1. A system comprising:
a receiver configured to receive a bitstream; and
a processor coupled to the receiver, wherein the processor is configured to:
decode the bitstream to produce a first picture,
determine a first value using a ratio of a luma picture size of the first picture in samples and a maximum luma picture size;
determine a second value using a maximum number of tile columns and using a maximum number of tile rows; and
constrain a removal time to satisfy a constraint that a number of tiles in the first picture is less than or equal to a minimum value of the first value and the second value.
