<p>A method of encoding a video sequence is provided. The method (300) comprises including (301) Network Abstraction Layer (NAL) unit type information with each picture of the video sequence, and identifying (302) a current picture which is a leading picture of exactly one Clean Random Access (CRA) picture. The current picture is identified using the NAL unit type information, e.g., using a specific NAL unit type which is reserved for leading pictures of exactly one CRA picture. Further, a method of decoding a coded video sequence, a method of extracting a sub-bitstream from a coded video sequence, a method of processing a coded video sequence, corresponding computer programs and computer program products, a video encoder, a video decoder, and network elements are provided.</p> |
