Abstract

PURPOSE:To allow characters and graphic information to be used by a popular television receiver and to keep said characters and graphic information by a hard copy by reading optically the characters and graphic information indicated by binary codes at one part of a television screen. CONSTITUTION:A receiver is constituted with the part, which optically reads characters and graphic information indicated with binary codes at one part of a television screen and converts them into an electrical signal, the part which processes the electrical signal and an outputting device to inform contents of infromation of the outside. For example, in terms of a binary code receiver utilizing television broadcasting, binary codes are displayed every field according to the prescribed display method. A photoelectric conversion circuit 1 reads optical signals and converts them into electrical signals. Moreover an A/D conversion circuit 2 converts them into binary signals. Due to the signal from a timing generating circuit 4 a signal processing circuit 3 fetches these binary signals. Contents of this information are given to the outside through an outputting device 5.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a binary code receiving apparatus using television broadcasting that can be used for general television broadcasting.

Conventional structure and problems With the development of information communication, characters and
There is an increasing demand for transmitting graphical information and preserving it in hard copy. There is a device that extracts information directly from the circuit of the television receiver as this receiving device u (1),
It is desired to develop a receiving device that can be used in commonly used television receivers.

OBJECTS OF THE INVENTION It is an object of the present invention to provide a /(-binary code receiving device) that utilizes television broadcasting and can be used in commonly used television receivers.

Structure of the Invention In order to achieve this object, the binary code receiving device using television broadcasting of the present invention optically reads character and graphic information presented in binary code on a portion of a television 1114i image and converts it into an electrical signal. It consists of a converting section, a processing section for the electrical signal, and an output device for informing the outside of the information. By optically reading a binary code presented on a portion of a television image, the present invention can be used in commonly used television receivers.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to one drawing.

The drawing shows a block diagram of a binary code receiving apparatus using television broadcasting according to an embodiment of the present invention. In the drawing, 11'i is a photoelectric conversion circuit that optically reads binary codes such as characters and figures presented on a television image and converts them into a vaporized amount; 3 is an A/D conversion circuit that converts the signal into a digital signal; 3 is a signal processing circuit (for example, a microcomputer) that processes the output signal of the A/D conversion circuit 2 and controls an external device; 4 is an A/D conversion circuit;
a timing generation circuit that generates the timing for taking in the output signal of the D conversion circuit 2 to the signal processing circuit 3; , 6.7 are a notator bus and a control bus between the signal processing circuit 3 and the output device 5, respectively.

The operation of the television broadcast/hybinary code receiving apparatus configured as described above will be described below. first,
Generally, binary codes are presented in a field unit to a portion of a broadcast television image using a prescribed presentation method. A photoelectric conversion circuit 1 reads this optical signal and converts it into an electrical signal,
Furthermore, the A/D conversion circuit 2 converts it into a binary signal. In response to a signal from the timing generation circuit 4, the signal processing circuit 3 receives this binary signal. The contents of this information are communicated to the outside through the output device 5.

As described above, according to this embodiment, it can be used in a generally popular TV receiver by optically reading the binary code presented on a television image.

Effects of the Invention As described above, the present invention can be used in commonly used television receivers by optically reading character and graphic information presented in binary code on a portion of a television image. It has practical value, as it allows text and graphic information from broadcasts to be preserved in hard copy.
