Abstract:
There are provided methods and apparatus for film grain SEI message insertion for bit-accurate simulation in a video system. A method for simulating film grain in an ordered sequence includes the steps of providing film grain supplemental information corresponding to a plurality of intra coded pictures, and providing additional film grain supplemental information corresponding to inter coded pictures between consecutive intra coded pictures, in decode order. The inter coded pictures are selected based upon display order.
