Such a video cassette recorder has a reserved recording function, which is a reservation information input by a user (for example, a broadcast date, start time, end time, broadcast channel of a desired program, and recording speed). It is a function to reserve and record a broadcast program in advance by setting, and to automatically record a broadcast program desired by the user in the absence of the user, so that the user can play and watch it next time.

On the other hand, the video cassette recorder has a program for changing the country, that is, when a selection key signal corresponding to the country change is applied from the user, the microcomputer converts and displays the character information corresponding to the changed country. For example, when the country is changed from Germany to the United Kingdom, the microcomputer converts the text information suitable for English and displays the converted English text information on the screen.

However, this country changing program of the video cassette recorder converts and displays the character information corresponding to the changed country, but the time information is preset without changing, so that the user can perform the scheduled recording as described above without modifying the time information. There is a problem that can be recorded if you do not want to run, there was a hassle to change the time information yourself.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem, and an object of the present invention is to provide a time setting method of a video cassette recorder which resets the time information corresponding to the changed country when a country change is selected by the user. have.

Features of the present invention for achieving the above object, the menu screen display step of displaying a menu screen when a signal for the menu key is input; A country change selection signal input determination step of determining whether a signal for selecting a country change is input from the menu screen displayed in the menu screen display step; A time information clearing step of clearing predetermined time information when a signal for selecting a country change is input; And a time information resetting step of resetting new time information according to the time difference between the country before the change and the country to be changed.

The above objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the appended figures by those skilled in the art.

Hereinafter, with reference to the accompanying drawings will be described in detail the operation of the preferred embodiment of the present invention.

1 is a block diagram showing a configuration of a time setting device of a video cassette recorder according to the present invention, wherein a key input unit 10, a microcomputer 20, a playback system 30, a recording system 40, an OSD (on screen display) It consists of a part 50.

In this configuration, the key input unit 10 is composed of key metrics as input means for operating the video cassette recorder, and includes a plurality of keys such as a menu key, a playback key, a recording key, and a numeric key for inputting reserved recording information. It is provided with a key signal corresponding to the user's key operation to the microcomputer 20 to be described later, and typically detects the key signal carried on the infrared carrier wave from the remote control by using a remote control that can be input from a remote location.

At this time, the microcomputer 20 outputs a control signal corresponding to the key signal output from the key input unit 10 to control the overall operation of the video cassette recorder.

That is, when the signal for the menu key is input from the key input unit 10, the microcomputer 20 receives the blue back signal and the character control signal for the OSD menu, that is, the address information of the OSD text and the data of the OSD text. To the OSD unit 50.

Accordingly, the OSD unit 50 displays the blue back screen according to the blue back signal output from the microcomputer 20, and displays the OSD text at the position of the corresponding address based on the text control signal for the OSD menu. Display.

In addition, when the signal for selecting a country change is input from the key input unit 10, the microcomputer 20 includes a time information clear signal for clearing the time information set as an internal timer, a country before the preset change, and a selected country, that is, A time information reset signal for setting new time information according to the time difference of the country to be changed is output to an internal timer.

Therefore, the timer clears the preset time information according to the time information clear signal of the microcomputer 20, and also sets the time according to the time information reset signal, that is, resets the time corresponding to the country to be changed.

On the other hand, when the signals for the recording key and the reserved recording key is input from the key input unit 10, the microcomputer 20 performs recording and scheduled recording according to the time reset by the internal timer as described above. Output a control signal.

Therefore, the recording system 40 performs recording according to control signals and time information for performing recording and scheduled recording output from the microcomputer 20.
