Abstract: Embodiments provide for outputting video and allowing a user to switch between different audio steams in a synchronous manner without impacting the timeline of the audio presentation. The audio and video streams may be directed to a single sporting event. For example, a user can view video associated with a national television broadcast of a baseball game, and switch between the audio from the national broadcast and the audio from the radio broadcast. Similarly, the user can view video associated with a local television broadcast, and switch between the audio from the national, regional, and/or radio broadcast. As any sport fan would appreciate, such flexibility enables users to watch the video with, e.g., the best quality and camera angle, while at the same time listening to the audio or broadcaster they find the most appealing.

Abstract: This invention relates to a device and a method of generating a first and a second fingerprint (102,104) usable for synchronisation of at least two signals (101,103) and corresponding method and device for synchronising two or more signals. A fingerprint pair is generated on the basis of a segment of a first signal e.g. an audio signal and of a segment of a second signal e.g. a video signal at each synchronisation time point. The generated fingerprint pair(s) are stored in a database (203) and communicated or distributed to a synchronisation device (303). During synchronisation, fingerprint(s) of the audio signal and fingerprint(s) of the video signal to be synchronised are generated and matched against fingerprints in the database. When a match is found, the fingerprints also determine the synchronisation time point, which is used to synchronise the two signals. In this way, a simple, reliable and efficient way of synchronising at least two signals is obtained.
