DIGEST GENERATION DEVICE, DIGEST GENERATION METHOD, RECORDING MEDIUM STORING DIGEST GENERATION PROGRAM THEREON AND INTEGRATED CIRCUIT USED FOR DIGEST GENERATION DEVICE

摘要

A feature amount calculating section (12) calculates a feature amount based on received AV signals. A silent segment detecting section (13) detects a segment having an audio power level smaller than or equal to a predetermined value as a silent segment. A candidate segment detecting section (14) detects a segment having the audio power level greater than or equal to the predetermined value as a digest scene candidate segment. A CM segment determining section (15) determines a CM segment based on a time difference between the silent segment and another silent segment. A digest list creating section (16) deletes a determined segment corresponding to the CM segment from digest candidate segments, thereby generating digest scene information based on a program segment excluding the CM segment.
