Abstract

PURPOSE:To expand the system by providing a display data of each device to each device and switching a picture signal from each device with a picture signal changeover means of a system controller so as to send a television receiv er. CONSTITUTION:When a control input of a remote control transmitter 4 relates to a picture display of a video tape recorder 5, a control signal generating section 5-10 of the video tape recorder 5 reads a relating picture from a display data memory 5-12. Then a picture signal generating section 6-11 converts the signal into a picture signal and gives it to a picture signal changeover switch 3-8 of the system controller 3 from a terminal 5-16. In the case of the display relating to the video tape recorder 5, the changeover switch 3-8 is controlled by a control signal generating section 3-3 so as to be connected to a terminal 3-17. The output of the switch 3-8 is given to a terminal 2-14 and the video signal and the picture signal are synthesized by a changeover section 2-5 and displayed on a CRT 2-6.

The system controller 1-roller 3 decodes the operation signal from the remote control transmitter 4 using the remote control amplifier 3-5, waveform shaping section 3-6, and code decoding section 3-7, and sends input data to the control signal generating section 3-3. send. Control signal generation 3-3
discriminates the input data and receives the television image from terminal 3-10. Control data is sent to the control signal generating section 510 of the video recorder 3 from the control signal generating section 2-7 of 12 and, for example, the terminal 3-20. Also remote control transmitter 4
If the operation signal from the system requires pictograph display, the system controller 1'/roller 3's display data memo 3-
The corresponding display data is read from 2, the picto signal generator 3-11 generates a video signal for one screen, and the terminal Y311 outputs a digital signal from the terminal Y311. 3! to the switching section 25 of the receiver 2! ,S,C
, displayed on RT2-6. Furthermore, the deoteare: 1
The reproduced video signal obtained by the playback head 5-9 of the player 5 is transferred from the end i' 5-14 to the video signal change switch 3-1 of the system controller 3 and selected.
After that, the end: (-3-9) is sent to the manual changeover switch 2-23 as the video input (A-'') of the television receiver.

Problems to be Solved by the Invention However, in such a display device, the equipment constituting the system is fixed by the display data memory 3-2 built into the system controller 3, and the system is not expandable.

The present invention is intended to solve the above problems, and aims to provide an on-screen display device that enables on-screen display with system expandability.

Means for Solving the Problems In order to solve the above problems, the on-screen display device of the present invention has display data for each device constituting the system, and displays character patterns (pictures) indicating the operation details required for each device. ) is provided as a video signal output.
- Provides switching means for sending the signal to the television receiver.

Effects With the above configuration, each device has display data and generates pics 1 to 1 as video signal outputs in accordance with operation inputs such as remote control signals, so the system can be easily expanded.

Example An embodiment of the present invention will be described below based on the drawings.

FIG. 1 shows a block diagram of an on-screen display device according to an embodiment of the present invention, and similarly to FIG. It is equipped with a recorder 5. The difference from FIG. 2 is that the system controller 3 has a display data memory and a picto signal changeover switch 38 instead of the picto signal generator, and the video low = 1-5 is the picto signal generator 5-11 and the display It has a data memory 5-12.

In FIG. 1, the process until the control signal generator 3-3 of the system controller 3 operates in response to the manual operation from the remote control transmitter 4 is the same as the conventional system shown in FIG. The operation input of the remote control transmitter 4 is from 21 to the top of the video cheap recorder 5.
If it is related to display, Video Cheap Recorder 5
The control signal generating section 5-10 of the display data memory 5-12
I read the corresponding pictogram, and pin 1 to signal generator 5
-11, it is converted into a picto signal and sent to the picto signal changeover switch 3-8 of the system controller 3 from a terminal 5-16. The picto signal changeover switch 3-8 is 3 in the embodiment.
Although the circuit is switched, a large number of switching circuits may be provided in consideration of system expandability. In the case of Table 1 relating to the video tape recorder 5, the picto signal changeover switch 8 is controlled by the control signal generator 3-3 so as to be connected to the terminal 3-17 side. , = (7:
) When the system controller I-Roller 3 video signal switching switch 3-1 is connected to the video chip recorder 5 video (No. 4 selection terminal 3-14), it will not work, because , video tape recorder 5 while viewing other video signals not shown or making up the system 4.
This is because it becomes necessary to display on-screen information regarding the table size. Picto signal changeover switch 3-8
The output of i'fl+2'' is switched through terminal 2-14.
-5, the video signal and picto signal are combined, CR1'2
It will be shown on 6th.

Effects of the Invention" 2. According to the present invention, although the number of devices constituting the system is limited by the number of circuits of the system controller Pino 1 to the signal switching means, the display data of each device can be individually controlled. The PIC I-signal from each device is switched by the PICT signal switching means of the System CON I-+ Coke 3 and sent to the television receiver, making it possible to expand the system. A screen display device can be realized.
