Abstract
Authorized decoders (60) are provided with enable reception keys (66) so that subsequently transmitted data having an information identification code matching (65) a reception key (66) at a decoder-receiver may be retrieved for subsequent display on the video screen. Tile messaging (72.1) and cellular micrographic transmission techniques are used to reduce the volume of data transmitted to change update data, wherein cells (72.1) of characters are transmitted as one byte of data and cells (72.1) of pixel data are transmitted a plurality of bytes of data. Each decoder-receiver (60) may have a plurality of video screens separately and uniquely identified such that encoded update data and other messages are transmitted for specific video screens. The system includes multiplexing financial market information and television program information signals, and transmitting the multiplexed signals to the decoder-receivers for selectively displaying different combinations of information.
