Audio editing dubbing method of composite product

The present invention relates to a method for dubbing audio editing of a composite product. In particular, in a composite product combined with a CD and a VCD, the audio sound output from the CD can be designated according to a user's taste, and the recording sequence can be displayed on the output screen of the VR. The present invention relates to a method for dubbing audio editing of a composite product in which a background music can be inserted.

In general, a combination product of VRF and CDP has a function to classify digital signals inferred from CDP's optical pickup device into sound signals and graphic signals and directly record and record the classified signals on magnetic recording media. It is provided to.

Then, referring to FIG. 1, the structure of the above-described conventional composite product is described with reference to FIG. 1, which includes an optical pickup unit 70 for reading out a recording signal recorded on a compact disc using a laser beam. The digital signal processor 71 demodulates the waveform of the data read by the unit 70 and demodulates it into a digital signal. The digital signal processor 71 detects an audio signal and converts it into an analog signal. De-transformer 72, an acoustic signal demodulator 73 for detecting only the acoustic signal through the low pass filter of the signal output from the de-transformer 72, and a graphic of the signals digitized by the digital signal processor 71. Graphic signal demodulator 74 for detecting only a signal, and an AV switch for switching whether the signal output from the graphic signal demodulator 74 and the acoustic signal demodulator 73 outputs internally or externally. No. comprises a switching unit (75).

In addition, the AV signal is applied to the signal switching unit 75 so as to determine the input and output of the sound signal and the graphic signal, and according to the control signal of the micom 76 and the microcomputer 76 for overall control of the following functions; When the AV is connected so that the signal switching unit 75 is switched inside, the video signal processing unit 77 performs signal processing so that the incoming video signal can be recorded on the magnetic recording medium. It is connected to an audio signal processor 78 for processing a signal by modulating with a record bias so as to record the incoming sound signal according to the internal switching, and is connected to the output terminal of the video signal processor 77 and the audio signal processor 78, It consists of an Alphead unit 79 for storing and reproducing a signal on a magnetic recording medium.

In addition, the AV signal switching unit 75 is connected to an external terminal 80 for inputting and outputting signals to the outside, and a key panel 81 for applying a control signal from a user to an input port of the microcomputer 76. The audio head unit 79 includes an audio head 82 for recording and reproducing an audio signal, and a video head 83 for recording and reproducing a video signal.

Meanwhile, the audio dubbing operation of the conventional composite product having the above configuration will be described.

First, when the CD dubbing function is selected by the user through the key panel 81, the data stored in the compact disc is read at a predetermined frequency by the laser beam through the optical pickup unit 70, which is a digital signal processor. Digitized waveforms are processed via 71. The digitized data is classified into sound data and graphic data, and at this time, the classified digital sound data is converted into a linear analog signal through a die conversion unit 72. In addition, the analog signal is extracted through the audio signal demodulator 73 to detect only the audible frequency after the high frequency component is removed, and the image digital data output from the digital signal processor 71 is a graphic signal demodulator 74. The video signal is extracted through the < RTI ID = 0.0 >

The audio signal and the video signal are introduced into the signal switching unit 75. At this time, the AV signal switching unit 75 is switched to the internal switching connection by the user's audio dubbing function selection. The audio signal and the video signal introduced into the signal switching unit 75 are connected to the audio signal processing unit 78 and the video signal processing unit 77, respectively. Then, the video signal processor 77 modulates an already introduced video signal and an oscillation frequency for recording, and then transmits the signal to the RF head unit 79.

In addition, when audio dubbing is performed using a function as described above, the AV signal switching unit 75 outputs the audio data received from the optical pickup unit 70 to the audio signal processing unit 78 and the video. The video signal read from the head 83 is switched to be reproduced through the external terminal 80. Thus, background music can be inserted to match the video screen being played.

However, when dubbing background music from CD to VCD, it is necessary to record the CD's notes based on the order of the songs already recorded. After selecting the sound of the CD to be recorded again, there is a problem that it is very inconvenient to insert the background music desired by the user.

Accordingly, the present invention has been made to solve the above problems, the TOC data recorded on the CD to be output through the OS to specify the order of the songs from the user, at the same time based on the order of the specified song It is an object of the present invention to provide an audio editing dubbing method of a composite product which increases the ease of use by allowing audio dubbing to be performed.

On the other hand, the present invention for achieving the above object, the OSD output process of outputting the thio CD data of the CD in the audio editing dubbing mode, and inputs the order of the songs in accordance with the user's intention in this OSD output process And a dubbing step of dubbing the songs in accordance with the recording order of the data storing step.
