Abstract

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.

Claims

1. A reception apparatus, comprising:

a receiver configured to receive a digital television signal including a caption data stream and a closed caption service descriptor that identifies a first Standard caption service that includes first closed caption text; and

processing circuitry configured to

extract non-closed caption data from a second Standard caption service, which is different from the first Standard caption service and has a number representative of an adjunct data channel of the caption data stream, irrespective of whether the second Standard caption service having the number representative of the adjunct data channel is identified in the closed caption service descriptor as including second closed caption text;

process the extracted non-closed caption data; and

process the second closed caption text when the closed caption service descriptor indicates that the second closed caption text is included in the second Standard caption service and the second closed caption text is selected for display.

2. The reception apparatus according to claim 1, wherein

the non-closed caption data is carried in a CEA-708 compliant variable length command having a variable length command of 0x98.

3. The reception apparatus according to claim 1, wherein

the non-closed caption data includes location information, and

the processing circuitry is configured to download information from a server based on the location information.

4. The reception apparatus according to claim 3, wherein

the location information is a URI (Uniform Resource Identifier), and

the processing circuitry is configured to control execution of an application based on the URI.

5. The reception apparatus according to claim 3, wherein

the location information is a URI (Uniform Resource Identifier) that includes a domain name part and a directory path.

6. The reception apparatus according to claim 3, wherein

the processing circuitry is configured to extract a plurality of control information from the second Standard caption service having the number representative of the adjunct data channel of the caption data stream,

the location information is a URI (Uniform Resource Identifier), and

each of the control information includes the same URI and a different event identifier.

7. The reception apparatus according to claim 3, wherein the processing circuitry is configured to extract non-closed caption data only from the second Standard caption service of one particular number.

8. The reception apparatus according to claim 3, wherein the second Standard caption service is Standard Service #6.

9. The reception apparatus according to claim 1, wherein

the closed caption service descriptor is a PSIP (Program and System Information Protocol) caption service descriptor.

10. The reception apparatus according to claim 1, wherein

the second Standard caption service having the number representative of the adjunct data channel is not identified in the closed caption service descriptor when the second closed caption text is not associated with the second Standard caption service having the number representative of the adjunct data channel, and

the second Standard caption service having the number representative of the adjunct data channel is identified in the closed caption service descriptor when the second closed caption text is associated with the second Standard caption service having the number representative of the adjunct data channel.

11. A television comprising the reception apparatus according to claim 1.

12. The reception apparatus according to claim 1, wherein the second Standard caption service having the number representative of the adjunct data channel is identified in the closed caption service descriptor based on whether the second Standard caption service having the number representative of the adjunct data channel includes the second closed caption text.

13. A method for performing a process, the method comprising:

receiving, by circuitry of a reception apparatus, a digital television signal including a caption data stream and a closed caption service descriptor that identifies a first Standard caption service that includes first closed caption text;

extracting, by the circuitry, non-closed caption data from a second Standard caption service, which is different from the first Standard caption service and has a number representative of an adjunct data channel of the caption data stream, irrespective of whether the second Standard caption service having the number representative of the adjunct data channel is identified in the closed caption service descriptor as including second closed caption text;

processing, by the circuitry, the extracted non-closed caption data; and

processing the second closed caption text when the closed caption service descriptor indicates that the second closed caption text is included in the second Standard caption service and the second closed caption text is selected for display.

14. The method according to claim 13, wherein

the non-closed caption data is carried in a CEA-708 compliant variable length command having a variable length command of 0x98.

15. The method according to claim 13, wherein

the non-closed caption data includes location information, and

the method further comprises downloading information from a server based on the location information.

16. The method according to claim 15, wherein

the location information is a URI (Uniform Resource Identifier), and

the method further comprises controlling execution of an application based on the URI.

17. The method according to claim 15, wherein the location information is a URI (Uniform Resource Identifier) that includes a domain name part and a directory path.

18. The method according to claim 15, further comprising:

extracting a plurality of control information from the second Standard caption service having the number representative of the adjunct data channel of the caption data stream, wherein

the location information is a URI (Uniform Resource Identifier), and

each of the control information includes the same URI and a different event identifier.

19. The method according to claim 13, wherein

the closed caption service descriptor is a PSIP (Program and System Information Protocol) caption service descriptor.

20. A non-transitory computer-readable medium storing a program which when executed by a computer causes the computer to perform a method for performing a process, the method comprising:

receiving a digital television signal including a caption data stream and a closed caption descriptor that identifies a first Standard caption service that includes first closed caption text;

extracting non-closed caption data from a second Standard caption service, which is different from the first Standard caption service and has a number representative of an adjunct data channel of the caption data stream, irrespective of whether the second Standard caption service having the number representative of the adjunct data channel is identified in the closed caption service descriptor as including second closed caption text;

processing the extracted non-closed caption data; and

processing the second closed caption text when the closed caption service descriptor indicates that the second closed caption text is included in the second Standard caption service and the second closed caption text is selected for display.
