As a method of recognizing one unit of the recorded information, for example, in reproducing a recorded music, a silent portion between the songs is detected by monitoring a signal level, and the detected silent portion is detected. The voiced part sandwiched between the music pieces may be recognized as one piece of music.

Similarly, in the speech, by monitoring the level of the signal, a silence portion where no speech is made is detected, and a speech portion sandwiched by the detected silence portions is regarded as a one-segment speech. Can be recognized.

Further, in cutting an image, the luminance level of the screen is monitored, and when the luminance level changes substantially continuously, it is recognized that the image of the same cut is continued, and the substantially discontinuous state is obtained. By recognizing that the transition has been made to another cut when the number has changed to one, one cut can be recognized.

Of course, what has been described here is an example of a method for recognizing a recording information unit, and other means can be widely applied. Further, it is needless to say that one unit of the recording information is not limited to the above-mentioned one piece of music, one section of remark, or one piece of video.
