Abstract

A method for estimating the type of the GoP structure of a plurality of video frames in a video stream by estimating their frame types includes: capturing frame sizes in bytes of every video frame subsequent to an initial I-frame to obtain an array of frame sizes by exploiting features of a transport layer carrying the video stream; converting, after a number of frames, the array of frame sizes into an array of zeros and ones; matching the binarized array of frame sizes to a number of predefined short basic binary patterns, said predefined binary patterns depicting all GoP structures to be considered; converting the result of said matching to form a single score value; and determining the particular pattern of the number of predefined patterns of binaries having the best score value, according to a predefined metric.
