A teletext decoder extracts digital information from a video signal for displaying graphics and textual information embedded in the video signal. The decoder includes a prefix processor responding to user supplied commands for selecting and storing the pertinent embedded information into a memory. The microcomputer reads the data provided by the prefix processor, converts it to pixel words representing picture elements and restores the converted data into the memory. The decoder includes a display processor which reads more than one pixel word at a time when accessing the memory, and translates each pixel word to 3 groups of color codes and to a one-bit transparency code.
