Non-real time services

A digital television broadcast system, comprising:

• a transmitter that generates a digital television broadcast signal having one or more transport streams;
• where the data in at least one of the one or more transport streams supports Non-Real Time services by incorporating:
• an Internet Protocol stream of packets containing Non-Real Time content including a FLUTE File Description Table,
• a Non-Real Time Information Table, and
• a Service Map Table;
• and
• where the Non-Real Time Information Table contains a Content Identifier that relates the Non-Real Time Information Table to the FLUTE File Description Table.

• where the one or more transport streams contains an Internet Protocol stream of packets containing Non-Real Time content, the FLUTE File Description Table and Non-Real Time metadata;
• where the Non-Real Time metadata is broadcast in a service signaling channel as a part of the Service Map Table;
• where Non-Real Time content description text is stored in a Text Fragment Table, Non-Real Time content metadata is stored in the Non-Real Time Information Table, and the transport stream further comprises a Virtual Channel Table, where the Virtual Channel Table contains a service type code indicative of a virtual channel corresponding to Non-Real Time content;
• where the Non-Real Time Information Table includes entries in a Text Fragment Table and where the Non-Real Time Information Table includes a Playback Delay parameter that indicates an amount of time from the recovery of the first byte of a file containing the Non-Real Time content the receiver should wait prior to beginning playback of the content;
• and
• where the Non-Real Time Information Table points to a table that points to a graphical icon representation of the Non-Real Time service or content item.
