Abstract
Embodiments provide bandwidth efficient mechanisms for delivering data to a receiver device via a wireless broadcast network such that data may be assembled in the receiver device for use by a local application. In the various embodiments, data files may be broadcast as content elements via the broadcast network using the FLUTE protocol during a FLUTE session. In an embodiment, the content elements may be broadcast according to a broadcast schedule that may identify a time at which the content elements will be broadcast and the broadcast schedule may be communicated in a file delivery table (FDT) transmitted during a FLUTE session.

A method for broadcasting content in a File Delivery over Unidirectional Transport (FLUTE) Protocol session within a broadcast network, comprising:
- receiving content comprising a plurality of content files;
- assembling the content files into a FLUTE session having a first channel and a second channel;
- scheduling broadcast times and channels for the content files included in the FLUTE session;
- generating a first file delivery table identifying the scheduled broadcast times and channels for the content files in the FLUTE session;
- broadcasting the first file delivery table during the FLUTE session over the first channel;
- and
- broadcasting the content files at the times and on the channels identified in the first file delivery table during the FLUTE session.
