Description

Operation mode color display method of composite product combining CD and VCD

The present invention relates to a method for displaying an operation mode color of a composite product combined with CD and V. In particular, when selecting a mode of a multiple operation mode in which the function setting keys of the operation panel are shared, the function setting key input confirmation signal of the selected mode is selected. By distinguishing and displaying color signals, the present invention relates to an operation mode color display method of a composite product in which a CD and a V-C are combined to improve erroneous operation due to functional operation of a plurality of operation modes.

In general, a combination product is a combination of systems having separate functions, for example, a video cassette recorder (VCR), a compact disk, or a compact (CD) that reproduces or records information recorded on a video tape. It refers to a product that combines a compact disk player (hereinafter referred to as CDP) that processes information on disk graphics.

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 control the functional operation of the CD deck 70 and A microcomputer 71 for controlling the operation collectively, a VCD deck 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 VCD deck 72 or the CD deck 70 are provided. It is provided.

One end of the microcomputer 71 is connected with a key input unit 75 for inputting a function setting key signal according to a plurality of operation modes, for example, PLAY, STOP, STILL, REW, and FF KEY. 72, one end of the CD deck 70 or an external line, such as an external TV, is connected to a video input switch 76 for inputting to a VLC deck 72 to record an image output signal. One end of the 72 is connected to a voice signal input switch 77 for inputting to a VCD deck 72 to record a voice output signal such as a CD deck 70 or an external line, such as an external TV. 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, if you look at the operation of the combination product combined with the conventional CD and V-Cal, as described above, if you first set the desired function through the function setting switch of the key input unit 75, for example, the CD (CD) In the case of playback, 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 the 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 does not operate because the switching contact is not connected.

However, if the user wants to record an external input, for example, a TV signal on the VLC tape, the microcomputer 71 recognizes this and executes the VLC 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 an 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 VLC deck 72 via the video input switch 76 and the audio signal input switch 77. Accordingly, this BC-DEC 72 records the video and audio signals of the input TV on the video tape.

However, in the conventional composite product as described above, the function setting keys of the key input unit 75, for example, PLAY, STOP, STILL, REW, and FF KEYs, are commonly used to set the functions of the VCD deck 72 and the CD deck 70. In this case, the user frequently misoperates, thereby degrading the functionality of the system. Also, since the function setting keys of the key input unit 75 are used without any distinction depending on the operation mode, the user sets their own functions. Therefore, there is a problem that the use of the system is quite uncomfortable accordingly.

Therefore, the present invention has been invented to solve the above-mentioned problems, and when the mode selection of the multi-operation mode in which the function setting key of the operation panel is shared, to display the function setting key input confirmation signal of the selected mode by color signal. Therefore, the misoperation caused by the function operation of the multi-operation mode is prevented, and thus the purpose of providing a method for displaying the operation mode color of the composite product combined with CD and V-C is to improve the functionality of the system.

Still another object of the present invention is that when the user uses the function setting key of the operation panel of the multi-operation mode, the user clearly confirms the set function by the color signal through the display unit, thereby increasing the reliability of the system. The present invention provides a method of displaying the operation mode color of a product.

In order to achieve the above object, the present invention provides a mode signal determination step of determining whether the current V mode is set in a combination product of CD and V-CAL, and the result of the decision of the mode of the mode signal determination. Is set, the system operation mode is changed to V-Cal mode, and the V-Cal operation mode function execution step for executing the recording or playback function of the set video tape and the V-Ral operation mode function execution step are executed. According to the VLC operation mode color display execution step of confirming that the VCD operation mode is executed and outputting a color lamp signal distinct from the color signal according to the CD operation mode, and the judgment result during the mode signal determination step. If VCD mode is not set, the system switches to CD mode. After the CD operation mode function execution step for executing the specified CD playback function, and after the CD operation mode function execution step, it is confirmed that the CD operation mode is executed according to the user's function setting signal. And a CD operation mode color display execution step of outputting a color lamp signal distinguished from the outside.

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

In addition, an operation panel unit 17 for inputting a function setting signal of a plurality of operation modes is connected to one end of the microcomputer 2, and one end of the CD deck 3 or an external line is connected to one end of the VCD deck 3. In order to record the video output signal of the video input switch 18 which is connected to the BC R Deck (3) is connected, the audio output signal of the CD deck (1) or an external line at one end of the BC R Deck (3) The audio signal input switch 19 for inputting the VLC deck 3 is recorded. A display 20 is connected to an output terminal of the image output selection switch 4, a speaker 21 is connected to the audio output selection switch 5, and a plurality of operations are performed at one end of the microcomputer 2. The L CD display unit 22 for displaying the display signal according to the function setting of the mode as a color signal is connected. In addition, a tuner circuit 23 for receiving a TV broadcast signal and demodulating and amplifying a signal is connected to an input terminal 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, the method of the present invention applied to the composite product having the above configuration will be described.

In the method of the present invention, first, as shown in FIG. 4, the process proceeds from the initial state S1 to the mode signal determination step S2 to determine whether the present VR mode is set. As a result of the determination during the mode signal determination step S2, if the BC mode is set, the process proceeds to the recording function setting determination step S3, and it is determined whether the recording function is set in the BC AL deck. When the recording function is not set in the BC RDK as a result of the determination in the recording function setting determination step S3, the process proceeds to the execution of the BC R playing function (S4) to execute the set V playing function. However, if it is determined during the recording function setting determination step (S3) that the recording function is set to BC RDK, the process proceeds to the execution of the BC recording function (S5) and executes the set BC recording function.

After the VRC recording function execution step (S5) and the VRL playback function execution step (S4), the VRC operation mode color display execution step (S6) is carried out according to the function setting signal of the current user. A color lamp signal for confirming that it is being executed, for example, a red lamp signal (RED LAMP SIGNAL) which is distinguished from the color signal according to the CD operation mode, is output through the LCD display unit.

That is, when the recording function setting signal for loading the video tape on the BC Aldek 3 and recording the set information, for example, the broadcast signal, is set through the operation panel unit 17, the microcomputer 2 switches the image input switch. (18) and the audio signal input switch 19 are switched to the tuner section 23. At this time, since the current system is operating in V-CD mode, the CD deck 1 does not operate. Accordingly, the video signal and the audio signal of the broadcast signal tuned by the tuner unit 23 are input to the BC Aldek 3 through the video input switch 18 and the audio signal input switch 19. Then, the BC RD 3 records the broadcast signal of the tuner unit 23 input through the video input switch 18 and the audio signal input switch 19 on the video tape.

Further, at the same time as the VCD operation mode is executed, the microcomputer 2 drives the L CD display unit 22 to confirm that the current system is operating in the VCD mode. For example, the color signal according to the CD operation mode and The red lamp signal (RED LAMP SIGNAL) is to be output through the LCD display 22. Accordingly, the user can easily recognize that the system is currently operating in the V-Cal mode by checking the color lamp signal displayed through the L CD display unit 22.

On the other hand, if it is determined during the mode signal determination step S2 that if the CD mode is not set, the system is set to the CD mode, so the process proceeds to the VCD function setting determination step S7 and the current system is the CD mode of the CD mode. It will determine if the function is set. If the VCD function setting determination step (S7) determines that the VCD function is not set, the process proceeds to the normal CD execution step (S8) to reproduce the general CD and output it to the outside. However, when the decision on the VCD function setting determination step (S7) indicates that the VCD function is set, the VCD function execution step (S9) is performed to reproduce the VCD currently mounted on the CD deck and output it to the outside. do.

After the normal CD execution step (S8) and the VCD function execution step (S9), the operation proceeds to the CD operation mode color display execution step (S10) and confirms that the CD operation mode is executed according to the current user function setting signal. The color lamp signal, for example, a blue lamp signal (BLUE LAMP SIGNAL) which is distinguished from the color signal according to the VR operation mode is output through the LCD display.

That is, when the user mounts the disc 6 of the VCD on the tray and the CD mode, especially the VCD function, is set in the system, the microcomputer 2 recognizes this and drives the CD deck 1. Therefore, the microcomputer 2 switches the image output selection switch 4 and the audio output selection switch 5 to the CD deck 1 side. In addition, the microcomputer 2 drives the spindle motor 14 through the servo control unit 15 so that the disk 6 rotates. 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 amplifier 8 amplifies the input detection data signal to a predetermined level and then inputs it to the digital signal processor 9. In addition, the digital signal processing unit 9 inputs the digital signal of the inputted VCD to digital signal processing, for example, FM M demodulation and error correction, and then inputs it to the microcomputer 2. Then, the microcomputer 2 determines 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 PSC region at the $ A0 position of the POINT region of the thio sea stored in the TOS RAM is $ 20.

If the PS area is $ 00, the CD, or if the CD-ROM is $ 10 CD-I, if $ 20 is the CD-ROM (VCD).

Therefore, when the PS area is $ 20, it is determined as VCD, and the disc track information contained in the TOS of the disc 6 is read and stored in order. That is, the contents of ENTRIES VCD, LOT, VCD, PSD, VCD track 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, and accordingly, the MPEG video / audio decoder 11 inputs 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. The audio data signal input to the audio signal processor 13 is low frequency amplified and then output to the outside through the speaker 21 via the audio output selector switch 5. The video signal is processed by 12) and then synchronized with the audio signal and displayed via the display 20 as an image signal via the video output selection switch 4.

Further, at the same time as the CD operation mode is executed, the microcomputer 2 drives the L CD display unit 22 to confirm that the system is currently operating in the CD mode, for example, unlike the color signal according to the VCD operation mode. The distinctive blue lamp signal (BLUE LAMP SIGNAL) is output through the LCD display unit 22. Accordingly, the user can easily recognize that the system is operating in the CD mode by checking the color lamp signal displayed through the LCD display unit 22.

As described above, according to the present invention, the function setting key input confirmation signal of the selected mode is displayed as a color signal when selecting a mode of the multiple operation mode in which the function setting keys of the operation panel are shared. This prevents misoperation and improves the functionality of the system. In addition, when the user uses the function setting keys on the operation panel of the multi-operation mode, the user clearly confirms the function set by the color signal through the display, thereby increasing the reliability of the system. have.
