1. A method of coding implemented by a decoding/encoding device for coding video data, comprising:
coding, in a supplemental enhancement information (SEI) message, a set of sequence parameters,
wherein the set of sequence parameters is associated with temporal IDs (TIDs) of sub-layers of a bitstream or coded layer video sequence (C(L)VS);
processing the bitstream or C(L)VS by using the set of sequence parameters included in the SEI message;
wherein the set of sequence parameters is used for deriving or representing a picture rate of a sequence;
wherein the set of sequence parameters includes a number of units in clock ticks of a highest TID and the highest TID, and wherein the processing of the bitstream or C(L)VS by using the set of sequence parameters comprises:
deriving a number of units in clock ticks for a sub-layer associated with a particular TID by division of the number of units in clock ticks of the highest TID by the highest TID minus current TID to the power of 2; and processing the bitstream or C(L)VS based on the number of units in clock ticks for the sub-layer.
