FIELD: physics, computer engineering.
SUBSTANCE: invention relates to image data processing means. The method involves calculating overall differential brightness of each difference frame and the brightness threshold of three previous difference frames, comparing brightness characteristics of the difference frame with the threshold of the overall differential brightness calculated during replacement of video stream frames, identifying the first boundary of an insert frame and identifying an insert frame of said stream.
EFFECT: fewer erroneous detections of insert frames in multimedia data stream.
