Abstract
Methods and apparatus for identifying audio/video content using temporal characteristics of a signal are disclosed. The disclosed apparatus and methods detect a plurality of signal features of a media signal derived from audio/video content and calculate time intervals between a plurality of those signal features to generate signatures. The signatures are then used to identify the audio/video content.
Claims18
A method of identifying audio/video content, the method comprising:
- receiving a media content signal:
- determining a first time difference between a first peak value and a second peak value associated with the media content signal;
- adding the first time difference and a second time difference to determine an index value of a signature;
- querying a database based on the index value to form query results;
- and
- identifying the media content signal based on a statistical analysis of the query results.
An apparatus for identifying audio/video content, comprising:
- a memory;
- and
- a processor coupled to the memory and programmed to:
- receive a media content signal;
- determine a first time difference between a first peak value and a second peak value associated with the media content signal;
- add the first time difference and a second time difference to determine an index value of a signature;
- query a database based on the index value;
- and
- identify the media content signal based on a statistical analysis of query results.
A machine readable medium having instructions stored thereon that, when executed, cause a machine to:
- receive a media content signal;
- determine a first time difference between a first peak value and a second peak value associated with the media content signal;
- add the first time difference and a second time difference to determine an index value of a signature;
- query a database based on the index value;
- and
- identify the media content signal based on a statistical analysis of query results.
