Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television receiver used in ordinary households.

[0002]

2. Description of the Related Art Conventionally, a television receiver used in general households has an image display function having a function of displaying an image on a cathode ray tube, an audio function of outputting sound from a speaker, and a video of a VHF or UHF signal. It was composed of a VHF / UHF tuner function for demodulating a signal and an audio signal. In such a television receiver, for example, when displaying a reproduction signal of the video tape recorder, the television receiver and the video tape recorder are connected using a video cable and an audio cable. In recent years, in addition to the previous VHF / UHF broadcasting, new broadcasting such as satellite broadcasting (hereinafter referred to as BS broadcasting), text broadcasting, CS (Communication Satellite) broadcasting, and high-definition broadcasting has started.
In order to watch the broadcasts of these new systems on the television receiver having the above-mentioned configuration, a BS tuner, a teletext adapter, a CS tuner, and a Muse-NTSC, respectively.
An external device called a converter (hereinafter, referred to as an M-N converter) is used as in the case of the video tape recorder.
It was necessary to connect to a television receiver. An example of such a connection method is “NHK TV technical textbook (below)”.
(Published by Japan Broadcasting Corporation, Issue 3 September 20, 1991)
It is described in P.267 to P.269.

[0003]

However, in order to mount a large number of external devices having the above-mentioned functions, it is necessary to install a large space for the external devices, and it is necessary to connect a large number of video cables and audio cables, which is a mess. Becomes

Therefore, recently, some of the functions of the television receiver having the function corresponding to the above-mentioned new broadcasting system, that is, the BS tuner, the teletext adapter, the CS tuner, and the MN converter have been incorporated. Television receivers also exist. A television receiver having such a function is convenient because it does not require a place to store an external device and does not need to connect a video cable, an audio cable, etc., as compared with a method of connecting an external device. On the other hand, when the user of the television receiver wants to add new functions such as Picture-in-Picture (hereinafter referred to as PinP) function and stereo surround function, the receiver of the television receiver can be used. It has the disadvantage that it needs to be replaced and waste increases. In addition, the above-mentioned multi-functional television receiver has drawbacks that it is difficult to disassemble and the disposal cost is high.

An object of the present invention is to eliminate the above drawbacks.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention has a module configuration of each function and a configuration in which these modules can be built in the main body of the television receiver, and each module is provided according to the need of the user. I was able to select.

[0007]

With the above means, when a new function is required, a module can be added to the television receiver so that the function can be easily added without replacing the television receiver body. You can

Further, by replacing the module with a high performance one, the performance can be easily improved without replacing the television receiver main body.

When a module fails, it can be repaired by repairing or replacing only that module, which is easier than repairing or replacing the entire television receiver.

As a result, there is an effect of reducing waste.
Further, when it is discarded, it is easy to disassemble, and there is an effect that the disposal cost can be reduced.

The module 21, the module 22, the module 23, the module 24, and the module 25 are modules each having a different function, and can be easily removed from the television receiver main body 1. The lid 31 is attached to the portion where the module is not attached so that dust or the like does not enter. With this structure, when the user wants to add a new function, the function can be easily added by removing the lid 31 and attaching a necessary module. Also, the performance of the television receiver can be improved by replacing the already installed module with a high performance one.

(Second Embodiment) FIG. 2 shows an example of a module according to the present invention. The module 21 in FIG. 2 has a VHF / UHF tuner function. In FIG. 2, 211 is a power switch, 212 is a pilot lamp, 213 is a light receiving part of a remote controller, 214 is a channel display part, 215 is a circuit part, and 216 is a bus. In this embodiment, when the function of the module 21 is not used, the power switch 211 can be turned off to suppress unnecessary power consumption.
