It is characterized by being carried out with a step.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

1 shows a block diagram of the hardware of the calendar checking apparatus according to the present invention.

As shown in the figure, the hardware device to which the present invention is applied is provided with a button and a jog / shuttle switch necessary for checking a calendar, and when the switch is operated, a remote control transmitter 1 for outputting a corresponding key code; The remote controller receiver 2 classifies and outputs the corresponding key codes outputted from the remote controller transmitter 1, and performs the corresponding calendar checking function according to the key codes classified and thrusted by the remote controller receiver 2, and text data for the calendar. And a OSD circuit 4 for superimposing a text signal on the video signal to display text on the OSD screen according to the text data received from the controller 3.

Here, the controller 2 may be implemented as a timer microcomputer that processes a key input signal and controls an OSD function.

FIG. 2 is a detailed functional block diagram of the controller 3 shown in FIG. 1 and includes a mode changeover switch 21, a function controller 22, a month setting unit 23, and a year setting unit 24. .

The function control unit 22 receives a shuttle input and a calendar mode setting key input signal among the output signals of the remote control receiver 2, and determines whether to set the calendar confirmation mode by a function selection signal, that is, the calendar mode setting key input. In the calendar confirmation mode, the shuttle input determines whether the month setting mode or the year setting mode is selected.

Initially, it is set to month setting mode. In that state, year and month setting mode is toggled by shuttle input.

The mode switching switch 21 receives an operation control signal from the function control unit 22 and switches the jog input signal input from the remote controller receiving unit 2. The signal flow according to the switching operation is as follows.

That is, as shown in the figure, when the jog input terminal is connected to the terminal a of the switch 21, the corresponding processing is performed when a function mode other than the calendar confirmation function is selected.

When connected to the terminal b, the jog input is transmitted to the month setting unit 23, and when connected to the terminal c, the jog input is transmitted to the year setting unit 24.

The month setting unit 23 increases or decreases the month according to the jog input, and changes the year when the year is required to be changed.

The year setting unit 24 increases or decreases only the year within the range of 100 years according to the jog input, and sets the month of the set year to January.

The calendar calculation unit 25 calculates the calendar for the year and month set by the month setting unit 23 and the year setting unit 24.

The calendar confirmation apparatus according to the present invention configured as described above will be described in more detail with reference to the flowchart of FIG. 3 showing the overall processing of the calendar confirmation method.

First, in step S1, it is determined whether or not a function selection input, that is, an operation signal of a calendar mode setting key, is input from the remote control receiver 2.

When the operation signal of the calendar mode setting key is input, it is determined whether or not it is in the calendar confirmation mode (step S2).

As a result of the determination (S2), if it is not in the calendar confirmation mode, it is set to the calendar confirmation mode and the current year and month are set (step S3).

Then, in the determination result, in the calendar confirmation mode, the execution of the calendar confirmation mode is terminated, and the changeover switch 21 controls the state of the switch to perform another function mode (step S4).

After performing the above steps (S3, S4), if the calendar check mode state, the OSD text data of the calendar of the month is created and outputted and terminated. If the calendar check mode is not, the data for clearing the OSD unit 4 is terminated. (Steps S15 to S17).

On the other hand, as a result of the determination (S1), if the operation signal of the calendar mode setting key is not input from the remote control receiver 2, it is determined whether a shuttle input is provided (step S5). It is judged whether or not (step S6).

If it is in the month confirmation mode, it sets to the year confirmation mode, controls the changeover switch 21 so that a jog input signal is input to the year setting part 24, and ends (step S8).

However, if it is not in the month confirmation mode state, it is set to the month confirmation mode state and ends (step S7).

If the signal from the remote control receiver 2 is not a shuttle input signal, it is determined whether a jog input signal is provided (step S9).

If it is not the jog input signal, the process ends. When the jog input signal is provided, it is determined whether it is in the month confirmation mode (step S10).

At this time, if it is in the month check mode, the month is increased or decreased (step S12), and if the year setting is necessary, the year change is performed (step S14).

However, if it is not in the month confirmation mode, the month is set to January and the year is increased or decreased (step S11).

After performing the above steps (S11, S13), it is determined whether or not the calendar check mode state (step S15), if the calendar mode state, the OSD text data of the corresponding month calendar is created and outputted, and ends (step S16). If it is not in the calendar check mode, the data for clearing the OSD unit 4 is output and ends (step S17).

4 is a diagram illustrating an output display state of the OSD unit 4 according to the control of the present invention. For the guidance of the shuttle input, the OSD unit 4 can display only 10 lines of text data. Do it.

Therefore, the present invention made by the above-described configuration and processing procedure has the effect of facilitating the calendar confirmation function in the VTR.
