On the other hand, the apparatus of FIG. 1 is provided with means for displaying the setting process of the search time on a screen so that a user can easily set the above-mentioned screen search time. In FIG. 1, the system controller 13 determines how many times the user has selected the timer search key and outputs an OSD display to the OSD unit 14 for displaying the setting of the search time. The system controller 13 also controls the display unit 15 to display on the screen an image (hereinafter referred to as a display image) indicating that the screen search time is set. The OSD unit 14 converts an OSD signal applied from the system control unit 13 into an OSD character to be displayed on the screen and outputs the OSD signal to the signal synthesis unit 16. In this case, the display unit 15 outputs the above-described display image to the signal synthesis unit 16. The signal synthesizing unit 16 synthesizes the input OSD character and the display image and outputs the synthesized OSD to the monitor.

FIG. 2 is a diagram illustrating an example of a display image and an OSD display displayed on a screen when an operation of the apparatus of FIG. 1 is executed. As shown in the figure, when the user selects the timer search key of the user input unit 11 or the remote control device 12, the above-described display image is displayed on the screen, and the search time set up to now displays OSD characters in a certain section on the screen. Is displayed. If the screen to be played for 10 seconds is configured to be searched every time the timer search key is pressed, the OSD character on the screen is displayed as [TIMER SEARCH: 10 SEC, 20 SEC,... ] And the like. The display screen as shown in FIG. 2 is displayed until the user finishes inputting the timer search key and setting of the search time is completed.

Again, in FIG. 1, the system controller 13 sets the search execution time by counting the number of times of the above-described timer search key, and controls the deck 17 to execute the search of the tape by the set time. The process of controlling the screen search according to the input of the timer search key in the system controller 13 will be described with reference to FIG. 3.

The operation of the screen skip device using the timer search of the present invention configured as described above will be described in more detail.

In the case of performing screen search of an image program recorded on a recording medium such as a video tape, the user can use the timer search key provided in the user input unit 11 or the remote control device 12 of FIG. Set the time to run. At this time, the device of the present invention is set to execute the search of the screen to be reproduced for a predetermined unit time (for example, 10 seconds) every time the timer search key is pressed as described above. In FIG. 3, the system controller 13 first checks whether the above-described timer search key has been input (step 101). When the timer search key is input, the system controller 13 counts the number of times the timer search key is input (step 102). At this time, the system controller 13 controls the display unit 15 to display a display image indicating that the screen search time is set, and generates an OSD signal for displaying the setting of the search time. Will output The display unit 15 outputs the above-described display image to the signal synthesizing unit 16 under the control of the system control unit 13, and the OSD unit 14 converts the above-described OSD signal into OSD characters for displaying on the screen. The signal is output to the signal synthesizing unit 16.
