Abstract

A method of indexing multimedia content by creating database records that include location data is disclosed. Devices that generate multimedia content also generate location data corresponding to the location of the device when the content is generated. The location data includes geographical coordinates such as latitude and longitude as well as orientation and tilt. Other data may be recorded such as date and time of day, and light exposure. The content and location data are communicated to a Content Index Processor (CIP) that creates a database record from the location data and determines classifications for the database record that can be used by a person that is searching for particular multimedia content.

Claims

1. A method comprising:

receiving multimedia content to be indexed and associated identification data, the multimedia content comprising audio and video;

extracting, from the identification data, location coordinates related to when a device generated the multimedia content;

creating a database record associated with the multimedia content and comprising a plurality of searchable location fields;

determining multiple, hierarchical classifications for the database record based on the location coordinates, the multiple hierarchical classifications for the database record comprising a hierarchy of geographic region designations associated with the location coordinates;

storing the database record with the multiple, hierarchical classifications, wherein each of the multiple, hierarchical classifications is used to populate a different one of the plurality of searchable location fields;

receiving, from a user, a request for content associated with a travel route, the request comprising a starting location, a destination location, a road selection, and a category of content;

identifying a threshold latitude distance and a threshold longitude distance;

retrieving, in response to the request and from the database record, a map of the travel route with the content, wherein the content is retrieved from the database by comparing the category of content to the searchable location fields and the multiple, hierarchical classifications, and wherein the content is within the threshold latitude distance and the threshold longitude distance of the travel route; and

presenting the map of the travel route with the content to the user.

2. The method of claim 1, wherein the location coordinates comprise a longitude coordinate and a latitude coordinate.

3. The method of claim 2, wherein the location coordinates comprise an orientation direction.

4. The method of claim 1, wherein the location coordinates comprise a tilt angle.

5. The method of claim 1, wherein the identification data further comprises a time of day at which the multimedia content was generated.

6. The method of claim 5, further comprising extracting from the identification data the time of day, wherein the step of creating further comprises creating a searchable field within the database record which comprises time of day, and wherein the step of determining further comprises using the time of day to determine the multiple, hierarchical classifications for the database record.

7. The method of claim 1, wherein the identification data further comprises a date on which the multimedia content was generated.

8. The method of claim 7, further comprising extracting from the identification data the date, wherein the step of creating further comprises creating a searchable field within the database record which comprises the date, and wherein the step of determining further comprises using the date to determine the multiple, hierarchical classifications for the database record.

9. The method of claim 1, wherein the multiple, hierarchical classifications comprises two of a country, a state, a province, and a city associated with the location coordinates.

10. The method of claim 9, wherein the multiple, hierarchical classifications further comprises a particular landmark associated with the location coordinates.

11. The method of claim 1, wherein the multimedia content further comprises an image.

12. The method of claim 1, wherein the database record comprises a description of the multimedia content.

13. The method of claim 1, further comprising providing user access to the databases via a web site.

14. The method of claim 13, wherein the web site comprises inputs for receiving search terms for searching the databases.

15. The method of claim 1, wherein determining multiple, hierarchical classifications for the database record further comprises selecting the hierarchy of geographic region designations by correlating the location coordinates with entries in a pre-defined classification table associating each of a plurality of pre-defined location coordinates with a pre-defined hierarchy of geographic region designations.

16. A system comprising:

a processor; and

a computer-readable storage medium having instructions stored which, when executed by the processor, cause the processor to perform operations comprising;

receiving multimedia content to be indexed and associated identification data, the multimedia content comprising audio and video;

extracting, from the identification data, location coordinates related to when a device generated the multimedia content;

creating a database record associated with the multimedia content and comprising a plurality of searchable location fields;

determining multiple, hierarchical classifications for the database record based on the location coordinates, the multiple hierarchical classifications for the database record comprising a hierarchy of geographic region designations associated with the location coordinates;

storing the database record with the multiple, hierarchical classifications, wherein each of the multiple, hierarchical classifications is used to populate a different one of the plurality of searchable location fields;

receiving, from a user, a request for content associated with a travel route, the request comprising a starting location, a destination location, a road selection, and a category of content;

identifying a threshold latitude distance and a threshold longitude distance;

retrieving, in response to the request and from the database record, a map of the travel route with the content, wherein the content is retrieved from the database by comparing the category of content to the searchable location fields and the multiple, hierarchical classifications, and wherein the content is within the threshold latitude distance and the threshold longitude distance of the travel route; and

presenting the map of the travel route with the content to the user.

17. A computer-readable storage device having instructions stored which, when executed by a computing device, cause the computing device to perform a method comprising:

receiving multimedia content to be indexed and associated identification data, the multimedia content comprising audio and video;

extracting, from the identification data, location coordinates related to when a device generated the multimedia content;

creating a database record associated with the multimedia content and comprising a plurality of searchable location fields;

determining multiple, hierarchical classifications for the database record based on the location coordinates, the multiple hierarchical classifications for the database record comprising a hierarchy of geographic region designations associated with the location coordinates;

storing the database record with the multiple, hierarchical classifications, wherein each of the multiple, hierarchical classifications is used to populate a different one of the plurality of searchable location fields;

receiving, from a user, a request for content associated with a travel route, the request comprising a starting location, a destination location, a road selection, and a category of content

identifying a threshold latitude distance and a threshold longitude distance;

retrieving, in response to the request and from the database record, a map of the travel route with the content, wherein the content is retrieved from the database by comparing the category of content to the searchable location fields and the multiple, hierarchical classifications, and wherein the content is within the threshold latitude distance and the threshold longitude distance of the travel route; and

presenting the map of the travel route with the content to the user.
