Abstract

The present invention is directed to a system and method for viewer real-time access complementary information related to a broadcast program including selecting a plurality of topics drawing his or her attention and for accessing additional information related to these topics from the WWW. The system is based on a synchronization of the local times of receivers and transmitters according to a same universal-time. The synchronization uses a universal time such as the Global Positioning System Time, the Global Orbiting Navigational Satellite System time or others GPS or GLONASS receivers may be integrated or connected to devices independent or separate from the radio or television receivers. The system includes associated with the transmitted information and can be retrieved, selected and activated during the time intervals for which they have been defined.

Claims

1. A method of retrieving hyperlinks related to topics selected in a program broadcast on a channel, comprising:

identifying the channel that is broadcasting the program;

creating a universal-time table for the identified channel, the universal-time table comprising an identification of the channel, an address for accessing the information associated with the at least one hyperlink and/or a name designating the channel, being located at a receiver side on a user device;

receiving a selection command of a topic relating to a broadcast program by recording in the universal-time table a time corresponding to perception of said topic;

determining a universal time corresponding to receipt of the selection command, wherein the universal time is based on a universal timing system using a satellite based universal-time receiver;

obtaining from a server over a network, information associated with at least one hyperlink defined in the broadcast program and having a universal time interval associated therewith that corresponds to the universal time of receipt of the selection command, the universal time interval based on a synchronization of a local time and the universal timing system, wherein the information comprises a destination address within the network for accessing multimedia information, the universal time interval indicating when the destination address is active for access to the multimedia information;

storing the obtained destination address at the user device, wherein the local time is based on a location of the user device; and

accessing the multimedia information utilizing the at least one hyperlink from the destination address within the indicated universal time interval.

2. The method of claim 1, wherein determining a universal time further comprises recoding the determined universal in the universal-time table of the channel.

3. The method of claim 1, wherein obtaining from a server over a network further comprises retrieving the address for accessing the information associated with the at least one hyperlink from the universal-time table and obtaining the information utilizing the retrieved address.

4. The method of claim 1, further comprising storing the obtained destination address in the universal-time table.

5. The method of claim 1, wherein the user device and the server are synchronized according to the same universal time.

6. The method of claim 1, wherein the user device and a device receiving the program are separate devices.

7. The method of claim 1, wherein the at least one hyperlink comprises a plurality of hyperlinks and wherein accessing multimedia information comprises:

selecting a hyperlink from the plurality of hyperlinks; and

retrieving the multimedia information on a server connected to the network using an obtained destination address associated with the selected hyperlink.

8. The method of claim 7, wherein selecting a hyperlink comprises selecting a hyperlink from a universal-time table using a name, description and/or obtained destination address associated with the hyperlink.

9. The method of claim 7, further comprising displaying the retrieved multimedia information on the user device.

10. The method of claim 1, wherein the network comprises an Internet Protocol network, the server comprises a web server, the user device comprises a web browser and the destination address comprises a universal resource locator.

11. The method of claim 1 wherein the network comprises an Internet Protocol network, the server comprises a web server, the user device comprises a web browser, the destination address comprises a universal resource locator and the multimedia information comprises a web page.

12. The method of claim 1 wherein the multimedia information comprise one or more services.

13. The method of claim 1, wherein a universal-time receiver is integrated with the user device.

14. A system for retrieving hyperlinks related to topics selected in a program broadcast on a channel, comprising:

means for identifying the channel that is broadcasting the program;

means for creating a universal-time table for the identified channel, the universal-time table comprising an identification of the channel, an address for accessing the information associated with the at least one hyperlink and/or a name designating the channel, being located at a receiver side on a user device;

means for receiving a selection command of a topic relating to a broadcast program by recording in the universal-time table a time corresponding to perception of said topic;

means for determining a universal time corresponding to receipt of the selection command, wherein the universal time is based on a universal timing system using a satellite based universal-time receiver;

means for obtaining from a server over a network, information associated with at least one hyperlink defined in the broadcast program and having a universal time interval associated therewith that corresponds to the universal time of receipt of the selection command, the universal time interval based on a synchronization of a local time and the universal timing system, wherein the information comprises a destination address within the network for accessing multimedia information, the universal time interval indicating when the destination address is active for access to the multimedia information;

means for storing the obtained destination address at the user device, wherein the local time is based on a location of the user device; and

means for accessing the multimedia information utilizing the at least one hyperlink from the destination address within the indicated universal time interval.

15. A computer program product for retrieving hyperlinks related to topics selected in a program broadcast on a channel, comprising:

a computer readable storage medium having computer readable program code embodied therein, the computer readable program code comprising;

computer readable program code configured to identify the channel that is broadcasting the program;

computer readable program code configured to create a universal-time table for the identified channel, the universal-time table comprising an identification of the channel, an address for accessing the information associated with the at least one hyperlink and/or a name designating the channel, being located at a receiver side on a user device;

computer readable program code configured to receive a selection command of a topic relating to a broadcast program by recording in the universal-time table a time corresponding to perception of said topic;

computer readable program code configured to determine a universal time corresponding to receipt of the selection command, wherein the universal time is based on a universal timing system using a satellite based universal-time receiver;

computer readable program code configured to obtain from a server over a network, information associated with at least one hyperlink defined in the broadcast program and having a universal time interval associated therewith that corresponds to the universal time of receipt of the selection command, the universal time interval based on a synchronization of a local time and the universal timing system, wherein the information comprises a destination address within the network for accessing multimedia information, the universal time interval indicating when the destination address is active for access to the multimedia information;

computer readable program code configured to store the obtained destination address at the user device, wherein the local time is based on a location of the user device and

computer readable program code configured to access the multimedia information utilizing the at least one hyperlink from the destination address within the indicated universal time interval.
