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 14 to the tuner unit 20, for example, the first tuner or the second tuner 20a or 20b (hereinafter described with reference to 20a). Will be authorized. Then, the first tuner 20a performs channel selection, and the voice 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 reproducing process performed by the voice signal processing section 26 is, for example, the volume adjustment set by the volume control button 10d of the control signal input section 10 or the voice 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 amplifying unit 34 is reproduced on the main screen of the CRT apparatus 35.

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 is applied from the control unit 12 to control the multi-screen processing at the time of selection, the image signals of the channels tuned by the first and second tuners 20a and 20b are different on a single screen. The CRT field is processed after being amplified by the image amplification unit 34. To 36 it is displayed in the main screen and sub-screen (36a), in this case the audio signal for the video signal of the main screen is to be played back through the speaker unit.

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 where registration of the multi-recording mode data is completed, the controller 12 starts recording of the main channel based on the time data counted by the timer 46 (step 19:00 in FIG. 2). When determining the arrival of '), the control unit 12 provides the switching signal SW so that the A / V switching unit 24 is routed to the tuner 20 side and the signal processing unit 42 side. The video signal and the audio signal are read from the channel data storage unit 14 to be tuned by applying the selected channel data corresponding to the reserved main channel ('9' in FIG. 2) to the first tuner 20a. It is processed by the processing of and recorded on the video tape T by the signal processing section 42 and the signal recording / reading section 40 through the A / V switching section 24 (step 74). In step 74, the control unit 12 causes the audio signal for the channel to be recorded on the video tape T for the time designated by the recording mode data (ie, 19:00 to 20:30).

When the recording time of a subsequent channel (i.e., PIP channel; '7') arrives during the execution of such recording, the controller 12 determines the recording mode for the subsequent channel and determines that the PIP mode ( YES in step 76), the control unit 12 controls the image multi-processing unit 32 to record the PIP channel as a sub picture similarly to the signal processing of the PIP processing function in step 78. When the voice recording time for the channel arrives (ie, 20: 30-21: 00 in FIG. 2), the A / V switching unit 24 is controlled to record the voice signal for the PIP channel.

Subsequently, in step 80, when the recording end time for the main channel and the subchannel arrives, the controller 12 sequentially stops recording to complete the control of the recording.

As described above, according to the multi-tuner tele-video recording apparatus and method thereof according to the present invention, the TV of the main channel and the sub-channel by the 2-tuner is operated by the operation of the multi-recording button provided in the control signal input unit. The multi-screen processing function of televideo can be diversified by recording the video / audio in the designated form of the main screen and the sub screen by PIP method and recording the audio signal independently by specifying the recording time.
