PROBLEM TO BE SOLVED: To detect highlight scene without using reference information and without being greatly influenced by encoding distortion. SOLUTION: A spectrum is detected by a spectrum calculation module 22 by dividing an audio data included in a multi-media content for each fixed section. Then, a cheering voice feature amount composed of a frequency value (peak frequency) and its power value, which become a maximum value and a local maximal value in a specified bandwidth in which a cheering voice feature appears in the detected spectrum, is detected by a cheering voice feature amount extracting module 23. Then, in a cheering voice section judgement module 24 and in preset time length, the section in which the state of the detected cheering voice feature amount being higher than a threshold exists for a time length more than a judgement threshold rate is judged as a cheering section, and a display data for expressing the judgement result of the cheering voice section is created and output by an output control module 25.
