FIELD: information technologies.
SUBSTANCE: CSF is developed with one or more units of network abstraction level (NAL) as a frame of a random access point (RAP), and adjacent frames are sent, which include CSF and a frame, which is not a RAP frame, besides, each of them has an identical identification number.
EFFECT: provision of video coding and video decoding of channels switching frames, making it possible to provide for a grip and resynchronisation of a video flow with preservation of compression efficiency.
