Abstract

An information processor includes a receiver configured to receive, from a first device, a response information request including content identification information for identifying a content in a network; an extraction portion configured to extract a plurality of element information pieces included in the content identification information; a storage to store therein each of conditions for a first element information piece among the plurality of element information pieces, and a response information piece in association with each other; and a generator configured to generate a response message including the response information piece stored in association with a condition that the first element information piece extracted by the extraction portion satisfies among the conditions for the first element information piece stored in the storage portion.

Claims

1. An information processor comprising:

a receiver configured to receive, from a first device, a response information request including content identification information for identifying a content in a network;

an extraction portion configured to extract a plurality of element information pieces included in the content identification information;

a storage to store therein each of conditions for a first element information piece among the plurality of element information pieces, and a response information piece in association with each other; and

a generator configured to generate a response message including the response information piece stored in association with a condition that the first element information piece extracted by the extraction portion satisfies among the conditions for the first element information piece stored in the storage portion.

2. The information processor according to claim 1, wherein the first element information piece is time information on the content.

3. The information processor according to claim 1, further comprising:

a second storage to store therein first conversion information for converting the element information pieces; and

a first conversion portion configured to convert the element information pieces by use of first information on the first device and the first conversion information.

4. The information processor according to claim 3, wherein the first information on the first device is information included in the response information request.

5. The information processor according to claim 1, further comprising:

a third storage to store therein second conversion information for converting the content identification information; and

a second conversion portion configured to convert the content identification information by use of second information on the first device and the second conversion information.

6. The information processor according to claim 5, wherein the second information on the first device is information included in the response information request.

7. The information processor according to claim 3, wherein:

the first conversion information is information in which the element information pieces included in the content identification information are associated with a combination of a broadcast area and a broadcaster, and the first information on the first device is a broadcast area to which the first device belongs; and

in a case where a broadcast area stored in association with the element information pieces extracted by the extraction portion is different from the broadcast area to which the first device belongs, the first conversion portion converts the element information pieces extracted by the extraction portion into element information pieces associated with a combination of the broadcast area to which the first device belongs and the broadcaster associated with the element information pieces extracted by the extraction portion.

8. The information processor according to claim 5, wherein:

the second conversion information is information in which the content identification information is associated with information on a medium providing the content, and the second information on the first device is information indicating a medium supported by the first device;

in a case where a medium providing a content identified by the content identification information included in the response information request is different from the medium supported by the first device, the second conversion portion converts the content identification information included in the response information request into content identification information stored in association with the medium supported by the first device; and

the generator generates a response message including the response information piece corresponding to the condition satisfied by the element information pieces converted by the conversion portion.

9. The information processor according to claim 1, further comprising a second extraction portion, wherein:

the response information request further includes device information on the first device;

the second extraction portion extracts the device information from the response information request;

the storage portion stores therein the response information piece in association with a combination of each of the conditions for the element information pieces and a condition for the device information; and

the generator generates a response message including a response information piece associated with the condition satisfied by the device information extracted by the second extraction portion.

10. The information processor according to claim 9, wherein the response message includes information to be displayed on the first device.

11. The information processor according to claim 10, wherein the response message includes a control command program which serves as user interface information, and which enables processing to be performed on the content corresponding to the response message.

12. The information processor according to claim 11, wherein the control command program varies depending on a type of execution device that actually performs the processing on the content.

13. The information processor according to claim 12, further comprising a content information storage to store therein content element information being information on the content;

and

the generator includes the content element information in the response message.

14. The information processor according to claim 13, further comprising a transmitter configured to transmit the response message generated by the generator to the first device.

15. The information processor according to claim 14, wherein in a case where the first device is different from an execution device that actually performs processing on the content, the generator includes control protocol information for controlling the execution device in the response message.

16. An information processing method comprising the steps of:

receiving, from a first device, a response information request including content identification information for identifying a content in a network;

extracting a plurality of element information pieces included in the content identification information; and

generating a response message with reference to a storage to store therein each of conditions for a first element information piece among the plurality of element information pieces and a response information piece in association with each other, the response message including the response information piece stored in association with the condition that the first element information piece extracted in the extraction step satisfies, among the conditions for the first element information piece stored in the storage portion.

17. The information processing method according to claim 16, wherein the first element information piece is time information on the content.

18. A computer readable medium storing an information processing program for causing a computer to generate a message, comprising the functions of:

receiving, from a first device, a response information request including content identification information for identifying a content in a network;

extracting a plurality of element information pieces included in the content identification information; and

generating a response message with reference to a storage to store therein each of conditions for a first element information piece among the plurality of element information pieces and a response information piece in association with each other, the response message including the response information piece stored in association with the condition that the first element information piece extracted by the extraction function satisfies, among the conditions for the first element information piece stored in the storage portion.

19. The computer readable medium storing the information processing program, according to claim 18, wherein the first element information piece is time information on the content.
