Abstract

Described herein is a technology for in the realm of digital video broadcast technology or other such technology. One implementation, described herein, relates to broadcasting web content to client devices in a DVB (digital video broadcast) environment using rotational sequences of data modules (e.g., DSMCC carousels). One implementation, described herein, relates to emulating an interactive browsing experience of web content over a broadcast channel. One implementation, described herein, relates to the client device “smartly” caching select portions of the web content being broadcast. The scope of the present invention is pointed out in the appending claims.

a client device configured to receive such rotational sequences via the communications network;

wherein the client device is further configured to;

receive the one or more web assets in a digital video broadcast environment;

fetch the cache-control instructions from the one or more data modules, wherein the cache-control instructions;

help determine selected portions of the web assets to store and how long to temporarily store the selected portions of the web assets; and

include one or more hooks indicating specific web assets for caching;

cache the selected portions of the web assets based upon the instructions in anticipation of where a viewer may browse next; and

display the selected portions of the web assets.

3. A computer architecture as recited in claim 1, wherein the communications network is one-way.

4. A computer architecture as recited in claim 1, wherein the communications network is two-way, but a secondary channel is underutilized, slow, unreliable, or delayed compared to a primary channel.

5. A computer architecture as recited in claim 1, wherein the web content is selected from a group consisting of a markup language, HTML, and XML.

6. A computer architecture as recited in claim 1, wherein client device is further configured to receive digital video broadcasts.

7. A computer architecture as recited in claim 1, wherein client device is further configured to display portions of the web assets of the modules received via the communications network.

8. A broadcast-receiving client device comprising:

a processor;

a memory, coupled to the processor, storing computer-executable instructions;

a web browser application configured to render and display web content in a digital video broadcast environment;

an interface configured to receive one or more rotational sequences of data modules from a communications network, wherein one or more of the data modules comprise the web content;

a fetcher configured to fetch cache-control instructions from the one or more data modules and cache select portions of the web content based upon the cache-control instructions prior to a user browsing the web content, wherein the cache-control instructions;

are fetched in order to help determine selected portions of the web content to store and how long to temporarily store the selected portions of the web content; and

include one or more hooks indicating specific web content for caching;

a cache configured to store the selected portions of the web content based upon the cache-control instructions anticipating where a user browses; and

a user interface display configured to present the selected portions.

9. A device as recited in claim 8, wherein the rotational sequences are selected from a group consisting of DSMCC carousels, DSMCC data carousels, and DSMCC object carousels.

10. A device as recited in claim 8, wherein the communications network is one-way.

11. A device as recited in claim 8, wherein the communications network is two-way, but a secondary channel is underutilized, slow, unreliable, or delayed compared to a primary channel.

12. A device as recited in claim 8, wherein the web content is selected from a group consisting of a markup language, HTML, and XML.

13. A device as recited in claim 8 further comprising a receiving unit configured to receive digital video broadcasts.

14. A device as recited in claim 8 further comprising a display configured to present portions of the web content of the modules received via the communications network.
