ABSTRACT:
Information transmitted through wireless communications formed by information transmission lines from artificial satellites and radio towers or through wired communications established by cables is categorized into four categories. The individual information is transmitted in a broadcasting mode in synchronization with the information transmission timing defined for each individual information category. The information receiver captures and edits the received information and provides output for the service client in the manner associated with the individual category corresponding to the received information. Category-4 information is transmitted with the highest priority immediately when the information is generated; Category-3 information is transmitted periodically, for example, every five minutes; Category-2 information is transmitted at a time slot when the transmission line is relatively unoccupied; and Category-1 information is transmitted at a time slot when the transmission line is least occupied.
