Description

Messaging tv

The present invention relates to a device capable of displaying a character of a television, and more particularly, to store a user's message in a graphic similar to the teletext in a video signal output to a CRT, and the message can be reproduced by the forwarder to receive the message. It is about a message delivery television.

In general, when a message is to be transmitted from a television, a character is represented by controlling a color signal for displaying caption information to be displayed instead of an image signal by using an on-screen display device for displaying caption information in a predetermined area of the screen.

However, this could only be used under the control of the remote controller (REMOCON), and since it is represented using the on-screen display device, the amount of message data that can be stored is extremely limited, such as setup function when scheduled recording in connection with video. In addition, it is possible to explain only the functions of the television with the stored data, and there is a problem that it is difficult to convey the exact meaning even if a message is left.

Accordingly, an object of the present invention is to solve the above problems and to devise a device that allows a user to leave a message to another sender using a data storage means of a television, a color signal conversion means, and the like. It is connected to and controlled by the keyboard, and the keyboard and data converter, which are input means for inputting message data from the keyboard, are connected to the video signal output switching unit and the microcomputer, respectively, so that a message can be input from the keyboard. It is to provide a message delivery television that allows for text processing with graphics similar to teletext.

1 is a block diagram showing the configuration of the message delivery television of the present invention.

Referring to the accompanying drawings in order to achieve the object of the present invention as described above, the configuration, operation and effect will be described.

As shown in the figure, the message delivery television according to the present invention extracts information by rectification from an image intermediate frequency and the like and amplifies the image detection amplification means 10 for optimal gain so that it can be reproduced in a CRT. In a television outputting a known video signal composed of a switching means 40 and a cathode ray tube 50 for switching and outputting a video signal from the amplifying means 10, message data for executing a message-only program at the time of storing and reading a message. An input means 100 and a message data input from the message data input means 100 are stored exclusively, digital data are converted into analog color signals, and are processed by a selection signal from the message data input means 100. Microcomputer 20 including a message dedicated logic, input from the message data input means 100 Counting is composed of the switching control means 30 outputs to the switching means 40. The switching control signal by the output signal of the control signal of the microcomputer 20 and data.

The message data input means 100 includes a message key 60, which is a foreign key for executing a message-only program at the time of storing and reading a message, a remote control transmitter 90 for outputting message data, and a remote controller transmitter 90. And a receiving unit 70 for outputting message data from the microcomputer 20, and a keyboard 80 for inputting message data.

Referring to the operation of the present invention configured as described above in detail as follows.

First, the image detection amplifier 10 detects and amplifies only an image signal at an input image intermediate frequency so as to be reproduced on a screen, and is synchronously output from the image detection amplifier 10 by a channel selection signal of the microcomputer 20. The video signal of the corresponding channel is output from the video signal output terminal CV through the switching unit 40 to the CRT 50.

This is a process in which an ordinary television outputs an image signal.

At this time, when the user wants to leave his message, the message key 60, which is an external pushbutton key, is operated in an on state.

The microcomputer 20 recognizes this by the message key acknowledgment means, operates a message dedicated logic set inside the microcomputer 20, and switches to the ready state to handle the message processing.

The switching unit 40 is switched off by the switching control signal output from the switching control unit 30 under the control of the microcomputer 20, and switches so that the message data can be output from the microcomputer 20.

The microcomputer 20 receives the message data of the receiver 70 by the switching controller 30 through the transmitter 80 and the receiver 70 of the keyboard 80 or the remote controller, and stores the message data of the microcomputer 20. Store in

At the same time, by the control of the microcomputer 20, the message data digitalized at a certain time point is converted into an analog color signal by the D / A converting means, thereby being converted into a color carrier signal, and the control signal of the switching control terminal SW. Is applied to the switching unit 40 to output a color signal from the microcomputer 20.

Thus, if the data is separated by a given menu in the message dedicated logic of the microcomputer 20, the user can accurately write the desired message data through the CRT.

When the user's message data is all set, the microcomputer 20 turns off the message key 60 to save the stored message data and returns to the original screen, and the microcomputer 20 switches the light emitting diode means D1. To indicate that a message exists.

In addition, when the sender wants to receive a message, first, check whether the light emitting diode means D1 is turned on, and when trying to check the contents of the message, the message key 60 is operated to send the message to the microcomputer 20. Switch to the ready state for processing.

When the microcomputer 20 switches to the message processing ready state, the microcomputer 20 performs a message processing logic to switch the switching unit 40.

The message data corresponding to the menu designated by the storage means for storing the message data of the microcomputer 20 is converted into the analog color signal RGB through the switching controller 30 and then the switching control terminal SW of the switching controller 30. The switching unit 40 is enabled by the signal of (), and the message screen is combined with the video signal input through the video detection output unit 10 and displayed on the CRT 50.

As described above, the present invention is controlled by the logic and arithmetic processing and storage means of the microcomputer in the television, and stores a large amount of data by using the keyboard and the data converting means in the microcomputer, which are means for inputting message data from the keyboard. And the user's message can be output as a graphic similar to the teletext on the video signal output to the CRT by the remote control of the transmitter has the effect of conveying the exact meaning of the message.
