Provided are a network node and a method of performing discovery, which may stably perform discovery without delay or crash of a network at the time of initial discovery in a large-scale network. The network node operated in a distributed network includes a discovery performing unit that determines a discovery back-off time that is a transmission wait time of a discovery message based on levels of priority of the network node, and a communication unit that transmits the discovery message using the discovery back-off time.

Apparatus and method of performing discovery based on priority level in distributed network, and method of determining discovery back-off time

A display apparatus having an object-oriented 3D sound coordinate indication is disclosed, in which sounds are outputted from a speaker positioned matching with a coordinate of an object in a matrix speaker apparatus formed of a plurality of small size speakers disposed behind a display apparatus in cooperation with an object content displayed on a display apparatus screen. The display apparatus having an object-oriented 3D sound coordinate indication comprises a center channel decoder which receives an audio signal corresponding to a center channel speaker among the audio signals outputted from a decoder of the surround speaker system and separates into sound sources based on an object; a center channel matrix for setting the coordinates of sound sources based on the objects separated by the center channel decoder; a matrix amplifier for amplifying an output sound of a speaker matching with each coordinate value of the sound sources based on the object; and a plurality of speakers which are arranged in a matrix shape behind the display monitor, whereby sounds are outputted through the speakers corresponding to the coordinates of the objects displayed on the display monitor.

Display apparatus having object-oriented 3D sound coordinate indication

A control method and apparatus for displaying moving pictures are disclosed, which make it possible to significantly reduce a side effect occurring when watching a 3D moving picture, in particular, a side effect such headache, nausea or dizziness generally occurring when a watcher watches a 3D moving picture while a watcher watches an excellent 3D moving picture. The method for displaying moving pictures comprises a step for receiving a data source containing a moving picture, a variable filtering information of the moving picture which is in time-sync with the moving picture and controls the fatigue that a user feels in the course of watching moving pictures, and a filter mask image code; a step for filtering the moving pictures with respect to the section in which the filtering is set depending on the variable filtering information and the filter mask image; and a step for outputting the filtered moving pictures.

The present invention provides a lightweight multicast method and apparatus for a data distribution service. The lightweight multicast apparatus includes a network congestion detection unit for multicasting packets to a plurality of subscriber node terminals, and detecting a cause of network congestion using a negative response message transferred from a relevant subscriber node terminal that could not receive the packets among the plurality of subscriber node terminals. A network recovery control unit determines a recovery control policy depending on the cause of the congestion detected by the network congestion detection unit, and solves the cause of the congestion.

Lightweight multicast method and apparatus for data distribution service

The present invention relates to an apparatus for controlling the movement of a cone paper used for outputting sound, and a flexible OLED covered on the cone paper in order to enhance the sound quality of a visual speaker. In a visual speaker which includes a voice coil, a magnet, an edge, a unit enclosure, a flexible OLED for displaying video images, and a speaker cone paper, a visual speaker is characterized in that a speaker cone paper configured to output sound, a flexible OLED covered on the speaker cone paper, an edge, and a unit enclosure are formed in an integral airtight structure filled with a compressed gas, and a compression piston and a compressed gas adjusting device are further disposed for adjusting the pressure of the inner compressed gas, so that it is possible to control the movements of the flexible OLED and the speaker cone paper.
