Abstract
A multiple channel television display system suitable for receiving information (data) from a variety of sources and selectively displaying the information as alphanumeric characters on a plurality of television channels is disclosed. The information sources may be newswires, stock report wires, remote or local keyboards, temperature probes, etc. The information is received by computer control logic which feeds information to and receives instructions from a suitably programmed general purpose digital computer. The computer, in accordance with the information received by it relating to the receipt of information by the computer control logic from the various information sources, selectively interrogates the computer control logic to receive, in accordance with a priority arrangement, the information from the various information sources. The information from the various sources received by the computer is edited, if necessary. The computer instructs the computer control logic in a manner such that a different alphanumeric character display is generated on the picture tubes of connected television sets for each of the plurality of channels. In addition, the alphanumeric character displays can be made to appear to move (scroll) upwardly or downwardly, or they can be made to appear as consecutive pages on the display.
