FIELD: information technologies.
SUBSTANCE: device (3400) for processing of coded data flow (3401), comprising a decoding module (3402) to generate decoded data flow (3403) from coded data flow (3401), detection module (3404) for detection of information on position of at least one intra-coded frame in coded data flow (3403) and substitution module (3405) for substitution on the basis of detected information on position of coded data flow (3401) parts with according parts of decoded data flow (3403).
EFFECT: increased efficiency, speed of data flow processing by means of selective substitution of only that data in data flow, which is required for further use of data flow.
