Abstract
A broadcaster generates programming content and a carousel containing chunks of data defining one or more interactive applications. The programming content and carousel are received by a local gateway which distributes the carousel and content to receivers at end-users via a distribution network. A carousel proxy in the local gateway receives the inbound carousel from the broadcaster and modifies it to produce an outbound carousel suited for the distribution network, receivers, and/or end-users. The modifications performed by the carousel proxy include filtering chunks and/or data within the chunks from the inbound carousel and transforming data within the chunks to customize the interactive applications for the distribution network, receivers, and/or end-users. The carousel proxy also caches chunks in a cache of a local data store. The carousel proxy uses the cached chunks to send the outbound carousel at a rate optimized for the bandwidth available on the distribution network.
