Abstract:
1. A video data processing method, comprising: extracting visual parameter values and audio parameter values from the video data; detecting in the video data visual boundary events associated with respective ones of the extracted visual parameter values that satisfy at least one visual boundary condition, audio boundary events associated with respective ones of the extracted audio parameter values that satisfy at least one audio boundary condition, and commercial content transition events associated with respective ones of the extracted visual and audio parameter values that satisfy at least one condition that distinguishes commercial type content from program type content; determining candidate commercial blocks of consecutive commercial content 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 being defined between respective candidate starting and ending boundary points; and adjusting ones of the starting and ending boundary points of the candidate commercial blocks based on occurrence of one or more of the detected commercial content transition events within temporal windows respectively encompassing the starting and ending points.
