Abstract

PURPOSE: To reduce the signal process speed and thus to increase the stability by providing the means which samples the information piled in the vertical flyback time of the TV signal for memorization into the memory and then separates and identifies various types of information from the sampled and memorized information
CONSTITUTION: The information piled in the vertical flyback time of the TV signal and necessary for transmission of the characters and the like is sampled through sampling circuit 20 and then supplied to input buffer 3 and start pulse detection circuit 4. The reading clock is supplied to buffer 3 from reading clock generation circuit 7 by the command given from circuit 4, and the character information is read into buffer 3. When the reading of buffer 3 ends, the program code is read out and then compared with the data of program selection circuit 17 at decision circuit 13 to decide whether the character signal of buffer 3 is the control line or the pattern line through gate controller 15 and line decision circuit 14. And the case of the control line, the information of buffer 3 is stored in character signal memory 23, and in color signal memory 24 in the case of the pattern line respectively. After this, the information is displayed at CRT via the display address and the display clock signal.
