Patent ID: 8422853

Claim:
An information signal processing method using a microprocessor, wherein when a first information signal including at least image and voice data is used to generate a second information signal including at least image and voice data, in case the first information signal includes a first playback information for setting a playback section of the first information signal or setting a predetermined playback point in the first information signal, data is extracted from the first playback information by separating the data into image and voice data, sending the voice data to a first stream data analyzer, and sending the image data to a second stream data analyzer, and used to generate second playback information for setting a playback section of the second information signal or setting a predetermined playback point in the second information signal by analyzing the voice data in the first stream data analyzer and analyzing the image data in the second stream data analyzer, wherein: analyzing the voice data further includes determining if the voice data represents silence, music, a speaker's voice, applause, or cheer; analyzing the image data further includes: detecting a scene change based on dividing a screen into predetermined sub area, calculating mean values of brightness data and color difference data; and utilizing the mean values of brightness data and color difference data, with voice attribute data, to determine that the voice data and image data correspond to one of a preselected scene.
