摘要:
The present embodiments introduce a new type of random access point in video bitstreams that can be used for random access operations but can be represented in encoded form at a lower bit cost as compared to IRAP pictures. The random access point is a dependent random access point (DRAP) picture that is encoded and decoded as a temporal predictive picture using an IRAP picture and/or a previous, according to a decoding order, DRAP picture as sole reference picture(s) for the DRAP picture. The DRAP picture constitutes a random access point in a video bitstream.
