Abstract

An interconnected architecture for set-top boxes (STBs) configured to facilitate media streaming in a network environment. In one embodiment, a data center associated with the network environment includes a control plane manager operative to receive and process media requests from a plurality of subscriber devices, each subscriber device comprising at least a media renderer and a user interface operative with a virtual STB hosted at the data center. One or more vSTBs associated with a plurality of subscribers may be hosted at the data center, which may be logically organized into a number of mesh architectures. The control plane manager is further operative to determine if a request from a subscriber device for a particular content is for content that already exists at one or more vSTBs hosted in the data center, and if so, select an optimal vSTB that already supports a stream of the requested particular content for effectuating a media session with the subscriber device.
