Claim 5:
6. A device for decoding a coded video sequence, the device comprising:
at least one memory configured to store program code; and
at least one processor configured to read the program code and operate as instructed by the program code, the program code including:
decoding code configured to cause the at least one processor to decode a tile which comprises a first tile boundary defined by a first tile layout and a second tile boundary defined by a second tile layout,
wherein the coded video sequence indicates that at least one first prediction mechanism is available across the first tile boundary, and that the at least one first prediction mechanism is not available across the second tile boundary,
wherein the first tile layout comprises a parallelization-driven tile layout and is described in a first syntax structure of the coded video sequence,
wherein the second tile layout comprises an application-driven tile layout and is described in a second syntax structure of the coded video sequence,
wherein the first syntax structure is a higher level syntax structure than the second syntax structure,
wherein the first syntax structure comprises a sequence parameter set, and
wherein the second syntax structure comprises a picture parameter set.
