Abstract
A system and method for distributing video or audio or other interactive program information to multiple users includes master files of such program information that can be selectively distributed to community systems in which individual users are selectively coupled with computing microcells that process the selected program information from within the entire set of programs that are all contained in moving memory modules which cyclically and recurringly distribute the entire set of programs to multiple computing microcells. A microcell access switch controls coupling of users to computing microcells, and controls selective interaction between master files and moving memory modules for updating the set of programs stored therein. The microcell access switch provides network programs to users without requiring a computing microcell for enhanced versatility and reduced system costs.
