特定番組検出装置及び方法並びにプログラム
Document Type and Number:
Japanese Patent JP4675884
Kind Code:
B2
Abstract:
A particular program detection device detecting a particular program segment even in a program signal contaminated with noise by adaptively modifying a detection sensitivity for a scene change point. A noise level detecting section detects a noise level of a program signal outputted from a signal input section. Based on the detected noise level, a detection sensitivity determining section determines a detection sensitivity which is used when a silent portion of the program signal is determined by a silent portion detecting section. In accordance with the determined detection sensitivity, the silent portion detecting section detects a portion having a low audio level of the program signal as a silent portion. A particular program determining section calculates a time difference between each silent portion and a silent portion following this, and based on the calculated time difference, determines whether or not the silent portion is a particular program.
