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.

Abstract: There is provided an AV content processing device operable to reduce unpleasantness caused to a user when a detection error occurs in detecting a CM section. A CM detection unit (101) detects a CM section based on a power level of a sound signal in a stored AV content or the like, and acquires information indicating boundaries between the CM section and program sections. The user inputs, via a purpose reception unit (102), a view purpose to view the AV content. Boundary A boundary correction unit (103) shifts, in accordance with the view purpose inputted by the user, positions of the boundaries (a start point and an end point) between the CM section detected by the CM detection unit (101) and the program sections such that the detected CM section becomes long or short.

Abstract: 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.

Abstract: It is an object of this invention to provide a graphic display apparatus that reduces the amount of CG data transferred from a server through a network and that allows three-dimensional characters displayed at a terminal to move smoothly. It is another object of this invention to provide an AV synchronous reproduction apparatus that can synchronize an image with a score the tempo of which is changed during reproduction. According to this invention, when a server instructs a terminal to graphically display three-dimensional characters, the terminal provides a plurality of motion patterns. The server then transmits scenario data to the terminal, and the terminal operates based on the scenario data to switch scenes for graphical displays. The terminal switches the scenes for graphical displays with a timing for a home position which is common or substantially common to a motion pattern being executed and a motion pattern to be executed next.
