The rapidly increasing power of personal mobile devices (Smartphones, tablets, etc.) is providing much richer contents and social interactions to users on the move. The recent cloud computing technology, with its rich resources to compensate for the limitations of mobile devices and connections, can potentially provide an ideal platform to support the desired mobile services. Tough challenges arise on how to effectively exploit cloud resources to facilitate mobile services, especially those with stringent interaction delay requirements. This system is based on the design of a Cloud-based, novel Mobile social tV system (CloudMoV).
