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 a method for simply generating counter block values without additionally transmitting the counter block values. The method for generating a counter block value required by a scrambler or a descrambler includes the steps of : a) setting up a counter of a message to a predetermined initial value, when a counter block to be scrambled or descrambled is in an initial part of the message; b) storing a Common Interleaved Frame (CIF) count value corresponding to the initial part of the message in a buffer, when the counter block to be scrambled or descrambled is in the initial part of the message; c) increasing the counter by a predetermined number; and d) generating the counter block value by using the CIF count value stored in the step b) and the counter increased in the step c).
