Abstract:
PURPOSE: A multicast control apparatus in a multi hop network capable of optimizing a multicast transfer rate is provided to transfer a query message of a group management protocol packet to the entire network. CONSTITUTION: A multicast control apparatus(105) includes a packet determining unit(201), a packet type discriminating unit(203), and a packet transmitting unit(205). The packet determining unit determines a group management query device. The packet type discriminating unit discriminates a packet type in case the packet is a group management protocol packet. The packet transmitting unit transmits the packet to a second port in case the packet is a query message.
Abstract:
An apparatus and a method for servicing an online multi-user golf game are provided to enable another participant and a user to share swing postures of the participant and user, thereby checking the swing postures of themselves. A session obtaining unit(201) transmits an access request message to obtain a communication session with other participants from a game server. A data communication unit(202) receives a swing image photographing a golf swing posture of a user, voice of a user, and sensing data sensed from swing of the user, transmits the received data in real time and receives swing images, voice and sensing data of the other participants in real time. A simulation unit(204) simulates swing result of other participants and the user by using sensing data of other participants and the user. An output unit(205) outputs the swing image, voice and simulated swing result of other participants and the user.
Abstract:
A method and a system for remote control of an IPTV terminal are provided to remotely control the IPTV terminal by using one a control server and mounting a control module of a terminal without changing configuration of hardware and software of the IPTV terminal, thereby facilitating the remote control about a state and a service of the IPTV terminal. A plurality of IPTV(Internet Protocol Television) terminals(400) has a control module processing a remotely transmitted control message. And the IPTV terminals change a state and a service according to the control message through the control module. A control server(300) remotely controls the state and service of the IPTV terminal by generating the control message. A database(200) stores each IPTV terminal information.

Abstract:
PURPOSE: A three dimensional image display device and a display method are provided to reconstruct three-dimensional image by using control information which is obtained from a control information acquiring device. CONSTITUTION: A display method of a three dimensional image display device control information acquiring device comprises the following steps: a control information acquisition unit(17) is input control information; a three-dimensional broadcasting receiving unit(16) uses the control information delivered from the control information acquiring device as a key; the three dimension broadcasting receiving unit controls binocular parallax between the first image and the second image by using the control information; and the three dimension broadcasting receiving unit processes image division, object division, and binocular parallax control.
Abstract:
PURPOSE: An overlay multicast system and method thereof for a group media transmission application service are provided to perform merge, partition, transmission of additional stream and main stream that is inputted from a parent node. CONSTITUTION: A merge unit(110) merges additional stream in multi stream and main stream that is inputted from a parent node. A division unit(120) selectively divides main stream or additional stream from multi stream. A recording unit(130) records stream correlation information. An analysis unit(140) determines the merge of stream in a corresponding node.
Abstract:
PURPOSE: An apparatus for mixing a video stream and a method thereof are provided to guarantee real time characteristic in the mixture of a plurality of video streams by mixing compacted video streams as one of compacted video of the desired screen configuration in the compressed domain. CONSTITUTION: An input buffer unit(10) receives the input of a plurality of compacted video streams. A stream analyzing unit(20) analyzes the bit string of the inputted video stream. A stream mixing unit(30) selectively varies slider header area of a plurality of compacted video stream bit strings according to the screen configuration based on the analyzed result. An output buffer unit(40) outputs the mixed compacted video stream according to the slice header zone change.
