Description

Combination system for controlling output of replay-signal using OSD

The present invention relates to a combination system in which two or more different devices are connected in one system. More specifically, the present invention relates to a DVDP which connects a DVDP and a VCR into one system to control an output according to the type of each signal reproduced from the DVDP. / VCR combination system.

Two or more different devices connected to one integrated system are called a "combination system" or a "combo-system", which is abbreviated as "combo". An example of a combo system is a DVDP / VCR combo system developed to perform a combination of a digital video or versatile disk player (DVDP) and a video cassette recorder (VCR).

FIG. 1 is a diagram schematically illustrating such a DVDP / VCR combo system and peripheral devices connected thereto. The DVDP / VCR combo system 10 includes a VCR unit 11 that performs functions of a general VCR such as a function of reproducing video and audio data recorded on magnetic tape and a function of recording an externally received signal on magnetic tape. And a DVDP unit 12 which performs a function of a general DVDP such as a function of reproducing video and sound data recorded on a digital video disk (DVD). In addition to the independent functions of the VCR unit 11 and the DVDP unit 12, the DVDP / VCR combo system 10 records the images and sounds reproduced by the DVDP unit 12 on the magnetic tape in the VCR unit 11; It has the advantage of being able to perform the same complex function.

The VCR unit 11 and the DVDP unit 12 in the DVDP / VCR combo system 10 are externally present as one system, and the user may use a separate input device such as a remote controller 15 or a DVDP / VCR combo system ( By operating an operation panel (not shown) and the like provided on the front surface of the device 10, mode switching between the VCR unit 11 and the DVDP unit 12 and individual functions of the devices 11 and 12 can be operated.

The TVP 23 may be connected to the DVDP / VCR combo system 10 as a peripheral device for outputting video and sound reproduced by the DVDP unit 12 or the VCR unit 11 therein. In addition, an audio amplifier 21 is connected as a peripheral device for outputting the sound reproduced by the DVDP unit 12 of the DVDP / VCR combo system 10. In addition, an external device 25 such as a camcorder may be connected to the DVDP / VCR combo system 10. The DVDP / VCR combo system 10 receives a video signal and an audio signal from the external device 25 and records them on a magnetic tape inserted into the VCR unit 11 or outputs them to an image output device such as a TV 23. Do this.

FIG. 2 is a block diagram illustrating a connection state between output terminals according to characteristics of each signal for video signals reproduced by the VCR unit 11 and the DVDP unit 12 of FIG. 1. The DVDP / VCR combo system 10 is configured to output three kinds of video signals. That is, the luminance signal (Y) and two color difference signals (P _RY and P _BY) of the composite component (Component) signal, the luminance signal (Y) and two color difference signals (P _RY and P _BY) consisting of a color signal ( A super signal composed of C = P _RY + P _BY ), and a composite signal composed of the sum of the luminance signal Y and the color signal C (Y + C) can be output. The component signal, the super signal, and the composite signal may be transmitted to the TV 23 through three image output terminals 16, 17, and 18, respectively. However, the composite signal reproduced by the DVDP unit 12 is not used because the image quality is relatively poor compared to the component signal and the super signal due to the reproduction and recording characteristics of the optical recording medium such as DVD.

As shown in the drawing, when the DVDP unit 12 of the DVDP / VCR combo system 10 operates, the video signal is converted into a component signal or a super signal through video signal conversion. At this time, the component signals (Y, P _RY , P _BY ) are output through the component output terminal 17 provided with three output terminals, and the super signals (Y, C) are composed of seven pins and are made of one port. The jack is output through a super output terminal 16 provided to be inserted. On the other hand, the video signal reproduced by the VCR unit 11 is output through the composite output terminal 18 composed of one output terminal as the composite signal (N). The audio output is output through the audio amplifier 21 in the case of the DVDP unit 12 and output through an audio line (not shown) in the case of the VCR unit 11. In the drawing, the RF output terminal 19 is configured to output a high frequency broadcast signal Q obtained by high frequency conversion of a video signal and an audio signal reproduced by the VCR unit 11 while the TV 23 is set to channel 3 or channel 4. It is.

On the other hand, the DVDP / VCR combo system 10 does not output the super signal and the component signal output from the DVDP unit 12 at the same time, and is selectively switched by the user to the super output terminal 16 or the component output terminal 17. A slide switch 13 is provided. In addition, the TV connected to the DVDP / VCR combo system 10 should change and set the mode of display operation for the input signal according to the input signal. Accordingly, the signal corresponding to the mode set in the TV is output from the signals reproduced by the DVDP unit 12 of the DVDP / VCR combo system 10 using the slide switch 13. At this time, the slide switch 13 is provided with two connecting wires for outputting the super signals (Y, C), which are the same kind as the super signal among the component signals (Y, P _RY , P _BY ). It is used as a common connection line for transmitting any one signal P _RY or P _BY among the luminance signal Y and the color difference signal. The other color difference signal P _RY or P _BY except for a signal commonly transmitted to the connection line for transmitting the super signal among the component signals is connected to the component output terminal 17. Therefore, when the component signal is output, the DVDP unit 12 outputs the luminance signal Y and one color difference signal P _RY to the slide switch 13, and outputs the other color difference signal P _BY to the component output terminal. Output to (17).

Here, the slide switch 13 is designed to output the input signal to the super output terminal 16 or to the component output terminal 17 by a switching operation of the user. Therefore, when the signal reproduced by the DVDP unit 12 is set to be converted into a super signal and outputted, the slide switch 13 is switched to the super output terminal 16 by the user. When the signal reproduced by the DVDP unit 12 is set to be converted into a component signal and outputted, the slide switch 13 is switched to the component output terminal 17 by the user.

Therefore, the DVDP / VCR combo system 10 is configured to operate the slide switch 13 according to the type of signal, so that the user must switch the slide switch 13 every time the type of output signal is changed. Hassle occurs. In addition, the signal output terminals 16, 17, 18, and 19 and the slide switch 13 are generally arranged at the rear of the DVDP / VCR combo system 10, so that the DVDP / VCR combo system 10 is located in a narrow space. If the arrangement is inconvenient, the switching operation is inconvenient, and when the DVDP / VCR combo system 10 is moved for the switching operation, the arrangement is disturbed.

The present invention for solving the above problems is to selectively output the super signal (Y, C) and the component signals (Y, P _RY , P _BY ) reproduced by the DVDP unit 12 to the super output terminal 16 and the component output. It is an object of the present invention to provide a DVDP / VCR combo system that can be more easily output to the terminal 17.
