    • A particular program detection device is provided which can detect 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 (12) detects a noise level of a program signal outputted from a signal input section (11). Based on the noise level detected by the noise level detecting section (12), a detection sensitivity determining section (13) determines a detection sensitivity which is used when a silent portion of the program signal is determined by a silent portion detecting section (14). In accordance with the detection sensitivity determined by the detection sensitivity determining section (13), the silent portion detecting section (14) detects a portion having a low audio level of the program signal as a silent portion. A particular program determining section (15) calculates a time difference between each silent portion detected by the silent portion detecting section (14) and a silent portion following this, and based on the calculated time difference, determines whether or not the silent portion is a particular program.
    • 提供了一种特定的程序检测装置,即使在通过自适应地修改场景变化点的检测灵敏度的情况下,即使在被噪声污染的程序信号中也能够检测特定的程序段。 噪声电平检测部分(12)检测从信号输入部分(11)输出的节目信号的噪声电平。 根据噪声电平检测部分(12)检测到的噪声电平,检测灵敏度确定部分(13)确定当由无声部分检测部分(14)确定节目信号的静音部分时使用的检测灵敏度, 。 根据由检测灵敏度确定部分(13)确定的检测灵敏度,无声部分检测部分(14)将节目信号的低音频电平的部分检测为无声部分。 特定节目确定部分(15)计算由无声部分检测部分(14)检测到的每个无声部分与之后的无声部分之间的时间差,并且基于所计算的时间差,确定无声部分是否为 特定程序。
