Claim Text:
1. An apparatus for generating a side information bitstream of a multi-object audio signal, comprising: a spatial cue information input unit configured to receive spatial cue information generated in an encoder of the multi-object audio signal; a preset information input unit configured to receive preset information for the multi-object audio signal; and a side information bitstream generator configured to generate the side information bitstream based on the spatial cue information and the preset information, wherein the side information bitstream includes a frame region, wherein the frame region includes the preset information for rendering a multi-object audio signal corresponding to a frame wherein the preset information includes (i) a layout of a playback system for a mono system, a stereo system and multi-channel system, (ii) an audio object ID, (iii) object location, (iv) object level and (v) an azimuth degree and an elevation degree of the object, wherein the preset information is used to define audio scene for rendering a multi-object audio signal.
