Disclosed are an acoustic echo cancelling apparatus and an acoustic echo cancelling method. The acoustic echo cancelling apparatus comprises a first capturer configured to capture a remote audio signal received from a remote machine; a second capturer configured to capture a local audio signal that is input to a local microphone; an acoustic echo canceller (AEC) configured to cancel an acoustic echo of the local audio signal using the remote audio signal and output a local audio signal from which the acoustic echo is cancelled; and a transmitter configured to transmit an output signal of the AEC to the remote machine.

Acoustic echo cancelling apparatus and method

Provided are a conference system and a method for controlling bandwidth thereof. According to embodiments of the present disclosure, the conference system enables a bandwidth pattern obtained from one terminal to be shared with other terminals connected to the conference in the same area as the terminal, such that a process of identifying bandwidths of users connected to the conference in the area may be omitted, thereby reducing a time required for stabilizing a service quality.

Conference system and method for controlling bandwidth thereof

A conference system and a method of switching a connection terminal in the conference system are provided. The conference system according to one embodiment of the present disclosure includes a web conference server configured to receive a request for switching a connection terminal from a first terminal and acquire identification information of a second terminal included in the request for switching a connection terminal; and an audio conference server configured to process a connection of the second terminal to an audio conference and transmit identification information of the second terminal to the web conference server, wherein the web conference server compares the identification information of the second terminal acquired from the first terminal with the identification information of the second terminal received from the audio conference server and updates participant information of the audio conference, which is mapped with participant information of the web conference.

Conference system and method for switching connection terminal thereof

A conference system and a method for handling a conference connection in the conference system are provided. The method for handling a conference connection according to one embodiment of the present disclosure includes: providing, at a web conference server, a terminal with an access link to a web conference; acquiring, at the web conference server, identification information of the terminal from the terminal connected to the web conference through the access link; processing, at an audio conference server, a connection of the terminal to an audio conference; receiving, at the web conference server, identification information of the terminal connected to the audio conference from the audio conference server; and mapping, at the web conference server, participant information of the web conference and participant information of the audio conference by comparing the identification information received from the terminal with the identification information received from the audio conference server.

Conference system and method for handling conference connection thereof

A conferencing apparatus and a method for switching an access terminal therein are provided. The conferencing apparatus according to one embodiment of the present disclosure includes: a conference information management module configured to generate mapping information for terminal identification information of a first terminal and access information of a conference participant who is accessing a conference through the first terminal; and an access switch module configured to provide a token corresponding to the mapping information to the first terminal according to an access terminal switch request from the first terminal and, when the token is received from a second terminal, switch a terminal of the conference participant from the first terminal to the second terminal according to validity of the received token.

Conferencing apparatus and method for switching access terminal thereof

A conference system and a method for interworking between an audio conference and a web conference in the system are provided. The method for interworking between an audio conference and a web conference according to one embodiment of the present disclosure includes recognizing, at an audio conference server, an access of a host terminal to an audio conference and activating the audio conference, transmitting, at the audio conference server, a notification of activation of the audio conference to a web conference server, and activating, at the web conference server, a web conference corresponding to the audio conference according to the notification of activation of the audio conference.

Conference system and method for interworking between audio conference and web conference

Provided are a conference access method and a terminal for performing the same. A terminal according to an embodiment of the present disclosure includes: an interface configured to receive a plurality of different access addresses for access to a conference from a conference server; an access attempter configured to attempt to simultaneously access the conference via each of the plurality of access addresses; and a priority allocator configured to collect an access result for each of the plurality of access addresses, and to allocate an access priority to each of the plurality of access addresses based on the access result, wherein the access attempter attempts to access the conference via an access address having a highest access priority among the plurality of access addresses.

Conference access method and terminal for performing the same

A terminal for connecting to a conference via a network according to an embodiment of the present invention includes an image acquisition unit configured to acquire each participant image received from a plurality of other terminals connected to the conference, a network monitoring unit configured to monitor performance of the network, an image analyzer configured to analyze the each participant image to acquire one or more of image information, speech information, and quality information of the each participant image when the performance of the network changes, and a quality controller configured to change the quality of at least some of the participant images according to the analysis result of the each participant image.

Method for adjusting image quality and terminal and relay server for performing same

An apparatus for providing multi-party conference and a method for assigning an encoder in the apparatus are provided. The apparatus for providing multi-party conference according to one embodiment of the present disclosure includes: an image quality determination module configured to determine an image providing quality for a terminal connected to a multi-party conference created in the apparatus; and an encoder assignment module configured to assign an encoder to the terminal based on the image providing quality, wherein when an assignable encoder does not exist at the time of assigning the encoder, the encoder assignment module retrieves one encoder among previously assigned encoders and assigns the retrieved encoder to the terminal.

Apparatus for providing multi-party conference and method for assigning encoder thereof

Disclosed are a sound sharing apparatus and a sound sharing method. The sound sharing apparatus according to one embodiment of the present disclosure includes at least one processor configured to implement: a modifier configured to change a default audio render driver of a local machine from a first audio render driver to a second audio render driver; a capturer configured to capture audio data transmitted to the second audio render driver; and a mixer configured to mix the captured audio data: i) with first voice data to output first mixed data, wherein the first voice data is received from a remote machine connected to the local machine through a network, or ii) with second voice data to output second mixed data, wherein the second voice data is received input through a microphone of the local machine.
