ABSTRACT:
A method and apparatus are provided for implementing transfer of files to receivers in a digital broadcast system. The data files are partitioned into segments that are interspersed in a broadcast signal. Segment headers are provided to indicate the number of segments that constitute a corresponding data file and to uniquely identify each of segment in a data file. Receivers allocate memory to store segments for a selected data file based on data in the segment headers. The headers can be provided with data to address data files to selected receivers. Receivers are programmed to monitor the progress of storing segments of a selected data file during an initial broadcast and to use rebroadcasts to complete a file transfer.
