FIELD: information technology.
SUBSTANCE: invention relates to video encoding. Techniques for decoding video data include receiving a bitstream that includes one or more pictures CVS, decoding a first picture according to a decoding order, wherein first picture is a RAP picture that is not an IDR picture, and decoding at least one other picture following first picture according to decoding order based on decoded first picture. Techniques for encoding video data include generating a bitstream that includes one or more pictures of a CVS, wherein a first picture according to decoding order is a RAP picture that is not an IDR picture, and avoiding including at least one other picture, other than first picture, that corresponds to a leading picture associated with first picture, in bitstream.
EFFECT: technical result consists in improvement of functional compatibility of systems and devices for encoding and decoding video.
