How to dub audio for a multi-device

The present invention relates to a multifunctional product equipped with a compact disc player and a VSI in one set. In particular, in a video-CD composite device, the songs recorded on each track of the CD can be sorted in a desired order and dubbed to an audio track of a video tape. An audio reservation dubbing method of a multi-device is possible.

The following describes the operation process of the compact disc player part of a video-CD composite product.

First, when the compact disc control signal input from the key input unit is input to the microcomputer, the microcomputer outputs the motor control signal to the driver side. Accordingly, the drive motor for rotating the turntable on which the compact disc is placed is rotated by the driver.

In this way, the compact disc is rotated and the audio digital signal of each track detected by the pickup device is applied to the focus and tracking controller via an amplifier. The focus and tracking controller provides position control information to the actuator side that determines and controls the position of the pickup device based on the input digital signal, and transmits the read digital audio signal to the micom side.

The microcomputer outputs the digital reproduction signal on the input compact disc to the digital signal processor. The digital sound signal processed by this digital signal processor is input to a digital analog converter, where the digital audio signal is converted into an analog audio signal and output.

The analog sound signal output from the digital to analog converter is amplified through an output amplifier and output to the speaker.

Unlike compact discs that reproduce and output audio signals in this way, VSIal can record signals from television channels or external input video signals on video tapes, and can play back these tapes or pro tapes. You can dub audio onto a videotape with the playback output of the audio source.

This audio dubbing can be easily performed by using the simple editing function provided in the multi-function device.

However, if you want to dub other audio on the audio track of a video tape recorded by VSI in a video-CD composite device, for example, playback audio of a CD, you can simultaneously play the audio dubbing mode of VSI and the audio playback mode of the CD. Since the choice has to be made, the problem is that the operability is very complicated.

SUMMARY OF THE INVENTION An object of the present invention is to provide a compact disc player and a composite device equipped with one VSI in one set, and to perform dubbing of the tracks on each track of the CD in a desired order to dub the audio tracks of a video tape. An audio reservation dubbing method is provided.

The present invention provides a key input unit, a VSI microcomputer for processing and transmitting CD reservation playback data input through the key input unit, and a CD memory for storing sequential reserved playback track data input to the CD micom; And a recording unit configured to dub a CD sound sequentially reproduced from a CD playback unit on an audio track of a video tape on which a video signal is recorded according to the control of the BT microcomputer. And selecting and registering the desired playback sequence of the desired track by using the CD reservation function. If there is an audio dubbing key input, the VSI unit is switched to the video tape audio dubbing mode and the reservation sequence is performed. Playing the cd track according to the When the sequential playback of the audio rack audio dubbing is completed in the reserve comprises stop audio dubbing and exits.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

1 is a circuit diagram of a compact disc player including a reservation automatic audio dubbing function for implementing the present invention, and a VSI-CD composite apparatus incorporating a BCIAL function.

As referred to herein, the key input signal generated from the key input unit 11 for selecting and controlling the function of the VSI and the function of the CD is the VMI microcomputer 10 having the servo unit 12 and the memory 14. It is configured to be applied to the side.

The output of the tuner 13 in which the television broadcast channel is tuned according to the VMS microcomputing control is inputted to the recording unit 15 of VSI, and when there is a selection of the VISA recording function, it is displayed on the video tape. Configure to be recorded.

In addition, the reserved reproduction program data of the CD inputted to the VMI microcomputer 10 through the key input unit 11 is transmitted to the CD memory 17 via the CD microcomputer 16 and stored.

The CD microcomputer 16 includes a servo unit 18 and a reproducing unit 19 for sequentially reproducing tracks of the disc in key input or reservation order, and reproduces audio of a compact disc reproduced by the reproducing unit 19. The output is configured to be transmitted to the recording unit 15 under the control of the microcomputer and provided as a source for audio dubbing.

The VMI microcom 10 and the CD microcom 16, which are data-linked for mutual data exchange, read data stored in their memories 14 and 17 according to the on-screen display command by the key input unit, respectively. ) To be output to the monitor 21 or the television screen.

The reservation dubbing operation of the present invention will be described in detail based on the composite device circuit configured as described above.

First, when the CD function is selected through the key input unit 11 of the video-CD composite product, the key input signal is applied to the CD micom 17 of the CD unit through the VMI microcomputer 10 so that power is supplied to the CD unit. Thereafter, when the user of the multi-component device mounts the CD on the CD tray and selects a play key, the CD microcomputer 16 controls the CD playback unit 19 and the servo unit 18 so that the information recorded on the disk is reproduced and output. do.

This playback output can be instantly dubbed onto a videotape through the simple editing functions typically found in composite equipment. In addition, when the desired track is sequentially designated and reserved among the recordings recorded on the disc by the CD microcomputer 16 through the key input unit 11, such data is stored in the CD memory 17, and then the track sequence designated according to the play key input. It is reproduced sequentially based on.

On the contrary, if the VSI unit is selected through the key input unit 11, the VMI microcom 10 cuts off the data transmission system to the CD micom 16 and the servo unit 12, the recording unit 15, and the tuner. (13) to control recording or scheduled recording or playback of video tape or audio dubbing or television broadcast program in any one mode selected from among reception modes.

When the audio continuous dubbing mode is selected through the CD reservation via the key input unit 11 of the VSI-CD composite device, the CD micom 16 data-linked to the MICOM 10 is selected. The playback is controlled in the order of the tracks stored in the memory 17, and the VMS microcommunication unit 12 and the block 15 are controlled to execute the audio dubbing mode.

Through this process, the continuous audio dubbing operation using the reservation track sequential playback of the CD is performed according to the flowchart of FIG. 2.

As referred to herein, after the power of the multifunction device is turned on, the step of selecting the CD mode through the key input unit is performed.

Following the above steps, the step of designating and reserving the desired playback order of the desired tracks using the CD reservation function is performed. If there is an audio dubbing key input, the VSI unit is switched to the video tape audio dubbing mode, and the CD track is set according to the reservation order. The audio dubbing operation is performed through the step of reproducing.

Following the above steps, when audio sequence playback of the reserved track ends, audio dubbing is interrupted and terminated, thereby finally completing dubbing of the CD playback audio signal on the audio track of the videotape.

As a result, it is possible to reserve dubbed audio in a desired CD track order continuously for a desired time.

As described above, the present invention provides a method in which CD tracks are reserved in a desired order when audio dubbing is performed using a video-CD composite product equipped with a compact disc player and a VSI device in one set. Audio dubbing will automatically produce a unique effect that can be continuously rinsed.
