Next, the method of the present invention applied to a composite product having the above configuration will be described.

In the method of the present invention, first, as shown in FIG. 3, the process proceeds from the initial state S1 to the mode signal determination step S2 to determine whether the present VR mode is set. As a result of the determination during the mode signal determination step (S2), if the CD mode is not set, the CD mode is set in the system, and the process proceeds to the CD mode execution step (S3) to execute the normal CD mode.

That is, when the CD playback mode is set, the microcomputer 2 recognizes this and drives the CD deck 1 to reproduce the CD signal. In this case, the video output selection switch 4 and the audio output selection switch 5 are connected to the CD. The switching is switched to the deck 1 side. Therefore, the microcomputer 2 drives the spindle motor 14 through the servo control unit 15, thereby causing the disk 6 to rotate. At the same time, the optical pickup 7 detects the information signal contained in the TOS of the disc 6 and inputs it to the RF amplifier 8. Then, the RF amplifier 8 amplifies the input detection data signal to a predetermined level and inputs it to the digital signal processor 9. In addition, the digital signal processing unit 9 inputs the digital signal of the VCD (VCD) input thereto, for example, it is subjected to demodulation and error correction, and then input to the microcomputer 2. Then, the microcomputer 2 judges the signal of the input disk 6 and determines what kind of disk is the disk currently mounted in the tray. The microcomputer 2 reads and stores the disk track information contained in the TOS of the determined disk 6 in sequence. For example, the contents of the tracks ENTRIES.VCD and LOT.VCD and PSD.VCD are sequentially read. Store in the RAM. Then, the microcomputer 2 inputs the data control signal of the VCD to the MPEG video / audio decoder 11 and accordingly the MPEG video / audio decoder 11 receives the compressed video input from the digital signal processor 9. And the audio data signal is restored and input to the video and audio signal processing units 12 and 13, respectively. The audio data signal input to the audio signal processing unit 13 is low frequency amplified and then the audio output selection switch 5 Is output to the outside through the speaker 21, and at the same time, the image data signal is also processed by the image signal processing unit 12 and then the image output selection switch 4 is synchronized with the audio signal to display the display ( 20) is displayed as an image signal.

However, as a result of the determination during the mode signal determination step S2, if the BC mode is set, the process proceeds to the recording function setting determination step S4 to determine whether the recording function is set in the BC AL deck. When the recording function is not set in the BC RDK as a result of the determination during the recording function setting determination step (S4), the process proceeds to the execution of the VR playback function (S5) and executes the set BC playback function. However, if it is determined during the recording function setting determination step (S4) that the recording function is set in the BC Al deck, the process proceeds to the BC recording function execution step (S6) to execute the set BC recording function.

That is, the video tape is loaded on the BC Aldek (3) and the set information, for example, to record a TV broadcast signal, etc. At this time, the microcomputer (2) is a tuner unit (video input switch 18 and audio signal input switch 19) 22) is switched. Accordingly, the video signal and the audio signal of the broadcast signal tuned by the tuner unit 22 are input to the BC Aldeq 3 through the video input switch 18 and the audio signal input switch 19. Then, this BC3 deck records the broadcast signal of the tuner unit 22 input through the video input switch 18 and the audio signal input switch 19 on the video tape.

On the other hand, after the execution of the BCD recording function (S6) proceeds to the audio dubbing mode setting determination step (S7) and the audio dubbing mode (AUDIO DUBBING MODE) in the current system, for example, the music information of the CD (CD) on the recorded video screen It is determined whether a setting signal for setting a voice dubbing mode for dubbing is input. As a result of the determination during the voice dubbing mode setting determination step S7, if the setting signal for setting the voice dubbing mode is not input, the process returns to the previous step S6 to repeat the loop. However, if the setting signal for setting the voice dubbing mode is input as a result of the judgment during the voice dubbing mode setting determination step (S7), the process proceeds to the voice memo insertion function determination step (S8) while executing the voice dubbing mode in the current system. It is determined whether the voice memo insertion function for recording the voice memo signal in the voice track of the video tape is set. When the voice memo insertion function judging step (S8) is judged and if the voice memo insertion function is not set, the procedure proceeds to the general dubbing function execution step (S9) and the music of the CD is recorded on the recorded video screen without inserting the voice memo. Only dubbing information.

That is, when the audio dubbing function for recording only the audio signal of the CD in the audio track of the video tape on which the video signal is recorded is executed, the VCD and the deck 1 have the video tape and the tape. When the CDs are respectively mounted and the voice dubbing switch of the key input unit 17 is set, the microcomputer 2 recognizes this and connects the voice signal input switch 19 to the CD deck 1 side to output the voice signal of the CD deck 1. The switching is switched so as to be input to the VCD deck 3, the image input switch 18 connected to the CD deck (1) is blocked. At the same time, the microcomputer 2 connects the video output selection switch 4 to the VCD deck side, and the audio output selection switch 5 to the CD deck 1 side. Then, the microcomputer 2 drives the VCD deck 3 to execute the voice dubbing function and simultaneously drives the CD deck 1. Therefore, CD (CD) sound inputted via the audio signal input switch 19 from the CD deck 1 into the audio track of the recorded video tape currently being reproduced by the VCD deck, for example, music information is recorded. Will be.

However, if the voice memo insertion function is determined during the voice memo insertion function judging step (S8), if the voice memo insertion function is set, the voice memo dubbing function execution step (S10) proceeds to the user's voice memo in the initial voice track of the recorded video tape. After recording the signal for a predetermined time, the music information of the set CD is dubbed.

That is, the voice of the key input unit 17 is executed when the voice memo dubbing function of recording the voice signal of the CD is recorded after recording the voice memo signal of the user in the initial voice track of the video tape on which the video signal is recorded. When the memo dubbing switch is set, the microcomputer 2 recognizes this and connects the video output selection switch 4 to the VCD deck 3, and the audio output selection switch 5 to the CD deck 1 side. In addition, the microcomputer 2 drives the VLC deck 3, in which the voice memo signal of the user stored in the memory unit 25 is currently recorded on the VCD deck. AUDIO TRACK). For example, the recorded voice memo signal is recorded as an audio signal in the form of describing the recording contents of the video tape. After the voice memo is dubbed into the initial voice track of the video tape, the microcomputer 2 connects the voice signal input switch 19 to the CD deck 1 side so that the voice signal of the CD deck 1 is 3) to switch the input so that the image input switch 18 connected to the CD deck (1) is blocked. Therefore, CD (CD) sound inputted via the audio signal input switch 19 from the CD deck 1 into the audio track of the recorded video tape currently being reproduced by the VCD deck, for example, music information is recorded. Will be.

Here, the voice memo of the voice memory unit 25 is stored through the microphone 24.

Therefore, when the user plays the video tape dubbed the voice memo as described above, the recording contents of the video tape dubbed the CD sound can be easily watched along with the voice memo of the user.

As described above, the present invention provides a voice memo signal of a user by providing a voice memory unit capable of memorizing a user's voice signal and recording the voice memo signal of the user in an initial voice track of a video tape recorded during audio dubbing. It can be recorded along with the recorded contents of the video tape, thereby improving the functionality of the system.
