摘要： There was no method of positioning virtual sound sources of object signals obtained from received coded object information, in a listening space on a receiving site side. Provided are an object decoding unit (806) that receives a plurality of pieces of coded acoustic information coded on an object basis and decodes the received coded acoustic information on an object basis to generate object signals, and an a rendering unit (807) that positions, for each acoustic signal resulting from synthesizing the object signals, a virtual sound source of each of the object signals resulting from the object-based decoding, in a listening space, and priority information indicating a priority of the acoustic signal is multiplexed with the coded acoustic information, and the rendering unit (807) determines, with reference to the priority indicated in the priority information or the number of object signals included in the acoustic signal, a size of an area of the listening space which is allocated to the acoustic signal, and positions, within the area, the virtual sound source of each of the object signals included in the acoustic signal.

摘要： An object decoding unit receives a plurality of pieces of coded acoustic information coded on an object basis and decodes the received coded acoustic information on an object basis to generate object signals. A rendering unit positions, for each acoustic signal resulting from synthesizing the object signals, a virtual sound source of each of the object signals resulting from the object-based decoding, in a listening space, and priority information indicating a priority of the acoustic signal is multiplexed with the coded acoustic information. The rendering unit determines, with reference to the priority indicated in the priority information or the number of object signals included in the acoustic signal, a size of an area of the listening space which is allocated to the acoustic signal, and positions, within the area, the virtual sound source of each of the object signals included in the acoustic signal.
