Abstract
Digital data information is transmitted during at least one whole frame in television format, for the display of a television frame of alpha-numeric characters. The digital information is fitted to television lines with check bits at the end of each line. Successive fields of a frame carry the same digital information for redundant verification of accuracy. Microprocessors control processing of the information at both transmitting and receiving locations, coactively with memories. An identification code is provided for each frame.
