Classification: CPC H | IPC H

Claim 14:
15. A decoding device, comprising:
a receiver configured to receive a coded video bitstream;
a memory coupled to the receiver, the memory storing instructions; and
a processor coupled to the memory, the processor configured to execute the instructions to cause the decoding device to:
receive the coded video bitstream, wherein the coded video bitstream contains a picture, the picture including one or more slices having one or more tiles, each tile containing a plurality of coding tree blocks (CTBs);
encounter an end of tile bit with a first value and byte alignment bits in the coded video bitstream, the end of tile bit with the first value and the byte alignment bits indicating that a current CTB from the plurality of CTBs is a last CTB in a tile;
encounter an end of CTB row bit with the first value and the byte alignment bits in the coded video bitstream when the end of tile bit with the first value is absent from the coded video bitstream, the end of CTB row bit with the first value and the byte alignment bits indicating that waveform parallel processing (WPP) is enabled and that the current CTB from the plurality of CTBs is the last CTB in a CTB row but not the last CTB in the tile; and
reconstruct the plurality of CTBs in the tile based on the end of tile bit with the first value, the end of CTB row bit with the first value, and the byte alignment bits.
