Abstract: Disclosed are systems and methods for generating and embedding scene processing information in a multimedia source. Scene processing information is generated based on an analysis of audio, video and data properties of the multimedia source. The embedded scene processing information can be extracted from the multimedia source to assist in generating playback of the multimedia source as well as generating a summarized playback of the multimedia source.

Abstract: An apparatus and method for generating a stereo sound has a direct sound positioner, a reverberation positioner, multiple sound integrators, a left reverberation generator and a right reverberation generator. It uses the direct sound positioner and reverberation positioner to produce the directional effect of sounds and uses the left and right reverberation generators produce the spatial effect of the sounds. Further, it adjusts the ratio of the directional sounds and the reverberation via the integrators to achieve the required sound effects.

Abstract: A multi-channel surround sound expansion method is proposed. First, a two-channel stereo sound is read and then expanded into a Front L channel, a Front R channel, a Front M channel, a Rear L channel and a Rear R channel sound signals by means of the Hafler technique. Next, the sound reverberation technique is used to let the Rear L channel and Rear R channel sound signals generate sound with echo/reverberation. Finally, the Rear L channel and Rear R channel sound signals are delayed by a first time value, and the Front M channel sound signal is advanced by a second time value to emphasize the front sound field and the human voices, thereby producing a 3D sound field surrounding a listener.
