It includes a signal generator for sequentially generating each pulse signal for.

According to another preferred embodiment for achieving the above object, the present invention provides a V. C. R. using a V. C. / TV remote control for setting the mode of V. C. and TV when playing a specific program. A method for automatically setting a television mode, comprising the steps of: determining whether a playback command signal is input; determining whether a television mode setting signal sequentially input after a playback signal is received by the remote control signal receiver of the television; When the television mode setting signal is received, the television is switched to the A / V mode; otherwise, the television mode setting message is displayed, and the mode setting is judged to be in the mode setting, and the playback stop command signal is executed. Judging whether or not an input; If so, stopping playback and returning the television to its original mode.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 and 2 are block diagrams of an apparatus for executing a VCR / TV combined remote control and a mode automatic setting method using the same according to a preferred embodiment of the present invention.

As shown in FIG. 1, the VCR / TV-compatible remote controller 10 has a control signal according to an output signal of the key input unit 11 and the key input unit 11 for generating a key input signal input according to a user's intention. A microcomputer 13 for generating a signal, a memory 12 for storing data according to an output signal of a key input unit, and a signal generator 14 for sequentially generating a pulse signal according to a control signal generated from the microcomputer 13, respectively. ).

In addition, as shown in FIG. 2, the apparatus for executing the automatic mode setting method using the VCR / TV combined remote controller includes a VCR / TV combined remote controller 10, a first receiver 15, and a first controller 55. , V. 20, the first signal processor 25, V. C. 100 and the first switching unit 30, the second switching unit 35, the antenna 45, the second signal The TV 200 includes a processing unit 50, a display unit 60, an OSD processing unit 70, a mode switching unit 65, a second receiving unit 75, and a second control unit 80.

When a play command of a specific program is input through the key input unit 11, the microcomputer 13 reads the VCR and TV mode setting data stored in the memory 12 and provides a control signal accordingly to the signal generator 14. Then, the signal generator 14 first generates a pulse signal for switching the VCR 100 to the reproduction mode, and then sequentially outputs a pulse signal for sequentially switching the TV 200 to the A / V mode. Occurs at (15,75).

The mode switching signal received from the first receiver 15 is provided to the first controller 55, and the first controller 55 generates a control signal according to the deck unit 20 to reproduce the deck 20. Let it run

When the reproduction is executed, the deck unit 20 provides the reproduction signal to the first signal processing unit 25, and the first signal processing unit 25 processes and outputs the reproduction signal.

Meanwhile, at the same time, the second receiver 75 receives a pulse signal for mode switching provided from the remote controller 10 and outputs the pulse signal to the second controller 80.

Thereafter, the second control unit 80 generates a control signal to the mode switching unit 65, and the mode switching unit 65 transmits an 'on' signal to the first switching unit 30 and to the second switching unit 35. Provide an 'off' signal. As a result, the display 60 is tuned by the tuner 45 through the antenna 40, and the broadcast signal processed by the second signal processor 50 is in an unreceivable state, that is, an A / V mode state.

In this case, if the pulse signal generated by the remote controller 10 is a signal that cannot be recognized by the second controller 80, the second controller 80 causes the display unit 60 to display a character requesting TV mode setting. The control signal is generated to the OSD processing unit 70 and the display unit 60 displays these characters according to the output signal of the OSD processing unit 70.

When the TV 200 is in the A / V mode, the reproduction signal provided from the first signal processing unit 25 is displayed on the display unit 60 of the TV 200 through the first switching unit 30 in an 'on' state. Is displayed.

After the playback is completed, if the user's playback stop command is input to the key input unit 11 of the remote controller 10, the signal generator 14 of the remote controller 10 performs the same process as when the playback command signal is input. After that, pulse signals for reproducing stop are sequentially provided to the first receiver 15 and the second receiver 75.

At this time, the first receiver 15 of the VCR 100 receives the pulse signal generated by the remote controller 10 and provides it to the first controller 55. Thereafter, the first controller 55 issues a control signal for stopping playback to the deck unit 20 and the deck unit 20 stops playback in accordance with the control signal of the first controller 55.

On the other hand, the second receiving unit 75 of the TV 200 receives the pulse signal generated by the remote controller 10 and provides it to the second control unit 80, the second control unit 80 provides the control signal according to the mode switching unit Occurs as (65). Accordingly, the mode switching unit 65 generates an 'off' signal to the first switching unit 30 and an 'on' signal to the second switching unit 35 to return the mode of the TV 200 to its original state. It is in a state capable of receiving and displaying a broadcast signal provided through).

3 is a flowchart for executing a method for automatically setting a mode using a VCR / TV combined remote control according to the present invention.

In operation S10, the first controller 55 determines whether a reproduction command signal generated by the remote controller 10 is input through the first receiver 15. If it is not input in step S10, the flow is fed back and if it is input proceeds to step S20.

In step S20, it is determined whether the TV 200 mode setting signal sequentially generated after the reproduction command pulse signal is generated in the remote controller 10 is recognized by the second controller 80. If recognizable at step S20, the process proceeds to step S30, and if not, the process proceeds to step S40.

When the process proceeds from the step S20 to the step S20, in the step S30, the second controller 80 generates a control signal, switches the TV 200 to the A / V mode, and proceeds to the step S60. Perform playback. On the other hand, if proceeding from step S20 to step S40 in step S40 displays a message requesting the TV 200 mode setting, and again, after the TV mode setting signal for playback is input in step S50 The flow advances to step S60 to execute playback.

In step S70, it is determined whether the reproduction stop pulse signal is input through the remote controller 10. In step S70, if a reproduction stop signal is not input, the flow returns to step S60, and if input, the flow advances to step S80.

In step S80, playback of the VCR 100 is stopped, and thereafter, in step S90, the flow ends after the mode of the TV 200 is restored to its original state.

As described above, the present invention has the effect of simultaneously setting the TV and the VCR using only one input signal using the VCR / TV combined remote control and the mode automatic setting method using the same.
