Abstract: Disclosed are a user terminal device and a control method therefor. The control method for a user terminal device according to the present invention comprises the steps of: determining state information of a satellite device connected with a user terminal device when a call request message is received from another terminal device; determining communication configuration information with the another terminal device on the basis of the state information of the satellite device, and transmitting a call response message including the communication configuration information to the another terminal device; and receiving audio data from the another terminal device according to a communication scheme corresponding to the communication configuration information. Therefore, in comparison with the prior art, the present invention can reduce a call negotiation time between user terminal devices, and thus reduce a call cost.

Abstract: A method of encoding a multi-channel 3-dimensional (3D) audio signal mixed with a multi-channel 3D object signal is provided. The method includes: obtaining a location parameter indicating a virtual location of the multi-channel 3D object signal on a multi-channel speaker layout based on a gain value of the multi-channel 3D object signal for each channel; and encoding the multi-channel 3D audio signal and the location parameter.
