Abstract
A hierarchical broadcasting device and method are disclosed. In the hierarchical broadcasting method, a broadcast transmitting device may transmit lower layer broadcast data for an existing broadcast to a broadcast receiving device via a first communication network, and may transmit upper layer broadcast data for an improved broadcast to the broadcast receiving device via a second communication network. In this instance, the broadcast receiving device combines the lower layer broadcast data and the upper layer broadcast data in order to display the improved broadcast.
