Abstract
This invention provides an information transmitting system using television luminance signal, including a data detecting stage for detecting data according to the change of amplitude of a luminance signal by comparing the level of the luminance signal averaged in one field of one frame with that of the luminance signal in another field after separating and averaging the luminance signal of television signal, and a data processing stage for processing the data extracted by said data detecting stage. By carrying out the character information transmission, easy data-receiving without an additional receiving system may be attained and applied to the conventional TV at low price by virtue of the simple circuit composition may be possible according to the present invention.
