Abstract (en)

[origin: WO2008136623A1] A transmission device and receiving device for providing high-quality multimedia services in a digital multimedia broadcasting (DMB) transmission system is provided. The transmission device separates input multimedia contents into a base layer elementary stream and an enhancement layer elementary stream, encodes the base layer elementary stream and the enhancement layer elementary stream, transforms the base layer elementary stream and the enhancement layer elementary stream into a base layer SL packet and an enhancement layer SL packet, transforms the base layer SL packet and the enhancement layer SL packet into a base layer PES packet and an enhancement layer PES packet, and multiplexes the base layer PES packet and the enhancement layer PES packet according to a base layer elementary stream and an enhancement layer elementary stream and outputs a base layer TS packet and an enhancement layer TS packet.
