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

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

A non-volatile memory device includes a plurality of memory blocks. Each of memory blocks includes a main area including a plurality of first memory cells having a phase-change material and a spare area including at least one second memory cell for storing initial information about the plurality of first memory cells. In the non-volatile memory device, a circuit of the at least one second memory cell is cut off according to the initial information, and the initial information is defective block information that is information about a defect of the plurality of memory blocks.
