Abstract
Abstract An information display apparatus which accumulates arbitrary information inputted to a television receiver from the outside, superimposes the information in a memory on an ordinary video signal and displays the superimposed image on a television display in accordance with a calender timer built in the television receiver. A remote control unit is provided for inputting information to the information display apparatus from the outside. Memories are disposed in the information display apparatus and the remote control unit for accumulating arbitrary information. A calender timer is provided for serving as a reference for displaying information are also disclosed. Arbitrary information inputted from the outside can be displayed on a television display at a previously appointed date.
