Non-real time services
View Patent ↗In certain embodiments, a digital television receiving method that receives non-real time (NRT) content involves receiving a transport stream containing an Internet Protocol (IP) stream of packets containing non-real time content, NRT service metadata and NRT content metadata; at a demultiplexer, demultiplexing the IP stream of packets to produce: NRT content that is stored in the electronic storage medium, NRT service metadata, and NRT content metadata; parsing the NRT metadata to produce NRT service metadata, and NRT content metadata; and where the NRT content metadata contains a signal that indicates that an update is available indicating whether or not a referenced content item will be updated periodically. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
1. A digital television receiver that receives Non-Real Time content, comprising in combination:
a radio frequency tuner that receives a radio frequency modulated channel containing a transport stream and demodulates the channel to produce an output transport stream;
the output transport stream containing an Internet Protocol stream of packets containing Non-Real Time content, Non-Real Time service metadata and Non-Real Time content metadata;
an electronic storage medium;
a demultiplexer that demultiplexes the Internet Protocol stream of packets to produce:
Non-Real Time content that is stored in an electronic storage medium,
Non-Real Time service metadata, and
Non-Real Time content metadata;
a Non-Real Time metadata parser that produces Non-Real Time service metadata, and Non-Real Time content metadata; and
where the Non-Real Time content metadata contains a signal that indicates that an update is available indicating whether or not a referenced content item will be updated periodically.
2. The digital television receiver according to claim 1 , wherein the update available signal is received within a Non-Real Time Information Table.
3. A digital television receiver that receives Non-Real Time content, comprising in combination:
an Internet Protocol receiver that receives a stream of Internet Protocol packets and selects an Internet Protocol subnet containing a packet stream selected as an output packet stream;
the output packet stream containing Non-Real Time content, Non-Real Time service metadata and Non-Real Time content metadata;
an electronic storage medium;
a demultiplexer that demultiplexes the Internet Protocol packet stream to produce:
Non-Real Time content that is stored in the electronic storage medium,
Non-Real Time service metadata, and
Non-Real Time content metadata;
an Non-Real Time metadata parser that produces Non-Real Time service metadata and Non-Real Time content metadata; and
where the Non-Real Time content metadata contains a signal that indicates that an update is available signal indicating whether or not a referenced content item will be updated periodically.
4. The digital television receiver according to claim 3 , wherein the update available signal is received within a Non-Real Time Information Table.
5. A digital television receiver that receives Non-Real Time 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 stream of packets containing Non-Real Time content, a FLUTE File Description Table, Non-Real Time service and Non-Real Time content metadata;
an electronic storage medium;
a demultiplexer that demultiplexes the Internet Protocol stream of packets to produce:
Non-Real Time content that is stored in the electronic storage medium, the FLUTE File Description Table,
Non-Real Time service metadata, and
Non-Real Time content metadata;
a File Description Table parser that parses the File Description Table to produce Non-Real Time file metadata from the FLUTE File Description Table;
a Non-Real Time metadata parser that produces Non-Real Time service metadata, Non-Real Time content description text and Non-Real Time content metadata;
wherein the Non-Real Time content metadata is received within a Non-Real Time Information Table; and
where the Non-Real Time content metadata contains a signal indicating that an update is available and indicating whether or not a referenced content item will be updated periodically.
6. A digital television receiving method that receives Non-Real Time content, comprising:
receiving a transport stream containing an Internet Protocol stream of packets containing Non-Real Time, Non-Real Time service metadata and Non-Real Time content metadata;
at a demultiplexer demultiplexing the Internet Protocol stream of packets to produce:
Non-Real Time content that is stored in an electronic storage medium,
Non-Real Time service metadata, and
Non-Real Time content metadata;
parsing the Non-Real Time metadata to produce Non-Real Time service metadata, and Non-Real Time content metadata; and
where the Non-Real Time content metadata contains a signal that indicates that an update is available and indicating whether or not a referenced content item will be updated periodically.
7. The digital television receiver method according to claim 6 , wherein the update available signal is received within a Non-Real Time Information Table.
