Abstract:
1. A method of distributing files to remote receiving units, comprising the steps of: creating a file broadcast schedule that identifies a plurality of files and that includes scheduling information indicating when the files will be transmitted; sending the file broadcast schedule to a number of remote receiving units via wireless transmission; analyzing the file broadcast schedule at one or more of the remote receiving units by identifying at least one specific file intended for receipt and storage at that receiving unit and by determining from the scheduling information a scheduled time at which the specific file is intended to be received, wherein the identifying step further comprises identifying the specific file based on at least one unique identifier that is contained in the broadcast schedule and that is associated with the specific file; monitoring a digital satellite transmission channel at the scheduled time for the specific file; and upon receiving the specific file, storing it at the remote receiving unit; wherein the analyzing, monitoring, and storing steps are carried out at the remote receiving unit without user interaction; and wherein the at least one unique identifier comprises one or more station identifiers that identify one or more corresponding remote receiving units, and wherein the file broadcast schedule includes, for each file, a file identifier and at least one of the one or more station identifiers, and wherein said analyzing step further comprises identifying the one or more specific files at least in part by comparing the at least one station identifier to a station ID assigned to that remote receiving unit.
