    Abstract: Provided are an apparatus and method for multiplexing and demultiplexing based on DMB. The multiplexing apparatus includes a packetizer, a section generator, and a multiplexer. The packetizer (340) packetizes element streams and object information of a base layer and an enhancement layer. The section generator (350, 360) generates 14496 sections including the object information of the base layer and the enhancement layer, a SCST section having element stream information of the enhancement layer, an IOD having descriptors for the object information of the base layer and the enhancement layer, and a PSI section having a descriptor connecting the SCST. The multiplexer (380,390) generates base layer and enhancement layer TSs by multiplexing the packetized element streams and the packetized object information of the base layer and the enhancement layer, the 14496 sections including the object information of the base layer and the enhancement layer, the PSI section, and the SCST section.

    Abstract: A method and apparatus for processing enhanced media data in a Digital Multimedia Broadcasting (DMB) system is provided. The apparatus for processing enhanced media data includes: a base layer processing unit configured to multiplex an elementary stream of a base layer and perform channel encoding for the multiplexed elementary stream of the base layer; an enhancement layer processing unit configured to synchronize an elementary stream of an enhancement layer with the elementary stream of the base layer and thereby multiplex the elementary stream of the enhancement layer and process the elementary stream of the enhancement layer to be transmittable via at least one of a plurality of transmission channels; and a synchronizer configured to provide the enhancement layer processing unit with synchronization information that is used for synchronizing the elementary stream of the enhancement layer with the elementary stream of the base layer.
