Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a video information system in which a television receiver with a general remote control device (hereinafter referred to as a remote control) is used as an information terminal.

(Prior Art) In conventional information systems equipped with dedicated information terminals such as doorbells with surveillance cameras, dedicated receivers are provided to display images of each piece of information. Switching to the channel you want to receive is done by manually operating this remote control.Also, the above-mentioned receiver is usually always powered on, and it is used to receive information in emergencies such as fires, and to receive information on the doorbell when guests arrive. When receiving information from a surveillance camera, the user manually switches the channel on the receiver as described above.

(Problem that 51 Mei attempts to solve) Conventional video information systems are configured as described above, and even if the receiver is turned on, you have to manually operate the remote control to switch to the channel you want to receive. There was a problem that the operation was troublesome.

The present invention has been made in view of these problems, and allows automatic switching to the desired channel for image reception, eliminating the hassle of operation.

It also aims to provide a video information system that can use a general television receiver.

[Means for Solving the Three Problems] The video information system of the present invention includes a television receiver with a remote control device and a learning function for learning the control format of the remote control device. The control format shown in Figure 7 is equipped with a dedicated remote control terminal for controlling the television receiver.

[Effect]

In the video information system of this invention, the television stain 1
A special remote control terminal that has the function of learning the control format of the attached remote control (remote control device) is installed on the receiver. The television receiver is automatically controlled.

〔Example〕

FIG. 1 is a block diagram showing the story structure of the video information system according to the present invention. Reference numeral 1 denotes a general (commercially available) Previsi FL receiver equipped with a remote control 2, and a light emitting section 3 of the remote control 2 emits infrared light. 4 is a remote control end of the remote controller 2 which has a learning function to learn the control format, and is based on the system command from the system bus 5. The TV receiver 1 is remotely controlled using the learned control format. 6.7 is a light receiving part and a light emitting part that receive and emit infrared signal Z light, 8.9 is its receiving f, mi circuit and transmitting i 5 circuit, 1
0 is a cptB line that controls the whole, 11 is a data bus I/F (interface) for connecting with the data bus 5, 12 is a 7tt source circuit connected to a DC power supply, 13
14 is a remote controller for controlling the remote control terminal 4, and 15 is a light receiving and emitting part thereof.

Top 1: The self-reflection control shaft 4 is usually installed on the ceiling surface, so that the previsual receiver 1 can be placed anywhere in the room. Also, if you install the remote control terminal 4 on the ceiling, you can use a dedicated remote control! 4 are provided. Then, before the system starts operating, the control format of the remote controller 2 is set to seven remote control terminals 4. At that time, first, use the dedicated remote controller 14 to
is set in the remote control code learning mode, and then the remote control code of the remote control 2 is learned according to the determined child side. After the learning is completed, the remote control terminal 4 is returned to the normal mode.

When a system command comes through the data bus 5, the failure rate is 0.
4 Terminal 4 emits infrared light from light emitting unit 7 using the code learned above;
emit a signal light and control the television receiver l.

At this time, for example, if you have a visitor, the system will automatically switch to the channel that is transmitting video No. 13 from the doorbell's surveillance camera, and in the event of an emergency such as a fire, the system will also automatically switch to the channel with that video signal. toggle.

Further, infrared signal light from the remote control 2 of the television receiver 1 or the dedicated remote control 14 is photoelectrically converted by the light receiving section 6. This photoelectrically converted signal passes through the receiving 111 path 8 to the CP
The data is input manually to the U circuit 10, where data processing is performed.

The learned remote control code is stored in the memory within the CPU circuit 10, and the CPU circuit 10 transmits an infrared signal from the light emitting unit 7 to the television receiver l according to a system command from the data bus 5. At this time, since the data backup circuit 13 is provided, there is no problem even if a power outage occurs.

Figure 'frJ2 shows an example of the overall configuration of a video information system equipped with a queen remote control terminal 4.

In the figure, 16 and 17 are antennas that receive VHF broadcasting and LIHF broadcasting signals, 18 is an antenna that receives satellite broadcasting, 19.20 is a surveillance camera that can be installed in any room, and 21 is a surveillance camera installed in a doorbell. camera,
Reference numeral 22 denotes a video processing device No. 44 that processes video signals from the above-mentioned parts and outputs system commands. A VTR 23 with a general remote control 24 is also connected to this video signal processing device 22. A coaxial cable 25 is connected to the video signal processing device 22 together with the data bus 5, and multiplexed signal transmission is performed by frequency division of RF41°. 26.27
28 is a day play phone dedicated to the home media system, which is connected to the data bus 5, and is a machine number control device for lighting, household appliances, etc., and a home information control device, such as security.

The Kamikita video signal processing device 22 is equipped with a satellite broadcast receiving adapter, and performs image processing such as superimposing, screen division, acid inclusion, pictograph (icon) display, etc. It also performs Shinryu conversion. Additionally, this system is equipped with a videophone function, a FAX function, an answering machine function, and other double-image display functions.

Here, the operation of the remote control terminal 4 is entirely performed by the CPU circuit IO.
The execution operation of the 1h1 program is 1-61.
You can switch to the channel you want to watch on the job, so the operation is simple, and you can use a general television receiver 1.

Note that the control of each device described above in item 4.3, sending and receiving, is not limited to the infrared method, and may be any other method. Further, the manual command input to the remote control Dg terminal 4 is not limited to the bus method, and there is no restriction on the format of the remote control 2 either on the side or on the side of f1. Historically, the internal configuration of the remote control terminal 4 is not limited to the circuit configuration shown in FIG.

〔Effect of the invention〕

As described above, according to the present invention, since the television receiver is equipped with a dedicated remote control terminal that has the function of controlling the remote control attached to the television receiver, it is easy to switch to the channel that you want to receive while working at work.
