  By doing so, it is possible to obtain an effect that thumbnails can be displayed on the EPG displayed in a normal size, and the program title and program description behind can be read.

  As a specific example of a method for determining whether or not the program is commercial, the control unit 261 executes the program read from the ROM 261a, or the control unit 261 determines whether the program is commercial or not.・ Automatically distinguish from voice information to recognize and use commercials. For example:

  For example, if a program is recorded in a loop and the same characters as the program title are detected in the image of the program, or if the audio of the program title is detected, the detected 30 seconds before and after are detected as a program commercial. Thus, it is extracted from the loop recording and stored in a recording medium different from the loop recording.

  In addition, for example, it is detected that the same character as the program title is detected in the program image, and the silent part existing before and after the detection is set as the program commercial, which is extracted from the loop recording and separated from the loop recording. For example, it may be stored in a recording medium.

  As described above, according to the present invention, it is possible to create an electronic program guide in which thumbnails, program titles, and program descriptions are arranged at the same time in each grid-displayed program area.
