Claim One:
1. A method of generating multi-channel control signals, the method comprising: by a hardware-based processor: representing locations of a plurality of speakers as a mesh structure including a plurality of polygons whose vertices are corresponding to the locations of the plurality of speakers; acquiring a location of an object in a current video frame; calculating a plurality of distances between the plurality of polygons included in the mesh structure, and the acquired location of the object, respectively; selecting a polygon among the plurality of polygons included in the mesh structure based on the plurality of distances; generating the multi-channel control signals corresponding to a plurality of speakers located in the selected polygon; and transmitting the multi-channel control signals to the plurality of speakers located in the selected polygon, to reproduce a sound corresponding to the object via the plurality of speakers located in the selected polygon, and wherein the selected polygon corresponds to a shortest distance among the plurality of distances.
