Here, the CD 6 includes a lead-in area L1 in which overall disk information is recorded, a program area PA in which actual information is recorded, and a lead-out area LO for indicating completion of reading of information contained in the CD. It is configured to include).

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

The method of the present invention first proceeds to the mode signal determination step S2 in the initial state S1 as shown in FIG. 3 to determine whether the current VR mode is set. In addition, if it is determined during the mode signal determination step S2 that the CD mode is not set, the system is set to the CD mode, 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 play the CD signal. At this time, 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 digitally processes the digital signal of the input VCD, for example, EFM demodulation and error correction, and then inputs it 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 order. For example, the contents of the tracks ENTRIES.VCD and LOT.VCD and PSD.VCD are sequentially read. Save to 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 inputs the compressed video input from the digital signal processor 9 and the like. The audio data signal is restored and input to the video and audio signal processing units 12 and 13, respectively. Then, the audio data signal input to the audio signal processor 13 is amplified low frequency and then output to the outside through the speaker 21 via the audio output selection switch 5, and at the same time the video data signal is also a video signal processor. The video signal is processed by (12), and then synchronized with the audio signal, via the video output selection switch (4), and displayed as an image signal via the display (20).

However, as a result of the determination during the mode signal determination step S2, if the VCR mode is set, the process proceeds to the recording function setting determination step S4 to determine whether the recording function is set on the VCR 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 execution of the BC R playing function is performed by executing the BC R playing function execution step S5. When the recording function is set in the BC RDK as a result of the determination in the recording function setting determination step S4, the execution of the BC recording function is performed by executing the BC recording function execution step S6.

That is, the video tape is loaded on the BC Aldek 3 and recorded information, for example, a TV broadcast signal is recorded. At this time, the microcomputer 2 sets the video input switch 18 and the audio signal input switch 19 to the tuner unit ( 22. Thus, the video signal and the audio signal of the broadcast signal tuned by the tuner unit 22 are transferred through the video input switch 18 and the audio signal input switch 19. Will be entered. Then, the BC Aldek 3 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 an audio dubbing mode for dubbing is input. As a result of the determination during the audio dubbing mode setting determination step (S7), if the setting signal for setting the audio dubbing mode is not input, the process returns to the previous step (S6) to repeat the loop. However, as a result of the determination during the audio dubbing mode setting determination step (S7), if a setting signal for setting the audio dubbing mode is input, the process proceeds to the multi-channel voice message selection determination step (S8) and various voice message signals stored in the memory means. Is displayed as a text signal on the display, and it is judged from among the display data that a suitable voice message signal to be recorded in the audio track of the current recording scene is selected. In the multi-channel voice message selection judging step (S8), when a suitable voice message signal to be recorded in the audio track of the current recording scene is not selected among the various voice message signals stored in the memory means, that is, the user hears the CD sound. If you want to dub only, proceed to the normal dubbing mode execution step (S9) to dub only the music information of the CD on the recorded video screen without the insertion of the voice message signal.

However, when the appropriate voice message signal to be recorded in the audio track of the current recording scene is selected from the various voice message signals stored in the memory means as a result of the judgment during the multi-channel voice message selection judging step S8, that is, any particular of the memory means is selected. If the channel is selected, the message combination audio dubbing execution step (S10) is performed. In this message combination audio dubbing execution step (S10), the selected voice message channel signal, for example, the video recording of the voice message of the congratulatory voice message of the voice actor is recorded. After recording in the initial audio track of the screen, the music information of the CD selected by the user is dubbed.

That is, the user selects a suitable voice message signal to be recorded in the audio track of the current recording scene from various voice message signals stored in the memory means 24 displayed on the display 20 through the voice message selection key of the key input unit 17. In this case, 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. Then, the microcomputer 2 drives the VRC deck 3, in which the voice message signal of the specific channel selected from the multi-channel voice message signals stored in the memory means 24 is mounted on the current VCR deck 3. The recording is performed for a certain time in the audio track of the video tape. For example, the recorded voice message signal can be selectively recorded with various types of voice message signals corresponding to the recording contents of the video tape, that is, a description of the user's recorded contents, a congratulatory message, or a voice message or an announcer's guide message. have.

After the multi-channel audio message signal is dubbed into the initial audio track of the video tape, the microcomputer 2 connects the audio signal input switch 19 to the CD deck 1 side so that the audio signal of the CD deck 1 is received. Switching is switched to be input to the VCR deck (3), at which time the image input switch 18 is 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.

On the other hand, after the message combining audio dubbing execution step (S10) to proceed to the user message re-input determination step (S11) to determine whether the voice message reselection key signal is input from the current user according to the recording content change. As a result of the determination during the user message re-input judging step S11, if the recorded content is not changed and a key signal for reselecting the voice message mode is not input, the process returns to the previous step S10 and repeats the loop. However, as a result of the determination during the user message re-input judging step (S11), if the recording contents are changed, for example, the recording contents of the videotape are changed from the recording contents of the current audio dubbing to another recording contents, and the user reselects the voice message mode. When the key signal is inputted, the multi-channel voice message reselection judging step (S8) is performed to determine whether a suitable voice message signal to be recorded in the audio track of the current recording scene is reselected among the various voice message signals stored in the memory means. . In the multi-channel voice message reselection determining step (S8), if the appropriate voice message signal to be recorded in the audio track of the current recording scene is not selected among the various voice message signals stored in the memory means, the message-combined audio is selected. Returning to the dubbing execution step (S10) and repeats the loop.

However, as a result of the determination during the multi-channel voice message reselection determining step (S12), if any particular channel is reselected among the various voice message signals stored in the memory means, the process proceeds to the audio message dubbing redo step (S13) and the reselected voice message channel. Signal For example, a user's graduation message message is recorded and recorded in the initial audio track of the video screen, and then dubbing music information of the CD selected by the user.

That is, when the recording contents of the video tape are changed while the audio dubbing mode is executed by inserting and executing the multi-channel voice message, and the user presses any key among the keys installed on the key input unit 17, the microcomputer 2 records the recorded contents. Recognizing the change as a key signal indicating the change is to display various voice message signals stored in the memory means 24 displayed on the display 20 through the OS unit 23. If the user reselects the voice message signal that is determined to be suitable for recording in the audio track of the current recording scene among the multi-channel voice message signals displayed on the display 20, the microcomputer 2 recognizes the reselected voice message signal. The audio message signal of a specific channel is recorded for a certain time in an audio track of a tape on which other recordings are recorded. For example, the recorded voice message signal selects and records various types of voice message signals corresponding to the recording contents of the video tape, that is, the user's graduation message.

Therefore, according to the present invention, when multiple recording contents are recorded in the same video tape, it is possible to dub various voice message signals according to the recording contents.

As described above, the present invention is to separate and store various voice message signals into multiple channels, and to select and record a voice message signal suitable for various recording contents recorded on a video tape during audio dubbing, and then perform an audio dubbing operation. According to the recording contents of the video tape, the audio dubbing with the appropriate voice message signal is performed. Therefore, the system's utility can be improved, and the system can continuously record the voice message signal and the audio dubbing suitable for the recording contents according to the user's intention. Therefore, there is an effect that the functionality of the system is significantly increased accordingly.
