Description

How to enter the date of the video cassette recorder

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video cassette recorder (hereinafter abbreviated as BC), and more particularly, to a method of inputting a date of a V-Cal in which a plurality of date display information is stored.

V-Cal is a device for recording video and audio signals on a video tape which is a magnetic body using a magnetic head mounted on a rotating head drum, or reading and outputting video and audio signals recorded on the video tape.

The VRC includes a ten key, which is a numeric key input means. By this ten key, VRC can set a current date or a scheduled recording date. That is, a ten key consists of buttons indexed with ten Arabic numerals (0 to 9), respectively, and when a corresponding button among these ten buttons is input, a predetermined date is displayed on a television screen or a digitron, and the current date or It is set as the scheduled recording date.

As described above, it can be seen that the conventional date input method includes a process of completing a date setting by inputting a desired date while checking a ten key and a display unit. In other words, the problem that the date input process is not only cumbersome, but is often incorrectly input by the user.

Accordingly, an object of the present invention is to provide a method for entering a date of V-Cal to facilitate a user's date input by displaying a plurality of date information.

That is, the present invention provides a method of inputting a date of a V-Cal, comprising: determining whether a date is set; If the date is set, displaying preset current date information and a plurality of dates close to the current date; Determining whether one of a plurality of dates is selected; And setting a selected date as a current date.

The above objects and various advantages of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic block diagram of a VRC for performing a method according to the present invention, in which a left / right shift key 12 and an enter key 14 and a micom 20 in a key input unit 10 are shown. ), A memory unit 30 and a display unit 40.

As shown in the drawing, the key input unit 10 includes a plurality of function keys for controlling the operation of the V-Cal, such as a power on / off key, and date input keys (not shown) for setting the date input mode. That is, it is configured to apply a key signal corresponding to the key pressed by the user to the microcomputer 20.

The left / right shift keys (◀, ▶) 12 in the key input unit 10 are keys having a position shift function used for channel up / down, volume up / down, etc. of V-Cal and are pressed by the user. Outputs a key signal for moving the cursor to the corresponding date (year, month, day). The left and right shift keys 12 are applied because the numbers displayed on the television screen are arranged horizontally. If the date is arranged vertically, the up / down shift keys (▲, ▼) should be applied. something to do.

In addition, the enter key 14 in the key input unit 10 is a key for setting a corresponding date after moving the cursor using the left / right shift key 12 described above, and the date setting key signal as pressed by the user. Outputs

The microcomputer 20 according to the present invention selectively drives V-Cal in response to these key signals. In addition, the memory unit 30 is connected to the microcomputer 20, and a plurality of date display information is stored in the memory unit 30. Therefore, the microcomputer 20 reads out the date display information corresponding to the date input key signal from the key input unit 10 and outputs a character and numeric control signal to the display unit 40.

Hereinafter, with reference to the above-described configuration, with reference to the flowchart of Figure 2 attached to the date input process according to the present invention will be described in detail.

First, in step S100, the microcomputer 20 determines whether a date setting key signal for setting a date is applied from the key input unit 10.

As a result of the determination in step S100, when the date setting key signal is applied, the microcomputer 20 proceeds to step S102 to read the preset year indication information data in the memory unit 30 and display the year indication information. Outputs a control signal to the display unit 40. Therefore, the year display information as shown in Fig. 3A is displayed on the television screen. The year display information includes a plurality of years close to the current date (in this embodiment, five years are taken as an example), and the user can move to a desired year according to the input of the left / right shift key 12. .

After performing step S102, the microcomputer 20 proceeds to step S104 to determine whether a predetermined year is selected. That is, it is determined whether or not a key signal for selecting a predetermined year, for example, 97, from the enter key 14 is applied.

As a result of the determination in step S104, when a year selection key signal is input, the microcomputer 20 proceeds to step S106 to read out the month display information data preset in the memory unit 30 and display the month display information. Outputs a control signal to the display unit 40. Therefore, the wall display information as shown in Fig. 3B is displayed on the television screen. The month display information includes a plurality of months close to the current date (in this embodiment, five months are taken as an example), and the user can move to a desired month according to the input of the left / right shift key 12.

After performing step S106, the microcomputer 20 proceeds to step S108 to determine whether a predetermined month is selected. That is, it is determined whether the key signal for selecting a predetermined month, for example, November, from the enter key 14 is applied.

As a result of the determination in step S108, when the month selection key signal is input, the microcomputer 20 proceeds to step S110 to read out the preset one display information data in the memory unit 30 and display the one display information. Outputs a control signal to the display unit 40. Therefore, one display information as shown in Fig. 3C is displayed on the television screen. The day display information includes a plurality of days close to the current date (in this embodiment, five jobs are taken as an example), and the user can move to a desired day according to the input of the left / right shift key 12.

After performing step S110, the microcomputer 20 proceeds to step S112 to determine whether a predetermined work is selected. That is, it is determined whether a key signal for selecting a predetermined day, for example, 13 days, from the enter key 14 is applied.

As a result of the determination in step S112, when the work selection key signal is input, the microcomputer 20 displays the selected work display information and ends step S112. That is, all of the selected year, month and day information is displayed.

In addition, the flowchart described above is an exemplary date input process for setting the year, month, and day, and it is common knowledge in the technical field of the present invention that the time, minute, second, and channel setting can be sufficiently realized by applying this process. It will be easy to see who has it.

As described above, the present invention has the effect of simplifying the date key input of V-Cal and reducing the key input error.
