FIELD: video technology.
SUBSTANCE: invention relates to means for video coding. Video data are received. The high-level syntax of video data is analyzed. Then, determining whether the value of the syntactic element of the high-level syntax indicates the value of the image sequence number (ISN) for the video data access unit (AU). Assigning at least one of the many images, slices and tiles of video data to the access unit based on the value of the syntactic element. Determining whether the high-level syntax includes a flag indicating whether at least one of the images is divided into multiple subdomains. Setting the size of the input image of at least one of the images equal to the size of the coded image signaled in the sequence parameter set (SPS) of video data, in response to the determination that the high-level syntax includes a flag indicating that at least one of the images is not divided into multiple subdomains.
EFFECT: increase in coding efficiency.
