    • PURPOSE: A method and a system for selecting a transponder-recognition station are provided to select a wireless relay station from candidate wireless relay stations based on an evaluation result for a driving parameter of the candidate wireless relay stations. CONSTITUTION: A source station transmits a wireless relay selection request frame to a destination station(203). The source station executes a required beam-forming training process or a channel estimation process with each wireless relay station(205). The destination station executes the required beam-forming training process or a channel estimation process with each wireless relay station(206). The destination station transmits a plurality of relay channel measurement report to the source station(207). The source station selects the suitable relay station from the candidate relay stations(209).

    • PURPOSE: A method for data streaming multiplexing in an AV(Audio/Video) network and a system thereof are provided to supply multiplexing of asynchronism and synchronism data for supporting asynchronism data without a dedicated communication channel through wireless communication links. CONSTITUTION: A corresponding AV device receives a request control message, which includes a channel setting request for setting an AV stream, from an upstream AV device(71). The corresponding AV device determines usable resources for satisfying a requested stream bandwidth(72). When enough resources are usable, the corresponding AV device assigns the resources(74). When a receiving side of the request control message is not a destination AV device, the request control message is forwarded to a downstream AV device by using data/control forwarding sub-table information(75,76). [Reference numerals] (71) Receive channel setup request messages; (72) Resource available?; (73) Generate error messages; (74) Allocate stream with a port, lane(s), and a time unit per bandwidth request; (75) Sink device?; (76) Forward forwarding information request messages; (AA) Start; (BB,DD) No; (CC,EE) Yes; (FF) End
    • 目的:提供一种用于AV(音频/视频)网络及其系统中的数据流多路复用的方法,用于通过无线通信链路提供用于支持异步数据的异步和同步数据的复用,而不需要专用通信信道。 构成:相应的AV设备从上游AV设备(71)接收包括用于设置AV流的信道设置请求的请求控制消息。 相应的AV设备确定用于满足所请求流带宽的可用资源(72)。 当足够的资源可用时,对应的AV设备分配资源(74)。 当请求控制消息的接收侧不是目的地AV设备时,通过使用数据/控制转发子表信息将请求控制消息转发到下游AV设备(75,76)。 (附图标记)(71)接收信道建立请求消息; (72)可用资源?
