Description

VCR playback control method according to PIP on / off status of video television

The present invention relates to a video television (TVCR). In particular, the PIP function is turned off while watching a video of a VCR on a picture-in-picture (PIP) screen, and the PIP screen disappears and the playback operation of the VCR is paused. Stops the VCR when a predetermined time elapses from the stop state, and when the PIP ON signal is input again within the predetermined time, the video television's PIP cancels the pause of the VCR to allow continuous playback. A method of controlling a VCR regeneration operation according to an on / off state.

In general, a video television refers to a video device in which a television and a video cassette recorder (VCR) are integrally formed. In recent years, products that add a PIP function to the existing video television have been developed to simultaneously view the received broadcast signal and the video signal read from the video tape. The method of controlling the operation of the video deck unit according to the display state of the PIP screen of the video television having the PIP function includes a video television system (TVCR) system for controlling the playback operation according to the PIP function setting filed by the same applicant on the same date. It is shown in the method. The above-described invention uses the PIP function of the video television to watch the TV broadcast signal on the mother screen, and removes the PIP display function (OFF) while watching the video signal of the VCR on the child screen (hereinafter referred to as PIP screen). The video television (TVCR) can control various operations of the VCR by setting the first case of stopping the playback operation of the VCR and the second case in which the playback operation of the VCR can be maintained even if the PIP screen disappears. The present invention relates to a system and a method thereof.

However, in the above-described technique, when the PIP screen disappears according to the PIP OFF signal and the playback operation of the VCR stops, the user wants to see the VCR signal again on the PIP screen. The deck section of the VCR had to input the PIP ON signal and the VCR playback operation signal (eg, the PLAY signal). In the second case as described above, that is, when the playback operation of the VCR is maintained according to the PIP screen off signal and only the PIP screen disappears, the VCR signal is reproduced as it is while the PIP screen is turned off. When you want to see again, the user had to return to the desired part through the key operation one by one.

Accordingly, the present invention, when displaying the signal from the VCR to the PIP in order to improve the above-mentioned problem, when the PIP screen off signal is input, the operation of the VCR is paused (PAUSE), and the PIP is turned on again within a predetermined time. When the (ON) signal is input, the VCR pauses to resume playback.If the PIP ON signal is not input again within a predetermined time, the video television's PIP stops the VCR. A method of controlling a VCR regeneration operation according to an on / off state is provided.

A feature of the present invention for achieving the above technical problem is a method of showing a TV broadcast signal and a VCR signal on a screen of a system having a PIP function, comprising: (1) displaying the TV broadcast signal on a mother screen; Displaying the VCR signal on its own screen; (2) when the PIP OFF signal for removing the PIP screen is input, the VCR screen display pause step of removing the PIP screen and pausing the screen display of the VCR signal; (3) counting time from the time when the screen display of the VCR is paused; And (4) if a PIP on signal showing the PIP screen is input within a preset time, performing screen display from the time when the screen display of the VCR is paused, and stopping displaying the screen of the VCR after a preset time. Steps are in the PIP screen control method of a video television comprising.

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

1 is a block diagram showing an apparatus for controlling a PIP screen of a video television including a pause function applied to the present invention.

As shown, the PIP function control apparatus of the present invention is a key input unit for generating a PIP function selection signal for selecting a PIP function, a channel selection signal for selecting a predetermined channel, and a video operation signal key input signal for controlling the deck unit. And a microcomputer 20 for generating data and a switching selection signal according to the key input signal of the key input unit 10. The microcomputer 20 includes a tuner unit 30 that tunes a desired broadcasting station channel by receiving data according to a channel selection signal and tunes a desired broadcasting station, and a deck for reproducing a VCR signal recorded on a video tape according to a video operation signal. The parts 40 are respectively connected. The tuner unit 30 and the deck unit 40 are provided with a switching unit SW for selecting and outputting signals from the tuner unit 30 and the deck unit 40 according to the switching selection signal of the microcomputer 20. . The switching unit SW receives one signal or two signals from the switching unit SW, and processes the mother screen image signal processing unit 50 and the mother screen image signal to process the mother screen image signal. It is connected to the mother screen image signal processing unit 60. The mother screen video signal and the mother screen video signal thus processed are synthesized and displayed on the CRT 70.

The PIP screen reproduction control method of the video TV including the pause function applied to the present invention configured as described above will be described in more detail with reference to FIG. 2.

An embodiment of the present invention will be described for the case of watching TV broadcasts on the parent screen and watching VCR broadcasts on the subscreen.

First, the microcomputer 20 checks the current display state of the CRT 70. The microcomputer 20 determines whether the PIP screen is displayed in a predetermined position of the mother screen (step 210). If the PIP is ON, the microcomputer 20 determines whether the VCR signal from the deck unit 40 is reproduced on the PIP screen (step 220). When the VCR signal is reproduced, it is regarded as a normal PIP operation. Otherwise, the process returns to step 210 again and repeats the step. Next, the microcomputer 20 determines whether a signal for deleting a PIP screen, that is, a PIP off signal, is input from the key input unit 10 (step 230). The microcomputer 20 receives a PIP off signal. If so, the control signal is output to the deck unit 40 to temporarily stop the playback operation of the deck unit 40 (step 240), and the PIP screen removal signal is output to the CRT 70. At the same time, the microcomputer 20 checks the time from the time point at which the deck unit 40 is suspended using the internal timer. However, if the PIP OFF signal is not input, the process returns to step 220 and repeats the step. As a result of the time check, the microcomputer 20 determines whether the predetermined predetermined time has passed (operation 250). If the predetermined time has not elapsed, the microcomputer 20 determines whether the PIP ON signal is input again (step 260). When the microcomputer 20 receives the PIP ON signal within a predetermined time, the microcomputer 20 outputs the VCR to the deck unit 40. Accordingly, the VCR signal is continuously displayed on the PIP screen (step 270). However, if a predetermined time has elapsed after the PIP screen is turned off, the microcomputer 20 outputs a playback stop signal for stopping the playback operation to the deck unit 40 (step 280).

As described above, the present invention relates to the control of the PIP function of a video television (TVCR). When watching the VCR signal from the deck unit through the PIP screen, the output of the video signal is paused when the PIP display function is turned off. When the predetermined time elapses in the state, the VCR is stopped, and when the PIP ON signal is input again within the preset disappearance time, the VCR is paused to continuously play the VCR so that the playback can be continued. PLAY, STOP, etc.) do not need to manually operate manually, it provides the advantage that can control the display of PIP screen through simple key operation.
