摘要：
An information processing apparatus capable of accurately detecting one or more commercials included in a television broadcast. A commercial candidate segment detector detects a commercial candidate segment on the basis of silent segments and scene change points. A commercial block detector detects a commercial block, which is composed of a plurality of commercial segments and is interposed between one program portion and another, in conformity with numbers of frames of the individual commercial candidate segments detected by the commercial candidate segment detector, and then outputs to a switch a control signal based on the result of such commercial block detection.
