Abstract

An information processing apparatus includes a reception section that receives marking information from a different information processing apparatus and corresponding to a scene of a broadcast program. The marking information indicates a broadcast station and a broadcast time. The information processing apparatus also includes a processing unit that extracts a Universal Resource Identifier (URI) based on the broadcast station and the broadcast time, and produces navigation information associated with the scene of the broadcast program, based on the URI.

Claims

1. An information processing apparatus, comprising:

a reception section that receives marking information from a different information processing apparatus and corresponding to a scene of a broadcast program, the marking information indicating a broadcast station and a broadcast time; and

a processing unit configured to extract a Universal Resource Identifier (URI) based on the broadcast station and the broadcast time, and to produce navigation information associated with the scene of the broadcast program, based on the URI, wherein the navigation information defines a latitude.

2. The information processing apparatus according to claim 1, wherein the processing unit accesses a server designated by the URI to download data, the processing unit further configured to extract information representative of a position from the data and to read out the latitude based on the position.

3. The information processing apparatus according to claim 2, wherein the processing unit searches the data for a keyword and extracts a character string adjacent to the keyword to extract the information representative of the position.

4. The information processing apparatus according to claim 3, wherein the processing unit reads out the latitude based on the character string to produce position information.

5. The information processing apparatus according to claim 4, wherein the processing unit produces the navigation information based on the position information.

6. The information processing apparatus according to claim 3, wherein the keyword indicates a telephone number, and the character string follows the keyword.

7. The information processing apparatus according to claim 2, wherein the data defines a geographical address.

8. The information processing apparatus according to claim 1, wherein the navigation information is based on basic navigation information including route information for guiding a route followed by the broadcast program from a starting point to an ending point through a plurality of branches.

9. The information processing apparatus according to claim 8, wherein the reception section receives information of a restriction condition, and the processing unit executes a filtering process of the basic navigation information based on the restriction condition to produce the navigation information.

10. The information processing apparatus according to claim 9, wherein the processing unit performs the filtering process by determining whether a point of the route information satisfies the restriction condition and by not including the point in the navigation information in response to a determination that the point does not satisfy the restriction condition.

11. The information processing apparatus according to claim 9, wherein the processing unit performs the filtering process by determining whether a point of the route information satisfies the restriction condition, and the processing unit registers the point in the navigation information in response to a determination that the point does satisfy the restriction condition.

12. The information processing apparatus according to claim 8, wherein the processing unit is configured to perform a history information process to produce the navigation information by determining whether a point of the navigation information is within a predetermined distance from a history point produced in the past.

13. The information processing apparatus according to claim 12, wherein the processing unit performs the history information process by including the history point in the navigation information in response to a determination that the point of the navigation information is within the predetermined distance from the history point.

14. The information processing apparatus according to claim 8, wherein the processing unit is configured to determine whether a shop exists within a predetermined distance from a point in the navigation information and to include a point of the shop in the navigation information in response to a determination that the shop exists within the predetermined distance from the point in the navigation information.

15. The information processing apparatus according to claim 1, further comprising:

a transmission section that transmits the navigation information to the different information processing apparatus.

16. The information processing apparatus according to claim 1, wherein the URI is multiplexed in a broadcast signal when the scene was broadcast.

17. The information processing apparatus according to claim 1, wherein the processing unit records information of points included in the navigation information into a memory.

18. An information processing method for an information processing apparatus, the information processing method comprising:

receiving marking information from a different information processing apparatus and corresponding to a scene of a broadcast program, the marking information indicating a broadcast station and a broadcast time;

extracting, with the information processing apparatus, a Universal Resource Identifier (URI) based on the broadcast station and the broadcast time; and

producing, with the information processing apparatus, navigation information associated with the scene of the broadcast program, based on the URI, wherein the navigation information defines a latitude.

19. A recording medium on which a computer-readable program for an information processing apparatus is recorded, the program for causing a computer to execute a method comprising:

receiving marking information from a different information processing apparatus and corresponding to a scene of a broadcast program, the marking information indicating a broadcast station and a broadcast time;

extracting a Universal Resource Identifier (URI) based on the broadcast station and the broadcast time; and

producing navigation information associated with the scene of the broadcast program, based on the URI, wherein the navigation information defines a latitude.
