  • Patent number: 3944993
    Abstract: A character generator system suitable for creating a character display on the screen of a standard TV receiver is disclosed. The character generator system includes a sync generator which generates timing and synchronizing signals that create a 263 line, non-interlaced, roster. The character generator system also includes a character generator adapted to receive binary signals that define the character display. The character generator is timed and synchronized by the sync generator so as to create a charater video signal suitable for creating the character display as the screen of the TV receiver is scanned. Color is added to the character video signal by a chroma generator in a manner such that the background is in one color and characters are in another color. The 263 line raster (non-interlaced) results in a color display without color fringing.
