1. A method for processing an encoded video stream using a processor, the method comprising: receiving a coded bitstream comprising an encoded picture section including an encoding of a sequence of video pictures and a supplemental enhancement information (SEI) message including shutter interval parameters, wherein the shutter interval parameters comprise:
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 SEI message includes a shutter interval information present flag, wherein if the shutter interval information present flag is equal to one, then the SEI message includes:
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 encoded picture section; and
if the fixed-shutter-interval-duration flag indicates that the shutter interval duration information is fixed, then the SEI message includes
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, wherein the shutter interval clock-ticks parameter divided by the shutter interval time-scale parameter indicates an exposure duration value for all the video pictures in the encoded picture section,
else, the shutter interval parameters includes 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 encoded picture section, wherein, for a first sub-layer in the encoded picture section, 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 encoded picture section; and
decoding the sequence of video pictures based on the shutter interval parameters.
