Claim 11:
12. A non-transitory computer-readable storage medium comprising processor executable code for a programmable apparatus, comprising a sequence of instructions for implementing a method of decoding video data comprising a frame from a bitstream, the frame being spatially divided into rectangular regions each of which is capable of comprising at least one slice, the method comprising:
obtaining, from a single parameter set in the bitstream, an identifier of each one of the rectangular regions in the frame, a position of a frame portion in the frame, and first information corresponding to a number of the rectangular regions in the frame, wherein all of the identifier, the position, and the first information to be obtained are signalled in the single parameter set in the bitstream, a flag related to loop filtering across boundaries of the rectangular region is signalled in the bitstream, and second information, different from the first information corresponding to the number of the rectangular regions in the frame, of the number of bits used to represent the identifier of each one of the rectangular regions in the frame is further signalled in the bitstream in a state where a different identifier to be obtained is assigned to a different one of the rectangular regions in the frame, the number of bits being a variable number; and
decoding the frame portions from the bitstream.
