Abstract: Provided are a method and an apparatus for increasing call quality while reducing consumption of bit rates in immersive multimedia communication. A method of transmitting, by a terminal device, an audio signal to a counterpart terminal device, includes: extracting head tracking information of a user of the counterpart terminal device from a packet received from the counterpart terminal device; predicting a head direction of the user of the counterpart terminal device after a predetermined time period, based on the extracted head tracking information; generating audio output signals by combining audio input signals received via a plurality of microphones, based on the predicted head direction; and transmitting information about the predicted head direction and a sound frame in which the audio output signals are compressed, to the counterpart terminal device.

Abstract: A frame error concealment (FEC) method is provided. The method includes: selecting an FEC mode based on states of a current frame and a previous frame of the current frame in a time domain signal generated after time-frequency inverse transform processing; and performing corresponding time domain error concealment processing on the current frame based on the selected FEC mode, wherein the current frame is an error frame or the current frame is a normal frame when the previous frame is an error frame.

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.
