Abstract

Techniques are described to transmit multimedia content to a mobile station using a combination of a mobile/cellular network as well as a TV Whitespace (TVWS) network. Scalable video coding can be used to transmit a baseline layer of multi-media content using the mobile/cellular network and one or more enhancement layers over the TVWS channels. Joint source-channel coding can be used to adjust the transmission scheme used by mobile/cellular and/or TVWS based on end user experience.
