摘要:
A software application program that intelligently interfaces with a statistical data recording program, mass data storage devices and programmable electronic display devices to monitor the situational current state of a real-time event or activity such as a sporting contest and to identify, select, compile, organize, prioritize, present and recommend a plurality of relevant data items compiled from a plurality of recorded data sources to provide visual display content for selection by an operator for display on one or more electronic display boards. The intelligent interface software application program enables an operator of a programmable electronic display device instantly to review and select relevant data items corresponding to a given situational current state of a real-time event or activity and transmit selected data items for display on electronic display boards to a viewing party or public.
