Abstract
Techniques for fragmenting a file or a collection of media data are disclosed. According one aspect of the techniques, a file pertaining to a title is fragmented into a header and several tails or segments. The header is a continuous portion of the file while the segments are respective parts of the remaining portion of the file. The header is seeded substantially in all boxes, and none, one or more of the segments are distributed in each of the boxes in service. When a title is ordered, the header is instantly played back while the segments, if not locally available, are continuously fetched respectively from other boxes that have the segments.
