STREAM SYNCHRONIZATION USING AN AUTOMATED DIGITAL CLAPPERBOARD

Abstract:

An approach is provided in which the approach receives a media stream comprising an audio stream and a video stream. The audio stream includes a set of audio tones inserted at a set of predetermined frame intervals, and the video stream includes a set of predetermined colors inserted into a set of predetermined pixel locations at the predetermined frame intervals. The approach determines that an audio frame in the audio stream at which the set of audio tones are inserted is misaligned in time with a video frame in the video stream at which the set of predetermined colors are included in the set of predetermined pixel locations. The approach synchronizes the audio stream with the video stream in response to the determination and aligns in time the audio frame with the video frame at one of the predetermined frame intervals.
