Abstract

Systems and methods for systems and methods for reliably broadcasting content to a plurality of users and facilitating distribution of portions of the broadcast content that either were not received by particular users, or were received with errors. In one embodiment, a wireless communication system is configured to broadcast content from a content source to a plurality of user devices. The content source is configured to provide the content to a base station. The base station parses the content into a plurality of segments and associates sequential identifiers with each of the segments. The content is then broadcast to each of the user devices. An identifier of an alternative data source is also provided to the user devices. When a mobile station receives the segments, it examines the segment identifiers to identify missing segments. The segments are then retrieved from the alternative data source identified by the base station.
