Background: A television program playback device for use in the home was unveiled Monday in Princeton, New Jersey.
The device, called 'Selecta Vision' (SV, for short), was develop by the RCA Corporation, a United States firm. Scientist William Hannan said that 'SV' will play colour television tapes through an ordinary TV set the "way we row play phonograph records or sound tapes."
The basic element of the system is two-dimensional holography - a tape of electronic photography using lasers to record images on transparent plastic tape. The recorded images - a colour television program in this case - are played back by passing the tape through a laser beam which 'develops' or realizes the recorded material. The images are picked up by a miniature TV camera and transmitted into the television set through its antenna system.
The U.S. company expects to put the SV on the market in 1972, retailing for approximately four hundred dollars. The pre-recorded colour television programs, one-half hour in length, will be contained in cartridges, or cassettes, costing approximately ten dollars each.
During the demonstration, Mr. Hannan pulled the TV camera away from the page and moved the laser with no visible effect on the pictures. He also showed how the tape could be stopped, reversed, and played in slow motion - also, again, with no effect on the pictures.
