Abstract:
PURPOSE: A network-adaptive variable stream layered method and apparatus for video streaming are provided to convert a frame of video data transmitted to a reception terminal having a reduced available bandwidth among reception terminals receiving video data in an IP-based wired/wireless network environment in order to provide a continuous streaming service. CONSTITUTION: A network-adaptive variable stream layered apparatus(400) comprises: a stream analysis unit(440) which outputs NAL information of a video stream by analyzing a video stream compressed H.264/AVC; a map table generation unit which arranges a frame included in the video stream based on the outputted NAL information; and a rate control unit(430) which selectively removes or selects the arranged frame in consideration of the NAL information and the packet loss rate of the available bandwidth of each reception terminal.

PURPOSE: A user equipment and advertisement service server for providing a bi-directional personalized advertisement is provided to solve the dependency on a certain media service by selecting personalized advertisement contents based on advertisement meta information and user setup information. CONSTITUTION: A communication unit(110) receives user setup information and advertisement meta information from an advertisement service server. A storage unit(120) stores the user setup information and the advertisement meta information, and a control unit(130) includes an advertisement selection unit(131). When an advertising event happens, the advertisement selection unit selects advertisement contents corresponding to the user set information by searching the advertisement meta information. A display unit(140) displays the selected advertisement contents.

Abstract:
A control device for controlling wireless communications connection between communications devices according to one embodiment of the present invention includes a communications unit which wirelessly communicates with a first communications device and a second communications device, a user interface unit which generates a communications unit activating signal according to the control of a user, and a control unit which activates the communications unit according to the communications unit activating signal. The communications unit receives communications connection information for communications between the first and second communications devices from the first communications device and transmits the communications connection information to the second communications device.
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.
