摘要： A method and system for efficiently transmitting data, to which scalable image coding has been applied over a single frequency network is provided. The system includes a control server which re-packetizes data packets, received from a multimedia server, into a scalable bit stream by separately encoding the data packets into a base layer and one or more enhancement layers, and at least one base station which adaptively multicasts and broadcasts the scalable bit stream, received from the control server, to a plurality of terminals located in the area of a cell. The at least one base station multicasts and broadcasts the base layer across the area of the cell, and adaptively transmits the one or more enhancement layers depending on channel status or terminal performance of the plurality of terminals.
