Abstract

A digital broadcast signal is received to a digital television receiver in a computer. The digital broadcast signal is processed to extract enhanced content data. The enhanced content data is stored in a web browser cache. The web browser cache is interrogated with an application programming interface. Responsive to the application programming interface interrogating the web browser cache, the enhanced content data is provided to a personal web server. The enhanced content data in the personal web server is stored and providing to at least one client device.

Claims

1. A method comprising:

receiving a digital broadcast signal to a digital television receiver in a first computer, wherein the digital broadcast signal includes content and enhanced content data, and wherein the enhanced content data includes triggers and announcements to synchronize the digital broadcast signal content with content on a display;

processing the digital broadcast signal to extract the enhanced content data;

storing the enhanced content data in a web browser cache;

interrogating the web browser cache with an application programming interface;

providing the enhanced content data to a personal web server responsive to the application programming interface interrogating the web browser cache;

storing the enhanced content data in the personal web server; and

providing the enhanced content data stored in the personal web server to a client device via a personal web page hosted by the personal web server, wherein the personal web page is a home page for the personal web server, comprising;

loading the personal web page on the client device, wherein a synchronization client is created as an object window in the personal web page on the client device; and

updating the object window via the synchronization client when enhanced content data is received from a synchronization server in the first computer.

2. The method of claim 1 further comprising:

extracting content triggers from the enhanced content data; and

providing the content triggers to the synchronization client through a network.

3. The method of claim 2 wherein the personal web server is simultaneously providing enhanced content data stored in the personal web server to a plurality of client devices and the synchronization server is providing content triggers to at least one synchronization client.

4. The method of claim 3 wherein the client device is receiving the triggers wherein the content triggers update the synchronization client to be displaying information synchronized to the digital broadcast signal on the client device.

5. The method of claim 4 wherein the synchronization server is providing triggers to a network connection by multicasting datagram packets to sockets using a transmission protocol.

6. The method of claim 5 wherein the synchronization client is receiving the datagram packets provided by the synchronization server though a network connection.

7. The method of claim 1 wherein the client device is a second computer.

8. The method of claim 1 wherein the client device is an interactive tablet.

9. The method of claim 1 wherein the client device is a personal digital assistant.

10. A product, the product comprising:

instructions to direct a first processor to

receive a digital broadcast signal to a digital television receiver in a first computer, wherein the digital broadcast signal includes content and enhanced content data, and wherein the enhanced content data includes triggers and announcements to synchronize the digital broadcast signal content with content on a display,

process the digital broadcast signal to extract the enhanced content data,

store the enhanced content data in a web browser cache,

interrogate the web browser cache with an application programming interface from a personal web server,

provide the enhanced content data to the personal web server responsive to the application programming interface interrogating the web browser cache,

store the enhanced content data in the personal web server, and

provide the enhanced content data stored in the personal web server to a client device via a personal web page hosted by the personal web server, wherein the personal web rage is a home page for the personal web server, wherein the personal web page is loaded on the client device, wherein a synchronization client is created as an object window in the personal web page on the client device and wherein the object window is updated via the synchronization client when enhanced content data is received from a synchronization server in the first computer, and;

computer-readable medium to store the instructions.

11. The product of claim 10 further comprising:

instructions to direct the first processor to;

extract content triggers from the enhanced content data, and

provide the content triggers to the synchronization client, and;

computer-readable medium to store the instructions.

12. The product of claim 11 wherein the instructions direct a personal web server to provide enhanced content data stored in the personal web server to a plurality of client devices while the synchronization server is simultaneously providing content triggers to at least one synchronization client.

13. The product of claim 12 wherein the client device is receiving the content triggers wherein the content triggers update the synchronization client to be displaying information synchronized to the digital broadcast signal on the client device.

14. The product of claim 13 wherein the synchronization server is providing content triggers to a network connection by multicasting datagram packets to sockets using a transmission protocol.

15. The product of claim 14 wherein the synchronization client is receiving the datagram packets provided by the synchronization server though a network connection.

16. The product of claim 10 wherein the client device is a second computer.

17. The product of claim 10 wherein the client device is an interactive tablet.

18. The product of claim 10 wherein the client device is a personal digital assistant.

19. The product of claim 10 wherein the client device is a remote control device with a display panel.

instructions to direct a processor to;

receive a digital broadcast signal to a digital television receiver in a first computer, wherein the digital broadcast signal includes content and enhanced content data, and wherein the enhanced content data includes triggers and announcements to synchronize the digital broadcast signal content with content on a display, process the digital broadcast signal to extract the enhanced content data, store the enhanced content data in a web browser cache, interrogate the web browser cache with an application programming interface from a personal web server, provide the enhanced content data to the personal web server responsive to the API interrogating the web browser cache, store the enhanced content data in the personal web server, and provide the enhanced content stored in the personal web server to the client device via a personal web page hosted by the personal web server, wherein the personal web page is a home page for the personal web server, wherein the personal web page is loaded on the client device, wherein a synchronization client is created as an object window in the personal web page on the client device and wherein the object window is updated via the synchronization client when enhanced content data is received from a synchronization server in the first computer, and;

machine readable media to store the instructions.

21. The system of claim 20 wherein the instructions to direct a processor further include instructions to:

extract content triggers from the enhanced content data,

provide the content triggers to the synchronization client, and;

machine readable media to store the instructions.

22. The system of claim 21 wherein the instructions direct a personal web server to provide enhanced content data stored in the personal web server to a plurality of client devices while the synchronization server is simultaneously providing the content triggers to at least one synchronization client.
