Non-real time services
View Patent ↗In certain embodiments, a digital television receiver method for receiving 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; a demultiplexer that demultiplexes the IP stream of packets to produce: NRT content, NRT service metadata, and NRT content metadata; an NRT metadata parser that produces NRT service metadata and NRT content metadata; and where the NRT service metadata contains an indication whether or not a particular NRT service is to be offered on a subscription basis. 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 the 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 service metadata contains an indication whether or not a particular Non-Real Time service is to be offered on a subscription basis.
2. The digital television receiver according to claim 1 , wherein an offering of subscription-based content is identified within the delivered Non-Real Time service metadata.
3. The digital television receiver according to claim 1 , wherein the indication of subscription-based content within the Non-Real Time service is received within a Service Map Table.
4. 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;
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 service metadata contains an indication whether or not a particular Non-Real Time service is to be offered on a subscription basis.
5. The digital television receiver according to claim 4 , wherein an offering of subscription-based content is identified within the delivered Non-Real Time service metadata.
6. The digital television receiver according to claim 4 , wherein the indication of subscription-based content within the Non-Real Time service is received within a Service Map Table.
7. 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 NRT content metadata,
wherein the Non-Real Time content metadata is received within a Non-Real Time Information Table; and
where the Non-Real Time service metadata contains an indication whether or not a particular Non-Real Time service is to be offered on a subscription basis.
8. A digital television receiver method for receiving Non-Real Time content, comprising:
receiving a 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;
a demultiplexer that demultiplexes the Internet Protocol stream of packets to produce:
Non-Real Time content,
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 service metadata contains an indication whether or not a particular Non-Real Time service is to be offered on a subscription basis.
9. The digital television receiver method according to claim 8 , wherein an offering of subscription-based content is identified within the delivered Non-Real Time service metadata.
10. The digital television receiver method according to claim 8 further comprising storing the Non-Real Time content to an electronic storage medium.
11. The digital television receiver method according to claim 8 , wherein the indication of subscription-based content within the Non-Real Time service is received within a Service Map Table.
