Establishment and use of interpolation based time mapping using low rate fingerprinting to aid in smooth content correction of frame accuracy

摘要

Computer system(I) identify the plurality of coincidence points between the query fingerprint representing the media stream received by the client and the (II) fingerprintEach identified matching point isClient client time stamped query fingerprints according to the client's clockThe determined real time in accordance with the timeline in the known media stream defines the respective matching between the timed reference fingerprints.Furthermore, the computer system performs linear regression based on the time stamp of the coincidence point and establishes a mapping between the real time and the client time.Next, the computer system uses this mapping to determine the client time point for the client to perform content modification or other operations on the media stream received by the client.The computer system also causes the client to perform content modification or other operations at the determined client time.Diagram
