Abstract: The present invention relates to an apparatus and method for transmitting/receiving streaming data using multiple paths, in which the streaming data is smoothly reproduced without being interrupted, and more particularly, to an apparatus and method for transmitting/receiving streaming data using multiple paths, in which exchange of the streaming data is performed in real-time using the multiple paths regardless of obstacles. The method for transmitting streaming data using multiple paths includes managing and maintaining a path list including sequence information about a transmission path capable of transmitting data, framing the streaming data, and transmitting the framed streaming data via the transmission path according to the sequence information.

Abstract: Methods for transmitting and receiving data of a station includes setting a direct route to a corresponding station and a relay route to a relay device, selecting one route as between the direct route and relay route, and transmitting and receiving data through the selected route. A non-transitory computer-readable storage medium may store a program including instructions to cause a computer to perform the method. The setting may be performed by a processor and the transmitting and receiving may be performed respectively by a transmitter and a receiver.

Abstract: Provided is a method and apparatus for setting a detour path in a wideband high frequency wireless system using a centralized Media Access Control (MAC) protocol. Here, in a wireless system using the centralized MAC protocol where a time synchronization and a band allocation may be performed by a single central control unit, when a signal blockage occurs while a data communication is being performed via a direct path between a source device and a destination device, the detour path may be quickly provided.

Abstract: Disclosed are an Unequal Error Protection (UEP) apparatus and method thereof for transmitting various types of uncompressed video signals in a broadband high frequency wireless system. The UEP apparatus may include a UEP transmission controller to verify a bit separation point of separating a color depth and priority for each pixel element being composed of a video data pixel when video data is inputted, and to control an error correction coding of correcting relatively many errors to be used in information with a high priority for each pixel element, a bit separator to separate the video data pixel through a control of the UEP transmission controller based on the priority for each pixel element, and a channel coding unit to use a corresponding error correction coding through the control of the UEP transmission controller based on the priority for each pixel element.
