ABSTRACT:
A teletext receiver has a television signal input circuit for receiving a television signal including teletext data signals. A teletext signal processor decodes the teletext data signals and obtains teletext data which is stored in a teletext memory. A teletext picture according to the stored teletext data is displayed at half size on one half of a display screen by reading out the teletext data from the memory at twice the speed normally used for displaying the teletext picture on the full screen. The teletext signal processor decodes teletext data for two pages which are displayed on the screen. Pages with numbers are identified in one of the two pages displayed on half the screen of the display, and if any one of these page numbers is selected, the teletext picture of the selected page is displayed on the other half of the screen. The teletext receiver may further comprise a picture in picture processor for generating video picture of smaller size than half of the screen size, and the display displays the small size video picture on the other half of the screen.
