Abstract

Described are methods and apparatus for enhancing an information resource, such as a Web page, simultaneously residing in memory on a number of remote receivers. A content creator, (e.g., a program producer, broadcaster, affiliate, cable company or satellite provider), embeds a trigger in a data service channel of a broadcast signal. The trigger includes a resource identifier unique to the information resource and a script capable of modifying the information resource. The script might be a script or a segment of a script written in a conventional scripting language. Each receiver that includes the targeted information resource monitors the data service channel of the broadcast video signal for script-bearing triggers directed to that resource. If a receiver receives a script-bearing trigger directed to the resident resource, the receiver executes the script contained within the trigger to alter the resource and/or the displayed video defined by the resource.

Claims

1. A receiver for use in a method of enhancing an information resource comprising a Web page used to enhance a video broadcast signal with Internet content, wherein the information resource simultaneously resides in memory on a number of remote receivers, including said receiver, said receiver comprising:

a processor for processing computer-executable instructions stored in memory; and

memory having the computer-executable instructions stored thereon, wherein said computer executable instructions implement a method that includes;

a. storing, in one or more receivers, an information resource identified by a first resource identifier, the information resource including one or more scripts;

b. monitoring at the one or more receivers a data service channel of a broadcast signal for a script trigger, wherein the script trigger includes a second resource identifier and a script which contains executable code that passes a value to the one or more scripts of the information resource; and

c. thereafter, running the executable code of the script on the one or more receivers, upon receipt of the script trigger, if the second resource identifier matches the first resource identifier of the stored information resource.

2. The receiver of claim 1, wherein the method further comprises displaying the information resource stored in memory.

3. The receiver of claim 1, wherein the information resource comprises tags that define a context of the resource, and wherein the script modifies the context.

4. The receiver of claim 1, wherein the script is a fragment of a second script resident on the information resource.

5. The receiver of claim 1, wherein the method further comprises displaying a video portion of the broadcast signal, wherein the script trigger synchronizes the information resource with the video portion of the broadcast signal.

6. The receiver of claim 1, wherein the broadcast signal comprises video data, and wherein the script trigger induces an enhancement of the information resource.

7. The receiver of claim 1, wherein the first and second resource identifiers are URLs.

8. The receiver of claim 1, wherein the memory is RAM.
