A Graphic Quality Character Generator for Television Titling
Stéphane Baron · Journal of the SMPTE · 1971
The most widely used method of introducing titling into programing is by superimposition. A second technique is the utilization of character-generation devices. The character generators previously available were designed primarily to make computer generated characters compatible with the TV scan. The system, the Vidifont, synthetically reproduces a graphic arts style character with sufficient resolution to be compatible with the superimposition technique. Major design considerations are discussed including system considerations and font design and character size. The Vidifont provides four basic functions: interface, timing and control, storage and character generation.
