Abstract: There is provided an object attribute-based watermarking method for preventing leakage of a digital content. A video watermarking method according to an embodiment may acquire a requested video and watermarking information upon receiving a request for video streaming from a user, may determine some of objects appearing in the video according to the watermarking information, may transform attributes of the determined objects, and may stream the transformed video. Accordingly, by watermarking an attribute of an object appearing in a video differently according to a user and providing the video, a watermark may be difficult to perceive, robustness against various attacks may be guaranteed, and a leakage path of a content may be checked.

Abstract: Disclosed herein is a power line channel-adaptive communications system and method. The power line channel-adaptive communications system includes a transmitting end, a channel-adaptive controller, and a receiving end. The transmitting end generates an adaptive chirp symbol signal of a preset type for transmission data according to a channel state of the power line, modulates the generated adaptive chirp symbol signal in any one of first and second transmission modes, and transmits the modulated adaptive chirp symbol signal via the power line channel. The channel-adaptive controller controls the type and transmission mode of the adaptive chirp symbol signal. The receiving end restores the transmission data by demodulating the adaptive chirp symbol signal, received via the power line channel, in any one of the first and second transmission modes according to the channel state of the power line.

Abstract: Method and system for virtual multicast networking, which can provide multicasting application service on non-multicast network that does not support multicast, are provided.

Abstract: The invention relates to a multicasting relay method to secure a significantly increased number of simultaneous multicasting connectors under an identical network environment (B-RAS, NAS or the like) with no addition of service device under a modem environment utilizing xDSL and PSTN and a recording medium readably by a computer recorded with programs, the method comprising the steps of: prompting a contents providing server to induce the first xDSL connector terminal to an xDSL server (B-RAS) (step 1); broadcasting a multicasting broadcasting data to the xDSL connector server in real time (step 2); discriminating whether a relevant xDSL ser§ice device supports the multicasting (step 3); broadcasting the multicasting broadcasting data to the first xDSL connector terminal in real time and prompting the xDSL service device to receive the broadcasting data at a multicasting address (step 4); and relaying multicasting data to the second xDSL connector terminal from the xDSL service device of the relevant xDSL ser

Abstract: The present invention relates generally to multicasting technology in an Internet broadcasting system and, more particularly, to a method and system for voting an optimal route in multicasting, which, when an abnormality, such as the delay or disconnection of a video stream, occurs during the reception of a predetermined or larger amount multimedia data which is multicasted by a main server, in stream form, set the specific one of a plurality of audio transmission routes, that has the highest transmission speed, as a video transmission route, and set the transmission route through a level-down, level-up, or level-shift operation depending on the latency values or threshold values of respective transmission routes, thus allowing a large size multimedia stream to be seamlessly and rapidly transmitted. In accordance with the present invention, it is possible to always prepare an optimal transmission route and stably and rapidly transmit a multimedia stream.

Abstract: The present invention relates to a system and method for controlling the transmission of moving image data through a network. The system for controlling the transmission of moving image data through a network of the present invention includes a server and a client. The server transmits key frames and delta frames of a compressed moving image stream in a form of packets through a multimedia communication network, and controls interruption of transmission of subsequent delta frames and continuation of transmission only from a subsequent key frame, depending on whether a specific delta frame is lost, based on a response signal indicating reception of each packet. The client receives packets corresponding to the key frames and the delta frames, obtained from the compressed moving image stream, from the server, and transmits the response signal indicating reception of each packet to the server.
