Abstract: Provide is a 3-dimensional Digital Multimedia Broadcasting (3D DMB) system. The present invention can provide a 3D DMB system providing a more realistic 3D Audio/Video (AV) service to a user, while maintaining comparability with a conventional DMB system, by processing a binocular 3D image and 3D sound based on a conventional system structure. The 3D DMB system includes: a video encoder for receiving and encoding a video signal of a binocular 3D image; an audio encoder for receiving and encoding an audio signal of a 3D sound; a packetizor for packetizing the encoded video and audio signals into an Sync Layer (SL) packet; and a multiplexer for transforming and multiplexing the SL packet packetized by the packetizer. A 3D DMB receiving system includes: a demultiplexer for demultiplexing a stream including binocular 3D image information and 3D sound information; a depacketizer for depacketizing the SL packet and outputting a decoding stream of an 3D video signal and a 3D sound audio signal; a video decoder for decoding a encoding stream for a video signal of the binocular 3D image; an audio decoder for decoding a encoding stream for the 3D sound audio signal; and a scene restorer for forming and outputting a 2D AV or 3D AV scene by using a video/3D additional video and an audio/3D additional audio signal which are received from the video decoder and the audio decoder.

Abstract: Provided is an apparatus and method for estimating inverse channel of a repeater's receiving channel, which ensures stability and causality by generating a time-domain filter coefficient having information on an inverse channel of repeater's receiving channel from a signal transmitted from a main transmitter or another repeater. The apparatus includes: a channel estimator for estimating a channel established by a transmission path from a received signal; an inverse minimum phase filter coefficient generator for generating inverse channel of a minimum phase channel from the estimated channel, and converting the inverse channel of the minimum phase channel into a time-domain filter coefficient; an inverse group delay filter coefficient generator for generating a time-domain filter coefficient by using the estimated channel and the minimum phase channel; and a combiner for generating an inverse channel of a receiving channel in a time domain by combining the filter coefficient and the filter coefficient.
