Abstract: Disclosed are a transmitter and a receiver for providing multi-layered multimedia services, and a method thereof. The transmitter for providing multimedia services includes a multiple description coding unit that performs multiple description coding (MDC) with respect to at least one source to thereby output a description sequence with respect to each of the at least one source, a description multiplexing unit that multiplexes the description sequence in units of descriptions to thereby output a single multiplexing description sequence, and a transmission code block processing unit that divides and modulates the single multiplexing description sequence to thereby generate a transmission block. Therefore, it is possible to provide high-quality multimedia services while ensuring graceful performance degradation and scalability.
