1. A digital television receiver that receives non-real time (NRT) content, comprising in combination: a radio frequency tuner that receives a radio frequency modulated channel containing a transport stream over a tuned channel and demodulates the channel to produce an output transport stream; the output transport stream containing an Internet Protocol (IP) stream of packets containing non-real time content, a FLUTE file description table (FDT) and NRT metadata; an electronic storage medium; a demultiplexer that demultiplexes the IP stream of packets to produce: NRT content that is stored in the electronic storage medium, the FLUTE FDT, and NRT metadata; an FDT parser that parses the FDT to produce NRT file metadata from the FLUTE FDT; and an NRT metadata parser that produces NRT service metadata; NRT content description text and NRT content metadata.
