Next, the multi-recording control method executed by the 2-tuned televideo multi-recording control apparatus according to the present invention will be described in detail with reference to the flowchart shown in FIG.

First, when the control unit 12 receives the control signal provided from the control signal input unit 10 in step 60, the control signal is a control signal generated by operating the multi-recording button 10b in step 62. If it is determined that the control signal is not a control signal by the operation of the multiple recording button 10b, the process proceeds to step 64 to determine whether it is a signal for setting the VCR mode by the operation of the mode selection button 10a. If it is determined that the control signal is not a control signal for setting the VCR mode, the process proceeds to step 66 where the video / audio signal reproduction processing under the normal TV mode is performed.

That is, according to the reproduction processing of the video / audio signal in the normal TV mode, the control unit 12 receives a signal for reproducing a broadcast program provided from the tuner 20 to the A / V switching unit 24. The switching control signal SW is applied to form a processing path, and then the channel selected / last memorized by the channel up / down button 10c or the 10-key 10e of the control signal input unit 10 is selected. To read the corresponding tune data from the channel data storage unit 14 to perform the first tuner or the second tuner 20a or 20b (described below with reference to 20a) of the tuner 20, Will be authorized. Then, the first tuner 20a performs channel selection, and the audio signal of the tuned channel is IF converted by the voice IF module 22 to perform a voice signal through the A / V switching unit 24. It is provided to the processing unit 26 to be reproduced. The audio signal reproduction processing performed by the audio signal processing section 26 is performed by adjusting the volume set by the volume adjustment button 10d of the control signal input section 10, or by audio multiplex processing (stereo mode or multilingual broadcasting processing, etc.). Is included, and the voice signal processed by the voice signal processor 26 is amplified by the voice amplifier 28 and applied to be reproduced by the speaker device.

On the other hand, the video signal of the channel tuned by the first tuner 20a is IF-converted by the first video IF module 30a and applied to the video multi-processing unit 32 through the A / V switching unit 24. The image multiple processor 32 processes the image signal based on an image processing control signal (eg, brightness / contrast adjustment, etc.) provided from the control signal input unit 10 with respect to the image signal. The image signal amplified by the image amplifier 34 is reproduced on the main screen of the CRT apparatus 36.

In such a state, when the multi-screen processing by the PIP function is selected in the control signal input unit 10, the control unit 12 under the PIP function while the first tuner 20a maintains the current channel selection. The channel data storage unit 14 reads out the selected second channel and applies it to the second tuner 20b, and the video signal of the channel tuned by the second tuner 20b is the second image. IF converted by the IF module 30b and applied to the image multiple processing unit 32 via the A / V switching unit 24. The image multiple processing unit 32 has a PIP of the control signal input unit 10. When the control signal CS for controlling the multi-screen processing is applied from the control unit 12 when selecting, the video signals of the channels tuned by the first and second tuners 20a and 20b are different on a single screen. After being processed into a screen and amplified by the image amplifier 34, The main screen and the sub-screen 36a are displayed on the CRT device 36. In this case, the audio signal for the video signal of the main screen is reproduced through the speaker device.

When the control signal inputting of the video / audio signal is input from the control signal input unit 10 when the video signal and the audio signal are reproduced under such a TV mode, the controller 12 controls the OSD processor 16 to correspond to the corresponding signal. An OSD signal relating to a control state is generated and applied to the image multiple processor 32, and the image multi processor 32 inserts the OSD signal into a programmatically determined position. Through the CRT device 36 to be reproduced.

In contrast, when the VCR mode is selected by the mode selection button 10a of the control signal input unit 10 as a result of the determination in step 64, the control unit 12 performs the A / V switching unit 24 in step 68. The switching control signal SW is applied to control the signal path to be switched to the external video signal and the audio signal (A / V signal) provided from the video tape recorder (VCR) side. The audio signal is reproduced by the audio signal processor 26, the audio amplifier 28, the image multiple processor 32 and the video amplifier 34, and reproduced on the speaker device and the CRT device 36.

On the other hand, if it is determined in step 62 that the control unit 12 is a control signal by the operation of the multi-record button 10b to the main channel and / or sub-channel set by the 10-key (10e) in step 70 The recording start time and the recording end time are received and stored in the data storage 44 in the format shown in FIG.

Subsequently, in the state in which the multi-recording mode data is registered, the control unit 12 starts recording of the main channel based on the time data counted by the timer 46 in step 72 ('18: 30 in FIG. 2). When the start time of recording for the main channel is reached (YES in step 72), the controller 12 determines that the A / V switching unit 24 is connected to the tuner 20 side. In addition to providing a switching signal (SW) to be routed to the signal processor 42 side, the channel data storage unit 14 reads preset data corresponding to the reserved main channel ('9' in FIG. 2). By applying to the first tuner 20a to be tuned, the video signal and the audio signal are processed by the signal processing unit 42 and the signal recording / reading unit 40 through the A / V switching unit 24. Is recorded on the video tape T (step 74).

In such a state, the control unit 12 determines whether the recording start time ('19: 05 'in FIG. 2) for the subchannel (' 13 'in FIG. 2) arrives or not. If it is determined that the recording start time for the subchannel is detected (YES in step 76), the control unit 12 performs the subchannel similarly to the signal processing process by the PIP function in step 78. The channel data for is read by the channel data storage unit 14 and applied to the second tuner 20b.

Accordingly, the video signal of the main channel and the sub channel and the audio signal of the main channel tuned by the first and second tuners 20a and 20b are transmitted to the signal processor 42 through the A / V switching unit 24. The multi-screen video signal and the audio signal processed by the signal processor 42 are applied to the video tape T through the signal recording / reading unit 40 to perform the multi-recording process.

Subsequently, in step 80, the controller 12 determines the arrival of the recording end time for the main channel, for example, and controls the A / V switching unit 24 while stopping recording of the main channel. A video signal of a subchannel is switched to be processed as a signal of the main screen, and a control signal CS is applied to the video multiprocessor 32 to control the video signal of the subchannel to be processed as a main screen. The OSD processing unit 16 generates an OSD signal related to screen switching. Accordingly, the video tape T switches from the time point at which the main channel recording ends to the sub channel to the main screen, thereby generating the OSD signal. The insertion process is performed so that the guidance signal for switching the screen is also recorded for a predetermined time (step 82).

As described above, according to the two-tuner tele-video multi-recording control apparatus according to the present invention, TV video / audio of the main channel and sub-channel by the 2-tuner by the operation of the multi-recording button provided in the control signal input unit If the recording is set in the multi-screen mode by the PIP method with different recording times, the screen is automatically released by only canceling the multi-screen processing function when the recording of any one channel ends. The recording effect of the can be improved.
