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, wherein the act of extracting first identifying information from data representing audio elements of the audio signal utilizes a processor;
extracting second identifying information from data representing picture elements of a video signal that is associated with the audio signal, wherein the act of extracting second identifying information from data representing picture elements of the video signal utilizes a processor; and
utilizing the first identifying information or the second identifying information in a synchronization process, wherein the synchronization process controls content synchronization during rendering of the audio signal via a speaker or during rendering of the video signal via a display.

Abstract
The disclosure concerns content identification, such as extracting identifying information from content itself. One combination described in the disclosure is a method including: extracting first identifying information from data representing audio elements of an audio signal, the 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, the 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, the synchronization process controls content synchronization during rendering of the audio signal or the video signal. Of course, other combinations are provided as well.
