Control Method of VCR Power Supply by Tele Video Power Key Operation

The present invention relates to a method of controlling a VCR power supply by operating a power key of a televideo, and more particularly, to a component circuit on the television side and a VCR side according to an operation state of a power key in a televideo in which a television and a VCR are integrated. The present invention relates to a VCR power supply control method by operating a power key of a televideo to allow power supply between components to be differentially performed.

Conventionally, a video cassette tape recorder (hereinafter referred to as a VCR) performs an operation of reproducing a video signal and an audio signal recorded magnetically on a video tape, and a television is transmitted wirelessly or by wire from a broadcasting station. Video and audio playback of video and audio signals of broadcast programs or video and audio playback of video and audio signals transmitted from an external video playback device, such as a VCR. The video / audio signal is interconnected by a transmission cable so that the video / audio signal for a video mode or a program of a television broadcast is reproduced.

That is, in the past, the television and the VCR are configured as independent components to exchange video / audio signals by means of a connecting cable, but at present, the playback function of the video / audio signal of the television and the video / audio signal of the VCR are reproduced. And a tele-video (TVCR) with a mixed recording function has been developed and commercialized.

According to such a televideo, a tuning function for tuning a broadcast program transmitted from a plurality of broadcast stations, a channel memory function searched by the tuning function, and recording of a video / audio signal or videotape according to a broadcast program of a tuned channel The playback function of video / audio reproduction of information and the recording function of the video tape on the recording surface are integrated.

On the other hand, the function setting means for keying the execution of the function operation of the tele-video is composed of a control panel formed on the front of the tele-video or a remote control for remote control of the tele-video, the overall functional operation that can be performed on the television and VCR The power supply of the television and the VCR are turned on at the same time, especially when the user operates the power key of the televideo on the control panel or the remote control to watch a picture played on the television or the VCR. It will work.

In such a case, even when the power key is turned on for watching and broadcasting a television broadcast signal of a predetermined channel by a television function, the power supply of the VCR is also turned on so that a loading operation for preparing to drive the video tape is performed. do.

In this case, however, even when the video tape is not played back through the VCR, the VCR side turns on every time the televideo power key is turned on, which wastes unnecessary power and shortens the life of the VCR. To act as the main cause.

Accordingly, the present invention has been made in view of the above-described circumstances, and in response to the operation continuity state at the time of performing the key operation for turning on the power supply of the televideo from the function setting means, the common power of the television power supply and the VCR power supply It is an object of the present invention to provide a VCR power control method by operating a power key of a tele video to enable on or differential on operation.

In order to achieve the above object, according to the VCR power control method by operating the power key of the televideo according to the present invention, in the televideo in which the functions of the television and the VCR are mixed, the operation of the televideo by the key operation of the function setting unit is performed. A first step of turning on the power, a second step of determining whether the input period of the key data signal according to the power-on operation of the function setting unit has elapsed to the first setting period (flag 1), and the input period of the key data signal When the first set period (flag 1) has elapsed, the third step of differentially turning on the television side operation unit, and the input period of the key data signal according to the power-on operation of the function setting unit is the second set period (flag 2). 4th step of determining whether or not to continue, and if the input period of the key data signal has elapsed to the second setting period (flag 2), the VCR side operation section and power on operation are additionally executed. Is that is is made of a fifth step it provides the VCR power supply control by the key operation of the video telephone method.

According to the present invention made as described above, when the power key of the televideo is operated, only the television side power supply is discriminated when the operation duration of the power key corresponds to the flag setting period for the independent power-on operation of the television power source alone. When the power supply key operation duration is set to the flag setting period for the common power-on operation of the television side and the VCR side, the common power-on operation is enabled.

Next, referring to the flowchart of FIG. 2, a VCR power control method using a tele video power key operation will be described.

First, in step 100, the television microcomputer 12 detects whether the power key 10A is keyed from the function setting unit 10 and a signal for turning on the operation power of the televideo is applied. When a key data signal indicative of the power-on from the function setting unit 10 is applied, the process proceeds to step 102.

Subsequently, in step 102, the flag set by the key data signal applied to the televideo from the function setting unit 10 is reset before the key data signal indicating power-on is applied, and the flow proceeds to step 104. In step 104, it is determined whether the input period of the key data signal according to the power-on operation of the function setting unit 10 has passed to the first setting period (flag 1).

As a result of the determination, when the input period of the key data signal has passed to the first setting period (flag 1), the flow advances to step 106 to control the switching unit 19A to be driven on by the television microcomputer 12 so as to discriminate the television side operation unit. Power on.

Then, the television microcomputer 12 proceeds to step 108 to determine whether the input period of the key data signal according to the power-on operation of the function setting section 10 continues to the second setting period (flag 2). If the input period of the key data signal does not continue to the second set period (flag 2) as a result of the determination, the flow advances to step 109 to maintain the differential power-on driving state of only the television side operation portion.

As a result of the determination, when the input period of the key data signal has passed to the second setting period (flag 2), the flow advances to step 110, and the television microcomputer 12 controls the switching unit 19B to operate the television side in step 104. The negative power on operation is controlled so that the VCR side operation portion and the power on operation are additionally performed.

In step 112, the tape embedded judgment unit 21 detects whether or not the video tape is embedded in the tele-video and applies it to the television microcomputer 12 so that the television microcomputer 12 determines what the detection signal indicates. If it is determined that the videotape is inherent, the flow advances to step 114 to load the videotape, and if it is determined that the videotape is not embedded, the flow proceeds to step 116.

Subsequently, in step 116, the power source of the television and the VCR side of the televideo are differentially driven to perform a variety of operations of the televideo.

As described above, according to the present invention, in response to the function input state for the power-on operation of the televideo, the power supply of the television and the power supply of the VCR can be set differently by one key operation. Whenever the power is on, the power-on operation on the television side and the power supply of the VCR are turned on repeatedly, thereby eliminating the lifespan factor and unnecessary power waste of the VCR.
