Abstract
A system for delivering content to users from a content provider including a transmission system for transmitting content in a series of segments and a plurality of receivers, each of the receivers comprising a memory, a processor, and an output driver. The memory may have stored therein instructions that, when executed, will cause the processor to perform the following steps: (1) comparing each of the received segments to any previously stored segments to determine whether each received segment has been previously stored; (2) for a particular received segment that has not been previously stored, storing the segment in the memory; (3) for a particular received segment that has been previously stored, determining whether the received segment is missing data and, if it is, retrieving the missing data, if available, from the corresponding previously stored segment; and (4) providing each of the received segments to the output driver along with any missing data retrieved from the memory. In preferred embodiments, the system is useful for enabling the smooth provision of content to a user as any missing data contained in a received data stream can be obtained, if available, in the memor…
