After a review of the various electronic techniques which have been used in television to simulate optical effects used in motion picture photography, a new process called "Chroma-Key" is described. "Chroma-Key" is an insetting or matting technique intended for color television which utilizes a highly saturated color background for the inset subject. Many of the problems normally associated with monochrome inset are nonexistent with the new approach. The apparatus required, methods of integration into a system, consideration of various influencing factors, and results of tests and on-the-air use are described.
