摘要： Systems and methods presented herein provide for a software defined network (SDN) controller in a cable television system that virtualizes network elements in the cable television system to provide content delivery and data services through the virtualized network elements. In one embodiment, the SDN controller is operable in a cloud computing environment to balance data traffic through the virtualized network elements. For example, the SDN controller may process a request for content from a user equipment (UE), determine a bandwidth capability of the UE, determine that bandwidth of the requested content exceeds the bandwidth capability of the UE, analyze the bandwidth capacity of the network elements, generate a virtual channel through the network elements based on the bandwidth capacity of the network elements, and to deliver the content to the UE through the virtualized channel.

摘要： A distribution system and reception apparatus, and methods thereof, are provided for broadcasting and receiving a plurality of non-backwards-compatible services. The broadcasting method includes receiving, by a first service provider, a plurality of first services, which include a first service from each of the first and second service providers. The first service provider generates a first broadcast multiplex, including the plurality of first services, and broadcasts the first broadcast multiplex on a first broadcast channel allocated to the first service provider. A second service provider receives a plurality of second services, which include a second service from each of the first and second service providers. The second service provider generates a second broadcast multiplex, including the plurality of second services, and broadcasts the second broadcast multiplex on a second broadcast channel allocated to the second service provider.
