Patent ID: 8225367

Claim:
In a television entertainment infrastructure, a head-end server comprising: one or more processors; a memory; a data input component maintained in the memory and executed on the one or more processors to: identify an address corresponding to an external data source and source content, the source content being in an HTML data format; and download the source content from the external data source; and a conversion component maintained in the memory and executed on the one or more processors to: determine a structure of the source content based at least in part on a document object model, the structure of the source content being transcoded by extracting a location and a shape of hot-spots associated with the source content by searching the document object model for anchor tags and client-side image maps, the location and shape of the hot-spots being stored in metadata associated with the source content; automatically convert the structure of the source content into an interactive walled garden program (iWGP), the iWGP being a navigable page tree that includes multiple MPEG stills and metadata for navigating the MPEG stills, the iWGP for broadcast delivery to a client in the television entertainment infrastructure; and add multiple instances of a more frequently accessed MPEG still of the multiple MPEG stills to a transport carousel at predetermined spaced-apart locations, a priority assigned to the more frequently accessed MPEG still determining a frequency with which the more frequently accessed MPEG still appears in the transport carousel.
