PURPOSE:To reduce the possibility of supervision information left unextracted while being inputted at any time independently of the state of a display device by providing a supervision information processing means analyzing supervision information inputted till a reception enable signal is received, counting and holding its change and adding the count information to the display information. CONSTITUTION:A supervision device 111 and a supervision information processing means 113 analyze supervision information 101 inputted till a reception enable signal 103 is received and count and hold its change sequentially. When the device 111 edits display information 105 based on the supervision information received, the count information is added via the supervision information processing means 113. Thus, accurate display information is edited and the missing of extraction of the supervised information 101 inputted till a reception enable signal 103 is received is reduced. |
