Non-closed caption data transport in standard caption service
View Patent ↗Methods, apparatuses, and non-transitory computer-readable storage mediums for providing and/or processing non-closed caption data. The reception apparatus includes a receiver, a parser, and a processor. The receiver receives closed caption service data. The closed caption service data includes closed caption data within a first service block having a service number in the range of 1-6, and non-closed caption data within a second service block having a different service number in the range of 1-6. The closed caption data includes closed caption text. The parser parses the non-closed caption data within the second service block having the different service number in the range of 1-6. The processor performs a function based on the parsed non-closed caption data.

the non-closed caption data is carried in a CEA-708 compliant variable length command.
6. The reception apparatus according to claim 5 , wherein
the non-closed caption data is carried in the CEA-708 compliant variable length command having a variable length command of 0x98.
7. The reception apparatus according to claim 1 , wherein
the different service number of the second service block is service number 6.
8. The reception apparatus according to claim 1 , wherein
the circuitry is configured to receive audio/video (A/V) content associated with the closed caption service data, and
the non-closed caption data defines a trigger that identifies a location of data associated with the A/V content.
9. A method of a reception apparatus for processing non-closed caption data, the method comprising:
receiving, by circuitry of the reception apparatus, closed caption service data, the closed caption service data including closed caption data within a first service block having a service number in the range of 1-6, and non-closed caption data within a second service block having a different service number in the range of 1-6, the closed caption data including closed caption text;
parsing the non-closed caption data within the second service block having the different service number in the range of 1-6;
processing, by the circuitry, the non-closed caption data within the second service block irrespective of whether closed caption text from any service block included in the closed caption service data is to be processed for presentation to a user; and
performing, by the circuitry, a function based on the processed non-closed caption data.
10. The method according to claim 9 , wherein
the non-closed caption data defines a trigger that identifies a location of a trigger parameters table (TPT)), the TPT including metadata regarding a triggered declarative object (TDO) and at least one event associated with the TDO.
11. The method according to claim 9 , wherein
the non-closed caption data defines a trigger including information on a trigger type and a uniform resource identifier.
12. The method according to claim 9 , wherein
the non-closed caption data defines one or more parameters to be processed by a triggered declarative object (TDO).
13. The method according to claim 9 , wherein
the non-closed caption data is carried in a CEA-708 compliant variable length command.
14. The method according to claim 13 , wherein
the non-closed caption data is carried in the CEA-708 compliant variable length command having a variable length command of 0x98.
15. The method according to claim 9 , wherein
the different service number of the second service block is service number 6.
16. The method according to claim 9 , further comprising:
receiving audio/video (A/V) content associated with the closed caption service data, wherein
the non-closed caption data defines a trigger that identifies a location of data associated with the A/V content.
17. A non-transitory computer-readable storage medium storing instructions which when executed by a computer causes the computer to perform a method of a reception apparatus for processing non-closed caption data, the method comprising:
receiving, by the reception apparatus, closed caption service data, the closed caption service data including closed caption data within a first service block having a service number in the range of 1-6, and non-closed caption data within a second service block having a different service number in the range of 1-6, the closed caption data including closed caption text;
parsing the non-closed caption data within the second service block having the different service number in the range of 1-6;
processing, by the reception apparatus, the non-closed caption data within the second service block irrespective of whether closed caption text from any service block included in the closed caption service data is to be processed for presentation to a user; and
performing a function based on the parsed non-closed caption data.
18. An information providing apparatus, comprising:
circuitry configured to
generate or receive closed caption service data associated with audio/video (A/V) content; and
provide to a reception apparatus the A/V content and the closed caption service data, the closed caption service data including closed caption data within a first service block having a service number in the range of 1-6, and non-closed caption data within a second service block having a different service number in the range of 1-6, the closed caption data including closed caption text, wherein
the reception apparatus is configured to process the non-closed caption data within the second service block irrespective of whether closed caption text from any service block included in the closed caption service data is to be processed for presentation to a user.
