An efficient hybrid delivery technology for a broadcast TV service

Increasing popularization of mobile devices has pushed emergence of new services and technologies with convergence of broadcasting and broadband. One of the most striking issues of hybrid broadcasting is synchronization of delivered data over a heterogeneous network. Therefore, we consider a method of synchronization for delivery of hybrid content, as well as between devices using different service platforms. A hybrid delivery architecture and synchronization algorithm for heterogeneous networks in an inter-device environment is developed. In an inter-device system with broadcasting and broadband networks, experimental results verify that the proposed algorithm achieves accurate synchronization performance.
