Abstract: A method for performing a non-real-time stereoscopic service in a Terrestrial Digital Multimedia Broadcasting (T-DMB), and a T-DMB receiving apparatus are provided. The T-DMB receiving apparatus may store additional data in a nonvolatile storage device in advance, and may synchronize the stored additional data with reference data transmitted in real-time, to perform a stereoscopic service in a T-DMB service. The stereoscopic service may be performed without increasing transmission rate.

Abstract: The present invention relates to a channel encoder for an enhancement layer of a digital-multimedia-broadcasting transmitting device, a digital broadcasting transmitting device, a digital broadcasting receiving device, and an extension structure of sub-channel configuration field (FIG0/1 ) for designating a protection level of sub-channel at the enhancement layer. In a channel encoder for the enhancement layer according to the invention, the channel encoder is included in a hierarchical DMB transmitting unit that modulates a base layer transport stream and a enhancement layer transport stream for video and audio by a base layer modulation system and an enhancement layer modulation system, respectively, and performs symbol mapping of the enhancement layer according to the position of a constellation based on the base layer modulation system. Furthermore, the hierarchical DMB transmitting unit includes an energy dispersal scrambler that disperses energy of the enhancement layer transport stream, and a turbo encoder that receives a double-binary input vector corresponding to an output of the energy dispersal scrambler and encodes it by using a double-binary circular recursive systematic code.
