1. A non-transitory processor-readable medium having instructions stored thereon that, when executed by a processor, cause the processor to:
receive a coded bitstream comprising an encoding of a sequence of video pictures and metadata parameters, wherein the metadata parameters include shutter interval parameters comprising:
a shutter interval temporal sub-layer index of a current picture in the coded bitstream, wherein
if the shutter interval temporal sub-layer index equals to zero, then the metadata parameters include a shutter interval information present flag, wherein if the shutter interval information present flag is equal to one, then the metadata parameters include:
a shutter interval time-scale parameter indicating the number of time units passing in one second;
a fixed-shutter-interval-duration flag indicating whether shutter interval duration information is fixed for all pictures in the sequence of video pictures; and
if the fixed-shutter-interval-duration flag indicates that the shutter interval duration information is fixed, then the metadata parameters include
a shutter interval clock-ticks parameter indicating a number of time units of a clock operating at the frequency of the shutter interval time-scale parameter,
else, the shutter interval parameters include an array of one or more sub-layer shutter interval clock-ticks parameters indicating a number of time units of a clock at the frequency of the shutter interval time-scale parameter for one or more sub-layers in the encoding of the sequence of video pictures, wherein, for a first sub-layer in the encoding of the sequence of video pictures, a corresponding sub-layer shutter interval clock-ticks parameter divided by the shutter interval time-scale parameter indicates the exposure duration value for all the video pictures in the first sub-layer of the encoding of the sequence of video pictures; and
decode the sequence of video pictures based on the shutter interval parameters.
