A novel commercial break detection and automatic annotation of TV programs for content based retrieval

In this paper, we present a novel approach for automatic annotation and content based video retrieval by making use of the features extracted during the process of detecting commercial boundaries in a recorded Television (TV) program. In our approach, commercial boundaries are primarily detected using audio and the detected boundaries are enhanced and validated using logo (program name) in the video domain. Detected logo (program name) at the commercial boundaries is used for automatic annotation of recorded video which helps in fast content based video retrieval. The performance and validity of our approach is demonstrated using the videos recorded from different Indian Television broadcasts.
