16. A non-transitory digital storage medium having a computer program stored thereon to perform, when the computer program is run by a computer:
decoding a supplemental enhancement information (SEI) message from a data stream, the SEI message indicating that coding of all random access skipped leading (RASL) pictures within a sequence of pictures is constrained in a manner excluding a predetermined set of one or more coding tools, the predetermined set comprising
a cross-component linear-model based prediction tool, and
a decoder-side motion vector refinement tool,
the sequence of pictures comprising at least one random access skipped leading (RASL) picture and a clean random access (CRA) picture associated with the at least one RASL picture.
