摘要:A novel and universal audience rating system based on TV audio features is introduced. In this system, the audio signal is sampled from the audio outlet of TV set and high compressed into a specific spectrum features packages. The packaged audio features are high robustness for different types of television sets and sound volumes, and have no disturbance of surroundings. In the channel audio retrieval method, feature vector correlation analysis and pattern matching are adopted successively. The simulation test results show that the TV channel recognition rate is above 93%, and other sounds from non-TV channels can be detected reliably.
