When the selected file is played back, the controller 70 checks whether a key input signal is input from the key input unit 50 in real time.

That is, when the user inputs a desired time, ie, a play request time, as a number by using the key input unit 50 (S230: Y), the controller 70 controls the video file playback unit 22 or the music file. The playback unit 24 is controlled to play the video file or the music file at a point corresponding to the playback request time (S240). At this time, the reproduction request time may be input in units of hours, minutes, and seconds.

 FIG. 3A is a diagram illustrating a configuration of the key input unit of FIG. 1, and FIG. 3B is a diagram illustrating an example of a file playback screen.

Referring to FIG. 3A, the user uses the numeric keys 52 of the key input unit 50 to input the numbers, uses the * button 54 to distinguish between minutes and seconds, and completes the play request time input. Enter button 56.

For example, if the file is to be played back from 1 hour 10 minutes 30 seconds (70 minutes 30 seconds) while the file is being played for 2 hours (120 minutes), the user may enter 70 * 30 #. In the present embodiment, the button used to distinguish minutes and seconds has been described as an example of the * button 54 and the button used after the completion of the input of the play request time, as an example, but various buttons may be used. have.
