Abstract

PURPOSE: To simplify the constitution of the display unit as well as to ensure the application in a wide range by replacing the logic part with the microprocessor.
CONSTITUTION: The 1-line equivalent character signal piled during the vertical flyback time of the television signal is memorized in buffer memory 7. Decision signal DS memorized in the first half of shift register 7 among the character signals is written into random access memory 10 via input control circuit 15, and thus a comparison is given between signal DS written into memory 10 via microprocessor 8 and the contents memorized in read-only memory 9. In this case, if it is decided that picture signal V is included in signal SD, the picture signals equivalent to one picture frame are memorized in main memory 16 to display the character images on the display unit. While in case program signal PS is contained in signal DS, signal PS is written into memory 12. And processor 8 executes the program signals and displays them.
