A non-transitory computer-readable recording medium may storing instructions that, when executed by a processor, cause the processor to set a communication session for a conference in which a plurality of users participates through a server, transmit, to the server, an identifier of an avatar to be represented on a virtual space for the conference and coordinate information of the avatar in the virtual space, receive, from the server, resources of neighboring avatars selected based on the coordinate information, transmit, to the server, motion data of the avatar through the communication session, receive, from the server, motion data of the neighboring avatars through the communication session, and represent the neighboring avatars on the virtual space based on the resources of the neighboring avatars and the motion data of the neighboring avatars.

Method and system for processing conference using avatar

Disclosed are methods and systems for controlling audio using an asymmetric channel of an audio conference. An audio control method may include establishing, by a processor included in a computer apparatus, a bi-directional media session having an asymmetric channel structure between a first participant among a plurality of participants participating in an audio conference and a mixer, receiving, by the processor, first audio data from the first participant through a media session of a first channel structure in the bi-directional media session, mixing, by the processor, second audio data of at least two participants excluding the first participant from among the plurality of participants, using a multichannel, and transferring, by the processor, the mixed audio data of the at least two participants mixed using the multichannel to the first participant through a media session of a second channel structure in the bi-directional media session.

Method and apparatus for controlling audio using asymmetric channel of audio conference

A method and a system for performing a group call using unicast and multicast are provided. A group call method performed by a first client device, may include: establishing a media session with a server providing a group call service based on a group call request from the first client device; transmitting, to the server through the media session, at least one first packet including a first source identifier of the first client device; providing a user interface at the first client device, that enables selecting at least one second client device from a plurality of second client devices that participate in a group call initiated by the first client device; and transmitting, from the first client device to the server, at least one second packet including a second source identifier of the selected at least one second client device as a destination of data included in the at least one second packet.

Method and system for group call using unicast and multicast

Disclosed is a terminal connection method for multimedia communication. The terminal connection method may reduce or minimize the use of an access network by bridging a connection between access networks of two terminals through an internal application server (iAS).
