Non-real time services
View Patent ↗In certain embodiments, a method for receiving non-real time content involves 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; demultiplexing the Internet Protocol stream of packets to produce: non-real time content, non-real time service metadata, and non-real time content metadata. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
1. A 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.
2. The receiver according to claim 1 , where the Non-Real Time service metadata contains an indication whether or not a particular Non-Real Time service is subscription based.
3. The receiver according to claim 2 , where the indication of whether or not the particular Non-Real Time service is subscription based is within the delivered Non-Real Time service metadata.
4. The receiver according to claim 2 , where the indication of subscription-based content within the Non-Real Time service is received within a Service Map Table.
5. The receiver according to claim 1 , further comprising a Non-Real Time metadata parser that produces Non-Real Time service metadata and Non-Real Time content metadata.
6. A 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.
7. The receiver according to claim 6 , where the Non-Real Time service metadata contains an indication whether or not a particular Non-Real Time service is subscription based.
8. The receiver according to claim 7 , where the indication that the particular Non-Real Time service is or is not subscription-based is delivered as Non-Real Time service metadata.
9. The receiver according to claim 7 , where the indication that the particular Non-Real Time service is or is not subscription-based is received within a Service Map Table.
10. The receiver according to claim 6 , further comprising a Non-Real Time metadata parser that produces Non-Real Time service metadata and Non-Real Time content metadata.
11. A 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 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 File Description Table,
Non-Real Time service metadata, and
Non-Real Time content metadata.
12. The receiver according to claim 11 , where the File Description Table comprises a FLUTE file description table.
13. The receiver according to claim 11 , further comprising a File Description Table parser that parses the File Description Table to produce Non-Real Time file metadata from the File Description Table.
14. The receiver according to claim 11 , further comprising 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.
15. The receiver according to claim 11 , where the Non-Real Time content metadata is received within a Non-Real Time information table.
16. The receiver according to claim 11 , where the Non-Real Time service metadata contains an indication of whether or not a particular Non-Real Time service is subscription based.
17. A 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;
demultiplexing the Internet Protocol stream of packets to produce:
Non-Real Time content,
Non-Real Time service metadata, and
Non-Real Time content metadata.
18. The method according to claim 17 , further comprising parsing the Non-Real Time metadata to produce Non-Real Time service metadata and Non-Real Time content metadata.
19. The method according to claim 17 , where the service metadata contains an indication whether or not a particular Non-Real Time service is subscription based.
20. The method according to claim 17 , where the Non-Real Time service metadata contains an indication of whether or not a particular Non-Real Time service is subscription-based.
21. The method according to claim 17 , further comprising storing the Non-Real Time content to an electronic storage medium.
22. The method according to claim 17 , where a Service Map Table contains an indication of whether or not a particular Non-Real Time service is subscription-based.
