Abstract

A procedure for selecting and storing data elements communicated from a common database to users of the database utilizing a communication link between each transmitter and a concomitant receiver accessible by the user. The transmitted information is augmented with attributes which are used at the receiver to select and then store locally only that information of interest to each receiver'"'"'s user, wherein the attributes and the user selection pattern determine the criteria for storing information locally. Attributes include: utility of each data element in time; interest categories and level of interest for each of the categories determined for the collective users; repeat time to the data element; and a hyperlink to associated data elements.

grouping the data elements with the corresponding interest categories and the corresponding data attributes to thereby produce the common database, and

broadcasting the common database to the plurality of users.

2. The method as recited in claim 1 wherein at least one data element is indicative of physical parameters to control a display device deployed by each of the users.
