Extracting Multiple Identifiers from Audio and Video Content
First Claim
1. A method comprising:
- extracting first identifying information from data representing audio elements of an audio signal, said act of extracting first identifying information from data representing audio elements of the audio signal utilizes a programmed electronic processor;
extracting second identifying information from data representing picture elements of a video signal that is associated with the audio signal, said act of extracting second identifying information from data representing picture elements of the video signal utilizes a programmed electronic processor; and
utilizing the first identifying information or the second identifying information in a synchronization process, said synchronization process controls content synchronization during rendering of the audio signal or the video signal.

Abstract
The presently claimed invention relates generally to content identification, such as extracting identifying information from content itself. One claim recites a method including: extracting first identifying information from data representing audio elements of an audio signal, said act of extracting first identifying information from data representing audio elements of the audio signal utilizes a programmed electronic processor; extracting second identifying information from data representing picture elements of a video signal that is associated with the audio signal, said act of extracting second identifying information from data representing picture elements of the video signal utilizes a programmed electronic processor; and utilizing the first identifying information or the second identifying information in a synchronization process, said synchronization process controls content synchronization during rendering of the audio signal or the video signal. Of course, other combinations and claims are provided as well.
