发明名称 SIGNAL PROCESSING APPARATUS, SIGNAL PROCESSING METHOD, REPRODUCING APPARATUS, AND RECORDING APPARATUS
摘要 <P>PROBLEM TO BE SOLVED: To provide a technology of editing contents including video and audio at less expense in time and labor in the case that, e.g. the resonance in response to a position of a sound source in a video image and video contents is coincident with the resonance by a localized position of the sound source so as to reproduce a video/sound field space with much more presence. <P>SOLUTION: A signal processing apparatus disclosed herein acquires audio attribute information associated with an acoustic attribute of an audio signal in response to video contents of a video signal on the basis of an audio synchronization information signal including at least the video signal as an information signal synchronously with the audio signal and applies prescribed audio signal processing to the audio signal on the basis of the audio attribute information. Since the signal processing apparatus can automatically acquire the audio attribute information such as resonance information in response to the position of the sound source in the video and the video contents on the basis of the audio synchronization information signal, it is not required to sequentially manually instruct information of resonance in response to the position of the sound source and the video contents along a time base unlike prior arts. <P>COPYRIGHT: (C)2007,JPO&INPIT
