FIELD: information technologies.
SUBSTANCE: video data of improvement level is included into component of network abstraction level (NAL); one or several syntactic elements are included into NAL to indicate, whether NAL component includes video data of improvement level, and one or several syntactic elements to indicate at least one of the following: whether video data of improvement level include video data with intraframe coding in NAL component; whether NAL component includes parametre of sequence, set of image parametres, layer of reference image or section of data of reference image layer; and number of nonzero coefficients with value exceeding one, in units of intraframe coding in video data of improvement level.
EFFECT: realisation of expansion of versions of International Telecommunication Union standard for efficient scalable video coding.
