Abstract: Provided is a method for providing a DMB-based 3D stereoscopic image service using an MPEG-4 object descriptor of a new structure to provide users with a realistic 3D image service while maintaining compatibility to a conventional DMB system, and a decoding apparatus and method for the DMB-based 3D stereoscopic image service. The method includes the steps of: a) defining in a data service component type that a broadcast service is a DMB service, and defining a dimension of the DMB service in a user application type; and b) assigning a reference image and 3D additional information for a serviced 3D image as different streams which are independent from each other by using different object descriptors.

Abstract: Provided is an object description and multiplexing method which provides an object descriptor of a new structure and a multiplexing method for a 3D still image service based on DMB, such as 3D still image advertisement service, and provides 3D a user with still image service through interaction with the user at a specific time or specific video scene while maintaining compatibility with conventional DMB services, and a decoding apparatus and method using the object description and multiplexing method. The method for describing an object to provide a 3D still image service based on DMB, which includes: deciding a broadcasting type of a still image service to be broadcasted between two-dimensional broadcasting and 3D broadcasting based on a program information descriptor in a program map table; and describing reference still image and additional still image that are transmitted separately for the 3D still image service with relation to each other.

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.
