Patent ID: 8422564

Claim:
An apparatus for processing enhanced media data, the apparatus comprising: 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 transmitted over a plurality of types 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, wherein the elementary stream of the base layer is transmitted over a Terrestrial Digital Multimedia Broadcasting (T-DMB) transmission network after being output from the base layer processing unit and the elementary stream of the enhancement layer is transmitted over a non-T-DMB network after being output from the enhancement layer processing unit.
