摘要： A mobile communication system for providing a multicast/broadcast service is disclosed. The mobile communication systems comprise a base station that encodes video data of the mobile communication system into scalable bit streams and adaptively modulates and channel codes the scalable bit streams. A mobile communication terminal receives, demodulates and channel decodes the scalable bit streams transmitted from the base station and performs a process for scalable decoding the bit streams according to reception sensitivity. Overall system efficiency can be improved while increasing a transmission rate using scalable video coding according to channel characteristics between the mobile communication terminal and the base station in the multicast/broadcast service. Quality of service (QoS) can be provided based on the performance of the mobile communication terminal.
