Abstract
Disclosed is a multipage display apparatus which divides one screen into several sections so as to display a plurality of pages at the same time. The apparatus comprises a microprocessor, a teletext unit for outputting signals R, G and B in unit of one page, a first encoder for encoding the signals R, G and B and outputting a composite video signal in the normal mode, luminance and chrominance difference signal separators, a controller and a memory unit for reading and writing the converted digital luminance and chrominance difference signals, a second encoder for encoding information read out all at once from the memory and outputting a composite video signal of a multipage mode, a window signal generator for receiving a synchronizing signal from the synchronizing and sampling frequency separator and generating a window signal, and a switch unit in which the composite video signal of either a normal mode or a multipage mode is selected by the window signal. In the apparatus, a plurality of pages are displayed at once on one screen divided into several smaller sections, thereby improving the efficiency of information search.
