PICTURE ORDER COUNT ALIGNMENT IN SCALABLE VIDEO

摘要

A POC recalculation value is retrieved by a decoder from an encoded representation of a RAP picture in a base layer of a video stream comprising pictures in multiple layers. POC values of reference pictures in a DPB of the decoder are recalculated using the POC recalculation value. By signaling the POC recalculation value in the RAP picture, which enables the decoder to correctly handle video streams with non-aligned RAP pictures.

1. A method performed by a decoder, said method comprising:
retrieving a picture order count, POC, recalculation value from an encoded representation of a random access point picture in a base layer of a video stream comprising pictures in multiple layers; and recalculating POC values of reference pictures in a decoded picture buffer of said decoder using said POC recalculation value.
