ABSTRACT:
Systems and methods of detecting blocks of commercial content in video data are described. In one aspect, visual parameter values and audio parameter values are extracted from the video data. Visual boundary events, audio boundary events, and commercial content transition events are detected in the video data. Candidate commercial blocks of consecutive commercial content are detected in the video data from a combination of the detected visual boundary events and the detected audio boundary events. Each of the candidate commercial blocks is defined between respective candidate starting and ending boundary points. Ones of the starting and ending boundary points of the candidate commercial blocks are adjusted based on occurrence of one or more of the detected commercial content transition events within temporal windows respectively encompassing the starting and ending points.
