Non-real time services

A digital television receiver that receives non-real time (NRT) content, comprising in combination:

• an Internet protocol (IP) receiver that receives a stream of IP packets and selects an IP subnet containing a packet stream selected as an output packet stream;
• the output packet stream containing non-real time content, a FLUTE file description table (FDT) and NRT metadata;
• an electronic storage medium;
• a demultiplexer that demultiplexes the IP packet stream 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 and NRT content metadata.

A digital television receiver that receives non-real time (NRT) content, comprising in combination:

• a receiver device that receives a signal and produces 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.
