By the way, in such a composite apparatus of optical disc player V.C.R, at the time of simultaneous (SYNC) recording in which the contents recorded on the optical disc are recorded on the cassette tape (in this case, the optical disc unit is in playback mode V.C.Al. In this case, only video and audio data recorded on the optical disc can be recorded without recording TOC (table of content) information indicating the information of the data recorded on the optical disc and time information recorded on the track. Therefore, when recording the data recorded on the optical disc on the cassette tape and then attempting to execute various functions such as playback on V.C.R, there is a problem that there is a problem in that there is no content information on the recorded data. .

Accordingly, the present invention has been proposed to solve such a problem in the related art, and an object of the present invention is to provide a cassette tape for recording contents recorded on an optical disc in a composite device of an optical disc player and V.C.R. It also records the TOC information recorded on the optical disc and the time information recorded on the track, so that it is convenient when you want to execute the functions such as replaying and searching the recorded contents in V.C.R. It is to provide a synchronous recording method in the composite device of player and V.C.R.

According to a preferred embodiment of the present invention for achieving the above object, the optical disc player and the video cassette recorder are organically coupled to each other, and the optical disc player and the video cassette recorder are composed of the optical disc player and the video cassette recorder. When synchronizing recording of data recorded on the disc onto the cassette tape in the video cassette recorder section, the optical disc player and the video cassette recorder which record the TOC information recorded in the TOC area of the optical disc and the time information recorded on the track together. In the synchronous recording method in a composite device, (A) determining whether the synchronous recording signal if the key signal is input, and (B) if the key signal input in the step (A) is a synchronous recording signal, the optical disk Section is set to playback mode and the video cassette recorder section is recording Reads the TOC information recorded on the optical disk after the setting, and writes the data on the cassette tape after OSD (on screen display) processing; Recording the video and audio data, and recording the time information together by OSD processing; and (d) determining whether the synchronous recording is completed and, when completed, setting the optical disc unit and the video cassette recorder unit to a standby mode and recording. Stopping the step.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a block diagram of an optical disc player and V.C. composite device for implementing the present invention. As shown in Fig. 1, the optical disc player and V.C. composite for implementing the present invention are shown. The apparatus includes an optical disk unit including an optical pickup unit 110, an RF (raido frequency) amplifier 120, a digital signal processor 130, a microcomputer 140, a servo controller 150, and a spindle motor 160. 100, an audio signal processor 210, an audio head 220, a video signal processor 230, an OSD (on screen display) processor 240, a video head 260, and a screen 250. It consists of the C. Albu 200. On the other hand, the microcomputer 140 controls not only the optical disk unit 100 but also the V. C. egg unit 200 at the same time.

First, the optical pickup unit 110 in the optical disk unit 100 performs the optical pickup and outputs the RF signal read accordingly. The spindle motor 160 is driven according to the servo signal of the servo controller 150 to rotate the disk D so that the data recorded on the optical disk D is read by the optical pickup unit 110.

In addition, the RF signal amplification unit 120 amplifies the RF signal provided from the optical pickup unit 110 and provides it to the digital signal processing unit 130.

The digital signal processor 130 outputs the amplified RF signal provided from the RF amplifier 120 to the audio decoder 170 and the video decoder 180 by digital signal processing and error correction. The servo signal is output to the servo controller 150. The servo controller 150 processes the servo signal provided from the digital signal processor 130 and provides the servo signal to the optical pickup 110 and the spindle motor 160 so that the focus servo and the tracking servo can be performed.

Meanwhile, the audio decoder 170 and the video decoder 180 detect and decode audio and video data from the signal provided from the digital signal processor 130, respectively, and then the audio signal processor 210 of the V. C. 200 unit 200. And the video signal processor 230.

In addition, the V. C. unit 200 reproduces the video and audio signals recorded on the cassette tape and also records the audio and video signals provided through the optical disc unit 100 or an external input terminal (not shown). .

That is, the audio signal processor 210 and the video signal processor 230 process audio and video signals from the decoded audio and video signals provided from the audio decoder 170 and the video decoder 180, respectively. Output to the OSD processing unit 240.

Accordingly, the audio head 220 records the audio signal provided from the audio signal processor 210 on the audio track of the cassette tape. In addition, the OSD processor 240 OSD-processes the video signal provided from the video signal processor 240 to the screen 250 and / or the video head 260. When the OSD processing is not performed, the OSD is bypassed. (bypass)

Meanwhile, according to the present invention, when a synchronous recording signal is input through a key input unit (not shown) which may be a key matrix or a remote controller, the microcomputer 140 generates a control signal so that the optical disc unit 100 is in a playback mode. V. C. Al part 200 is set to the recording mode.

Typically, when the optical disc D is mounted in a disc tray (not shown), the TOC information recorded in the lead-in area is read from the disc and the internal memory of the microcomputer 140 (not shown). Are stored in.

Therefore, in the present invention, when synchronous recording is started, the microcomputer 140 first processes the TOC information recorded on the optical disk D to be provided to the V.C.albu 200. The TOC data is stored in the internal memory. On the other hand, the TOC information stored in the memory is read out and output. When the TOC information is not stored, a control signal is generated to read the TOC information on the optical disc D.

That is, at the beginning of synchronous recording, the microcomputer 140 outputs TOC information to the OSD processing unit 240 of the V. C. 240 unit, and the OSD processing unit 240 processes the TOC information provided from the microcomputer 140 by text processing. To the video head 260 to be recorded on the cassette tape via the video head 260. In addition, the O.S.D processed T.O.C information may be displayed as text through the screen 250.

When the recording of the TOC information is completed through this process, the microcomputer 140 generates a control signal so that the actual video and audio data can be reproduced and recorded.

That is, the reproduction data picked up through the optical pickup unit 110 on the disc D may be configured as described above with respect to the RF amplifier 120, the digital signal processor 130, the audio decoder 170, or the video decoder 180. After processing through the audio signal processing unit 210 and the video signal processing unit 230 of the V. C. Al unit 200 is recorded on the cassette tape through the audio head 220 or the video head 260.

In addition, during such synchronous recording, the microcomputer 140 reads time information recorded on the data track of the disc D, such as video and audio data, and provides it to the O.S.D processing unit 240. This time information is then processed by the O.S.D processing unit 240 and recorded on the cassette tape along with the video data via the video head. Accordingly, TOC information and time information recorded together with the video signal are displayed together with the video signal through the screen 250 at the time of reproduction.

That is, when synchronous recording is performed to reproduce data of an optical disk recorded on a cassette tape, the characters for each image and time information for the image are always displayed together.

In step S10, it is determined whether a key signal for executing a predetermined function is input. When the key signal is input in step S10, in step S20, it is determined whether the input key signal is a key signal for synchronous recording. do.

If the key signal input in step S20 is not a key signal for synchronous recording, flow proceeds to step S60 to execute a function corresponding to the input key signal, and then the flow ends, and the input key signal performs synchronous recording. If it is a key signal, the process proceeds to step S30.

When the process proceeds from step S20 to step S30, in step S30, the optical disc unit 100 is set to the playback mode and the V. C. AL unit 200 is set to the recording mode, and the TOC recorded on the optical disc is recorded. After reading the information, the OSD is processed and recorded on the cassette tape.

Thereafter, when step S30 is completed, in step S40, video and audio data recorded on the optical disc are read out and recorded on the cassette tape, and corresponding time information is recorded by O.S.D processing. In steps S30 and S40, the TOC information and time information may be recorded on the cassette tape while being displayed on the screen 250. FIG.

Further, in step S50, it is determined whether synchronous recording is completed. If it is determined in step S50 that synchronous recording is completed, the optical disk unit 100 and the V. C. 200 unit are set to the standby mode. And end the flow.

Therefore, according to the present invention, when it is desired to execute a function such as playback on data of an optical disk recorded on a cassette tape after synchronous recording, TOC information is displayed as a character at the beginning of playback, and a time when a video signal is displayed. Since the information is displayed at the same time, it is easy to know the current playback position through the TOC data and the time information, and there is an advantage that the functions such as image search can be easily performed by using the information.
