<p>An aggregator, operating in a digital communications network, includes a request and results processing server, a search engine server coupled to the request and results processing server and a content acquisition server coupled to the request and results processing server. A request and results processing server receives a request for content, the search engine server searches for the content and the content acquisition program acquires content for delivery to the user. The request and results processing server includes a search request processor that receives infonuation related to a user's search request and provides the infonuation to a search results fonu builder that creates an electronic search request. The search request may be augmented by using a content suggestion engine to add additional search tenus and descriptions to the search request. The aggregator may also include a decoder that decodes program content and program metadata from remote sources for storage at the aggregator, and an encoder that encodes content metadata and programs for delivery to the user. The aggregator may also comprise one or more crawlers, such as a content crawler, to look for program content in one or more digital communications networks.</p> |
