摘要： 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.

摘要： A method for processing a digital audio broadcast signal includes: separating an analog audio portion and a digital audio portion of the digital audio broadcast signal; determining the loudness of the analog audio portion and the digital audio portion over a first short time interval; using the loudness of the analog and digital audio portions to calculate a short term average gain; determining a long term average gain; converting one of the long term average gain or the short term average gain to dB; if an output has been blended to digital, adjusting a digital gain parameter by a preselected increment to produce a digital gain parameter; if an output has not been blended to digital, setting the digital gain parameter to the short term average gain; providing the digital gain parameter to an audio processor; and repeating the above steps using a second short time interval.

摘要： A method for controlling the peak levels of an FM composite signal is described. First, the FM signal is clipped to obtain an error signal (10). This signal comprises the "clippings" resulting from the clipping operation. Next, the peaks of the error signal are determined (12). Then, a half-cosine wave is fitted to each of the peaks (14). The resultant half-cosine-interpolated signal is filtered to provide a filtered error signal (16) and the filtered error signal is subtracted from the FM composite signal (18).
