Abstract
A method and an apparatus for matching corresponding frames in two multimedia streams are suggested. The first multimedia stream is an original multimedia stream for which meta-data are available. The second multimedia stream is broadcasted or multi-casted multimedia stream and has undergone processing steps such that the meta-data of the original video stream are no more available or no longer reliable. The matching of corresponding frames in the two multimedia streams is based on the comparison of audio fingerprints and the detection of shot boundaries. Matching corresponding frames with frame accuracy enables inserting targeted content like advertisements into a sequence of video frames especially in a broadcast or multicast environment where meta-data and time markers cannot be relied upon.
