Abstract

PURPOSE:To successively display the next page of the display of a fixed program by storing a teletext signal in a memory, longitudinally scrolling the whole display of the fixed program, reading out it and displaying it. CONSTITUTION:The teletext signal is extracted from a television video signal inputted from the input terminal (video input) 1 of the television video signal by a data clock generation circuit 4 and also converted to a digital signal. Program data per one Vd is stored in a packet buffer 7 through a BEST 6. Before the next Vd term, the program data stored in the packed buffer 7 is successively transferred to a main memory 15 for storing the program data and stored in it by a main CPU 9. When the program number of the targeted teletext is selected by a remote control 30, the program data stored by the main CPU 9 is extracted from the main memory 15 and image processed. Then a little more program data than that for one screen is stored once in an auxiliary memory 26. The screen is switched to display the program by longitudinally scrolling program area with the aid of the command from a program ROM 11 and the control by the main CPU 9.
