The present invention relates to a mode switching control method for tele video. More specifically, if a TV mode is set while performing a playback operation on a video tape in a VCR mode, the STILL mode is set and then set in such a state. The present invention relates to a mode switching control method in a tele video which enables to set a stop mode for the playback operation when time passes.

Televisions for reproducing and outputting video signals and audio signals included in broadcast signals transmitted from a broadcasting station are signal-coupled to a video tape recorder (VCR) or a laser disc player (LDP) and reproduced on a video tape or a laser disc. It is also used as a video and audio output device for audio and audio signals. Conventionally, a VCR, which is a playback device for video and audio signals, and a television coupled to the VCR are configured as independent entities, but recently designed to have a complex function. The state of the television (TVCR) by combining the television and the VCR has been proposed.

On the other hand, a predetermined video tape is inserted into the video tape storing unit of the above-described tele video, and then a playback mode is performed for the video / audio signal recorded on the video tape by setting a playback mode for the video tape. When the TV mode is set for confirmation, the broadcast signal for any channel in the TV mode is output through the speaker of the corresponding televideo and the CRT, but at the same time, the playback processing for the video / audio signal recorded on the video tape is performed. Since this state is continuously performed, the user has a problem that the video / audio signal from the video tape reproduced during the channel check cannot be viewed.

Therefore, in this state, the playback processing operation for the video / audio signal recorded on the videotape is performed unnecessarily. Therefore, it is preferable to stop the playback processing operation. In this case, it is necessary to operate a predetermined key for setting the 'stop' mode for playing the video tape, and then operate a predetermined key for setting the TV mode, and then operate a predetermined key for tuning the channel to be watched. There was a hassle.

In addition, in order to retry the playback of the videotape in the TV mode, the user must switch to the VCR mode and operate the predetermined key for setting the 'playback' mode to set the play mode to read the video / audio read from the videotape. Since the signal is reproduced and output through the CRT and the speaker of the corresponding televideo, it was troublesome to perform the key operation several times.

Accordingly, the present invention has been made in view of the above circumstances, and when the TV mode is set during the playback operation on the video tape in the VCR mode, the STILL mode is set and when the predetermined time elapses in such a state, It is an object of the present invention to provide a mode switching control method in televideo, which enables to set a stop mode for a playback operation.

A method of controlling mode switching in televideo according to an embodiment of the present invention applied to televideo having the above-described configuration will be described in detail with reference to the flowchart shown in FIG. 2.

First, when the playback mode is set after the video tape is inserted into the video storing unit in the state in which the VCR mode is set by the mode switching key 10a configured in the control signal input unit 10, the control unit 12 controls the video tape T. Perform a playback operation for step (step 60).

That is, in step 60, the controller 12 performs a playback operation on the video tape T based on the playback signal input from the control signal input unit 10. The controller 12 performs the tape driving mechanism 44. Read the video / audio signal recorded on the videotape T by the head configured in the signal recording / reading unit 46 in a state in which the videotape T travels while maintaining the normal speed. The video / audio signal read out from the signal recording / reading unit 46 is controlled through the video / audio signal processing unit 48 and the A / V switching unit 24 and the audio signal processing unit 26. The image signal processor 30 is applied. At this time, the audio signal processor 26 reproduces the video signal read from the video tape T based on a control signal applied from the control signal input unit 10, for example, a specific control signal such as volume or audio surround. The voice signal is amplified by the voice amplifier 28 and then reproduced through the speaker SP.

In addition, the video signal read from the video tape T is processed as a signal for outputting the screen by the video signal processor 30, amplified by the video amplifier 28, and then output through the CRT apparatus.

As described above, when the control unit 12 controls the tape drive mechanism 44 to perform a function control according to the playback or rewinding / rewinding of the video tape T, the control unit 12 controls the tape driving mechanism 44. Time data relating to the rewinding / rewinding of the video tape T is displayed on the display section 42.

As described above, while performing the playback operation on the video tape 4, the controller 12 determines whether the TV mode is set by the control signal input unit 10 (step 62). As a result, the control signal input unit ( If it is determined by 10) that the TV mode is not set (NO in step 62), the process proceeds to step 60 to continuously perform the playback operation on the video tape T.

On the contrary, if it is determined by the controller 12 that the user desires to listen to the broadcast signal and sets the TV mode using the mode switching key 10a configured in the control signal input unit 10 (step; 62; YES) The control unit 64 applies a predetermined control signal to the tape driving mechanism 44 to the A / V switching unit 24 in a state in which a pause mode for the video tape T is set. The audio / video signal output from the audio / video IF module 20 or 22 is output by the A / V switching unit 24 by applying a predetermined switching signal SW, respectively, to the audio signal processor 26 and the video signal processor. A switching operation is performed to be applied to 30 (step 64).

In such a state, when the channel up / down signal is input from the control signal input unit 10, the control unit 12 reads out channel tuning data corresponding to the channel tuning signal from the channel data storage unit 14, and then the channel. Up / down tuning for the channel is performed by applying a predetermined tuning voltage VT to the tuner 18 based on the tuning data (step 66).

Then, the control unit 12 performs a reproduction processing operation on the broadcast signal of the tuned channel (step 68). In step 68, the voice signal of the specific channel tuned by the tuner 18 is transmitted to the voice IF module 20. Extracted by IF) and then converted to IF and then applied to the voice signal processing unit 26 via the A / V switching unit 24, and the voice signal processing unit 22 sets the volume control signal set through the control signal input unit 10. Alternatively, the voice signal is processed and applied to the voice amplifier 28 based on the voice multiple control signal, and the voice signal amplified by the voice amplifier 28 is applied to the speaker SP for reproduction.

In addition, the video signal of the channel tuned by the tuner 18 is extracted from the video IF module 26, IF converted, and then applied to the video signal processor 28 via the A / V switching unit 24. The video signal processing unit 28 performs RGB processing for reproducing the video signal, and performs insertion processing of the OSD text signal provided by the OSD processing unit 16 under the control of the control unit 12 to perform the corresponding video signal. Is applied to the image amplifier 32, and the image signal amplified by the image amplifier 32 is output on the CRT apparatus.

The control unit 12 determines whether the VCR mode is reset by the control signal input unit 10 while performing the reproduction processing operation on the broadcast signal of the channel selected as described above (step 70). In order to stop the operation and to reset the VCR mode, the controller 12 operates the mode switching key 10a configured in the control signal input unit 10 so that the control signal is inputted to the control unit 12. According to the determination result YES in 72, the process proceeds to step 71 to release the pause mode set in step 64, and then proceeds to step 60 to perform the playback operation on the video tape T. FIG.

On the contrary, if the VCR mode is not set in step 70 (NO), the control unit 12 determines whether a predetermined time has elapsed (step 72), and if the predetermined time has elapsed without setting the VCR mode (step 72). YES in step 72) The control unit 12 applies a predetermined control signal to the dap driving mechanism 44 and the signal recording / reading unit 46 to set a stop mode and then ends all processes (step YES). ; 74).

Therefore, if the user sets the TV mode to listen to the broadcast signal for a while while the video tape is being played, the pause mode for the video tape is automatically set and fixed even if the user does not set the pause mode manually. When the VCR mode is reset within the time, the preset pause mode is canceled and the playback operation on the video tape is performed.

If the VCR mode is not reset within the predetermined time, the stop mode is automatically set even if the user does not manually set the stop mode for the video tape T, and playback of the video tape T is stopped.

As described above, according to the mode switching control method of the tele-video according to an embodiment of the present invention, while the user plays the video tape in the VCR mode, the channel is checked in the TV mode, and then again in the VCR mode within a predetermined time. When the videotape is to be played, the pause mode is automatically set even without any key manipulation to provide the user with convenience, and the contents of the videotape can be prevented from passing during the channel check.
