How to execute multiple functions of combined product with CD and VRF

The present invention relates to a method of executing multiple functions of a combination product of CD and VCD. In particular, the present invention relates to a method of executing a multiple function of a composite product. By regenerating the CD, it is possible to simultaneously execute a plurality of operation modes in a system, and accordingly, the present invention relates to a method of executing a multiple function of a combination product of CDs and VCDs, which improves the functionality of the system.

In general, a combination product is a combination of systems having separate functions, for example, a video cassette recorder and a compact disk or CD that reproduce or record information recorded on a video tape. (Compact disk graphics) A product that combines a compact disk player (hereinafter referred to as CDP) that processes information.

Then, one embodiment of such a composite product with reference to Figure 1, the CD deck (70) for reproducing the information contained in the CD or CD disc, and the control operation of the CD deck 70 and the system of A microcomputer 71 for controlling the operation as a whole, a VCD deck 72 for reproducing or recording information recorded on the videotape according to the operation control signal of the microcomputer 71, and the VCD deck 72 An image output selection switch 73 for selectively outputting only the video information signal of the CD deck 70 and an audio output selection switch 74 for selectively outputting only the audio signal of the V Deck 72 or the CD deck 70 are provided. It is provided.

In addition, one end of the microcomputer 71 is connected to a key input unit 75 for inputting a user's function setting signal, and one end of the V-deck 72 is connected to a CD deck 70 or an external line. In order to record an image output signal of a TV or the like, an image input switch 76 is connected to the VCD deck 72, and one end of the VCD deck 72 is connected to the CD deck 70 or an external line. In order to record an audio output signal of an external TV or the like, a voice signal input switch 77 for inputting to the VDLC deck 72 is connected.

A display 78 is connected to an output terminal of the image output selection switch 73, and a speaker 79 is connected to the audio output selection switch 74.

On the other hand, when looking at the operation of the combined product combined with the conventional CD and VCD, first, if you set the desired function through the function setting switch of the key input unit 75, for example, to play the CD In this case, when the CD is mounted on the CD deck 70 and the CD playback switch of the key input unit 75 is set, the microcomputer 71 recognizes this and sets the CD playback function.

That is, the microcomputer 71 inputs the switching control signal to the CD deck 70 according to the CD regeneration function setting signal of the key input unit 76. At the same time, a switching control signal is also input to the video output selection switch 77 and the audio output selection switch 78 to connect all switching contacts of the output terminal to the CD deck 70 side.

Then, the CD deck 70 is driven to reproduce the information contained in the CD so that the video signal is displayed on the display 79 via the video output selection switch 77. In addition, the voice signal is emitted to the speaker 80 via the voice output selection switch 78.

At this time, other decks other than the CD deck 70, that is, VCD deck 72 is not operating because the switching contact is not connected.

By the way, if the external input during the operation, for example, if you want to record the TV signal on the V-Ral tape is set via the key input unit 75, the microcomputer 71 recognizes this and executes the V-Ral external recording function.

That is, the microcomputer 71 drives the VLC deck 72 and simultaneously switches the image input switch 76 to be connected to the external input terminal. At the same time, the voice output switch 77 is also switched to the external input terminal.

Then, the video and audio signals of the external TV are input to the VCD deck 72 via the video input switch 76 and the audio signal input switch 77. Therefore, this V deck 72 records the video and audio signals of the input TV on the video tape.

However, since the conventional composite product as described above does not have a plurality of operation functions, for example, during the recording function of the VRC deck 72, the information signal of another deck or an external input cannot be used. It was necessary to wait unnecessarily until the recording function of 72) was terminated, and another deck could not be operated while the recording function of the VCD deck 72 was executed.

Therefore, the present invention has been invented to solve the above problems, and is provided with a plurality of operation modes to simultaneously perform other operation modes while the recording function mode of the videotape is used to receive broadcast signals or play VCDs. By doing so, since a plurality of operation modes can be simultaneously executed in one system, the object of the present invention is to provide a multi-function execution method of a combination product of CDP and V-C that improves the functionality of the system.

Another object of the present invention is to obtain information that matches the user's preferences using other modes without the user having to wait unnecessarily until the recording function of the videotape is completed. It is to provide a method of performing a multi-function of a combination of V-Cal combined products.

In order to achieve the above object, the present invention executes a V-recording function for executing a set V-recording function when a recording function is set on a VCD deck in a VCD mode in a combination product of CD and VLC. And a multi-operation mode setting determination step of judging whether a setting signal for executing a plurality of other functions while executing the recording function of the V-RC deck is input to the current system after the execution of this V-recording function. If the multi-operation mode setting signal is input as a result of the determination during the setting determination step, the multi-operation CD mode determination step for determining whether the multi-operation CD mode is currently set in the system and the multi-operation CD mode determination step If the CD mode is not set, the recording function is performed with VCD Deck. In the case of executing the external input function which outputs the external video signal or the audio signal input from the external line through the display and the speaker, and the VCD function of the multi operation CD mode is determined as a result of the determination during the multi operation CD mode determination step. While playing the recording function of the VCD deck is characterized by consisting of the VCD function execution step of playing the VCD currently mounted on the CD deck to output to the outside.

It is connected to one end of the digital signal processing unit 9 and the servo control unit 15 for controlling the driving operation of the motor 14 and switched by a switching control signal of the microcomputer 2 to be input from the digital signal processing unit 9. And a decoder decoder 16 for graphically decoding the subcode data.

Here, the video signal processing unit 12 is connected to the input terminal of the video output selection switch 4, and the audio signal processing unit 13 is connected to the input terminal of the audio output selection switch 5.

In addition, one end of the microcomputer 2 is connected with a key input unit 17 for inputting a function setting signal of the user, and one end of the V-deck 3 outputs an image of the CD deck 1 or an external line. An image input switch 18 for inputting the signal to the DVD deck 3 for recording a signal is connected, and the audio output signal of the CD deck 1 or an external line is recorded at one end of the BC deck 3. The audio signal input switch 19 for inputting to the VCD deck 3 is connected.

A display 20 is connected to an output terminal of the video output selection switch 4, and a speaker 21 is connected to the audio output selection switch 5. In addition, a tuner circuit 22 for receiving a TV broadcast signal and demodulating and amplifying a signal is connected to the input terminals of the video output selection switch 4 and the audio output selection switch 5, respectively.

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 will be described the method of the present invention applied to the composite product configured as described above.

The method of the present invention first proceeds to the mode signal determination step S2 in the initial state S1 as shown in FIG. 4 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.

However, if it is determined during the mode signal determination step (S2) that if the VRC mode is set, it proceeds to the recording function setting determination step (S4) it is determined whether the recording function is set to the VRC deck. When the recording function is not set on the VCD deck as a result of the determination in the recording function setting determination step (S4), the process proceeds to the execution of the VRC playback function (S5) and executes the set VRL playback function.

However, if the recording function is determined in the recording function setting determination step (S4), and if the recording function is set in the VRC deck, the control proceeds to the execution of the BC recording function (S6) to execute the set VRC recording function.

In other words, the video deck is loaded on the VRC deck 3 and recorded information is recorded, for example, a TV broadcast signal, etc. At this time, the microcomputer 2 switches the image input switch 18 and the audio signal input switch 19 to the tuner unit ( 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 deck 3 through the video input switch 18 and the audio signal input switch 19. This V deck 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 videotape.

On the other hand, after the VRC recording function execution step (S6) to proceed to the multi-operation mode setting determination step (S7) and the setting signal to execute the other functions while executing the multi-operation mode, that is, the VCD deck recording function in the current system It is determined whether it is entered.

As a result of the determination during the multi-operation mode setting determination step S7, if the multi-operation mode setting signal is not set, the process returns to the previous step S6 to repeat the loop.

However, if it is determined during the multi-operation mode setting determination step (S7), if the multi-operation mode setting signal is input, the process proceeds to the multi-operation CD mode determination step (S8) to determine whether the multi-operation CD mode is currently set in the system. Done. When the multi-operation CD mode is determined in step S8, if the multi-operation CD mode is not set, the control unit proceeds to the external input function execution step (S9) and executes the recording function with the VRC deck to input from the external line. The external video signal or audio signal is output through the display and the speaker.

In addition, if it is determined during the multi-operation CD mode determination step S8, if the multi-operation CD mode is set, the VCD function determination step S10 is performed to determine whether the current VCD function is set. If the VCD function is not set, when the VCD function is not set, the control returns to the CD mode execution step (S3) and executes the recording function of the VCD deck to play the normal CD to externally. Will output

However, as a result of the determination on the VCD function determination step (S10), if the VCD function is set, the process proceeds to the VCD function execution step (S11) to execute the recording function of the VCD deck and is currently mounted on the CD deck. The VCD will be played and output to the outside.

After the VCD function execution step S11, the VCD recording function end determination step S12 is performed to determine whether the current VCD recording function is terminated.

In addition, if it is determined during the termination of the VR recording function termination step (S12), if the BC recording function is not terminated, the operation returns to the recording function execution step (S6) to repeat the loop. However, if it is determined during the termination of the BCD recording function (S12), if the BCD recording function is ended, the process proceeds to the end step.

That is, when the multi-function CD mode, in particular, the VCD function is set while the recording function is executed on the VCD deck 3, the microcomputer 2 recognizes this and executes the recording function set by the VCD deck 3 and executes the recording function. At the same time, the CD deck 1 reproduces the VCD signal and outputs it to the outside. At this time, the video output selection switch 4 and the audio output selection switch 5 are switched to the CD deck 1 side.

Therefore, when the user mounts the disk of VCD on the tray while the recording function of the VCD deck 3 is executed, the microcomputer 2 drives the spindle motor 14 through the servo control unit 15, Accordingly, the disk 6 is rotated. 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. The RF amplification section 8 amplifies the input detection data signal by a predetermined level and then inputs the detected signal to the digital signal processing section 9.

In addition, the digital signal processing unit 9 inputs the digital signal of the inputted VCD into the digital signal processing, 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.

At this time, as shown in FIG. 3, the microcomputer 2 determines whether or not the PSEC area at the $ A0 position of the point area of the thio city stored in the TOS RAM is $ 20.

Wherein the PSEC area is $ 00, the CDDA or CD-ROM, $ 10 is the CD-I, and $ 20 is the CD-ROM XA (VCD).

Therefore, if the PSEC area is $ 20, it is judged as VCD, and the disc track information contained in the TOS of the disc 6 is read and stored in order. Ie ENTRIES. The contents of the VCD, LOT.VCD, and PSD.VCD tracks are read sequentially and stored in TOSRAM. Then, the microcomputer 2 inputs the data control signal of the VCD to the MPEG video / audio decoder 11 so that 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.

Then, the audio data signal inputted 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 transmitted to the video signal processor ( 12 is processed as a video signal and then displayed as an image signal through the display 20 via the video output selection switch 4 in synchronization with the audio signal.

Thus, the user can view the video of the VCD on the display 20 while recording the video tape on the VCD deck 3.

As described above, the present invention includes a plurality of operation modes, and simultaneously executes other operation modes while the recording function mode of the videotape is executed to receive broadcast signals or play VCDs, thereby enabling a plurality of operation modes in one system. The system can be run at the same time, which improves the functionality of the system and enables users to obtain information that matches their preferences using other modes without the user having to wait unnecessarily until the recording function of the videotape is completed. It also has the effect of increasing the convenience of.
