraint is imposed, the enabled syntax element for the given target coding tool is expected to indicate that the given target coding tool is not enabled.
