Abstract
A user device receives, from an application server, a catalog of available content. The catalog of available content includes content available for delivery via multicast over a broadband wireless spectrum. The user device provides, to the application server, an indication of a user's selection of particular content available for delivery via multicast over the broadband wireless spectrum. The user device receives, from a content server, the particular content via a multicast transmission over the broadband wireless spectrum. The particular content includes multiple individual segment files. The user device detects a corrupted or missing segment file from the multiple individual segment files and requests, from the content server, a replacement segment file corresponding to the corrupt or missing segment file. The user device receives, from the content server, the replacement segment file via a unicast transmission to provide a complete set of segment files for the particular content.
