Method and apparatus for operating multiple speakers using position information

摘要

A method for detecting a plurality of available sound output devices when audio data is played back, and for detecting user position information and user direction information is provided. The method includes generating a plurality of pieces of sound information from the audio data, based on at least one of the detected user position information and the user direction information, and distributing each of the plurality of pieces of sound information to a corresponding sound output device from among the plurality of sound output devices.

1. A method of operating multiple speakers, the method comprising:
detecting a plurality of available sound output devices when audio data is played back; detecting user position information and user direction information of a user; generating a plurality of pieces of sound information from the audio data, based on at least one of the detected user position information and the user direction information; and distributing each of the plurality of pieces of sound information to a corresponding sound output device from among the plurality of available sound output devices; recognizing a change in at least one of a position and a direction of the user; when a change in at least one of the position and the direction of the user is recognized, re-detecting at least one of the user position information and the user direction information; and regenerating a plurality of pieces of sound information from the audio data, based on the at least one of re-detected user position information and the user direction information, wherein the regenerating of the plurality of pieces of sound information comprises converting a number of sound output channels from m to n (m>0, n>0, m≠n).
