Abstract

PURPOSE:To display a designated program without any waiting time as to a program and a page stored already by storing only a program and a page within a prescribed range in advance. CONSTITUTION:A television video signal inputted from an input terminal 1 is subject to extraction of a teletext signal by a data/clock generating circuit 4 and converted into a digital signal. Then a program data per 1Vd is stored in a packet buffer 7 via a BEST 6 and a teletext signal is subject to picture processing and transferred and stored in a pattern memory 15. A page within a prescribed range of a program within a prescribed range is stored as it is in the teletext signal memory 15 even after power interruption. In selecting a program number stored already by a remote controller 30, it is extracted from the teletext signal memory 15 and the designated program is displayed.
