3-dimensional digital multimedia broadcasting system

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.

Description

technical field [0001] The present invention relates to a three-dimensional digital multimedia broadcasting (3-dimensional Digital Multimedia Broadcasting, 3D DMB) system; in particular, to a 3D DMB transmission and reception system for transmitting 3D AV by encoding 3D audio / video (AV), and by encoding The received signal is decoded into 3DAV to provide a service to the user, so as to provide the user with a more realistic stereo broadcast while maintaining compatibility with the conventional DMB system. Background technique [0002] Due to the development of computer and communication technology, the field of communication between people has been significantly changed, and the traditional one-way service to actively use bidirectional services. [0003] The DMB system is a broadcasting system for providing various multimedia services such as video, audio, and data to mobile users anytime and anywhere, and services of the DMB system have been prepared in Korea for the first...
