IMPROVEMENTS RELATING TO TRANSMISSION AND RECEPTION OF DATA BY TELEVISION

摘要

The teletext television receiver has a circuit to make the decoder unselective for one digit in the page-number input code. The acceptance signal can be released independently of the value of the digit or every such digit of the page-number input code. (The acceptance signal, sets the receiver, to accept the incoming page for display). The circuit also makes the docoder unselective for the magazine-number code. The AC acceptance signal can therefore be released independently of the value of the magazine-number code.
