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. The decoder includes a common memory for storing the digital words provided by the prefix processor and a microcomputer capable of reading from and writing to the common memory. The microcomputer reads the data provided by the prefix processor, converts it to digital words representing the picture elements and stores the converted digital words in the common memory. The decoder includes a display processor which reads the converted digital words from the common memory to drive an image display device.
