Claim:
1. Method for matching a corresponding video frame in a first and a second multimedia streams containing multimedia data, wherein the multimedia data include at least a video stream and an audio stream, wherein the first multimedia stream is provided with meta-data, and wherein the method comprises: receiving the second multimedia stream; receiving the meta-data and audio-fingerprints of the first multimedia stream; detecting a video shot boundary in the second multimedia stream and a first video frame following the video shot boundary in the second multimedia stream; determining the audio-fingerprint of a sequence of video frames including the video shot boundary and the first video frame after the video shot boundary has been detected in the second multimedia stream; matching the determined audio-fingerprint with an audio-fingerprint of the first multimedia stream, wherein the audio-finger print matching is used to determine coarse synchronization of a sequence of corresponding video frames in the first and the second multimedia streams, the coarse synchronization does not satisfy frame accurate synchronization of the corresponding video frame; determining a video sequence in the first multimedia stream corresponding to the matching audio-fingerprint to provide the coarse synchronization; detecting a video shot boundary in the video sequence in the first multimedia stream; and identifying a second video frame following the video shot boundary in the video sequence, wherein the second video frame matches with the first video frame to provide the frame accurate synchronization of the corresponding video frame.
