System and method for pre-caching supplemental content related to a television broadcast using unprompted, context-sensitive querying

摘要

An interactive television system initiates unprompted, context-sensitive requests for supplemental content related to the television broadcast or discrete segments thereof. The related supplemental content is received by the interactive television system and pre-cached in a storage device associated therewith. In response to a user command, the stored supplemental content is retrieved and displayed by the interactive television system.
