摘要： The present invention provides a method and a system for device discovery in wireless communication. One implementation involves scanning one or more wireless channels to discover a partner wireless station for a new transmission, by detecting peak energy and beacons on each scanned channel. If a beacon is not detected, then selecting the clearest channel among the scanned channels, and transmitting beacons on the clearest channel. Upon detecting a beacon from a partner station, establishing association with the partner station and selecting a wireless data channel for communication with the partner station. Another implementation involves discovering a partner wireless station to establish a data channel for communication with a discovering station that is associated with a coordinator station, and transmitting a bandwidth reservation request to the coordinator to reserve channel time for control message exchange between the discovering station and the partner station.

摘要： A system and method for wireless communication of uncompressed video data includes concealing corrupted portions of video data. Video packets received are transmitted over a wireless channel. Each of the video packets includes data blocks forming video data representing at least part of a video frame. Each of the data blocks is encoded with an error correction code. A data block determined to be corrupted is replaced with an uncorrupted data block selected from the data blocks in the video packets. The corrupted data block includes a first displayable element on the video frame and the uncorrupted data block includes a second displayable element on the video frame. The uncorrupted data block is selected at least partially based on proximity between the first and second displayable elements on the video frame.

摘要： A method and system for transmitting video information from a sender to a receiver over wireless channels, by inputting a frame of video information at the sender, packetizing the video information and transmitting the video packet from the sender to the receiver over a wireless channel. Packetizing the video information is performed by segmenting the frame into one or more segments of video information, constructing a data payload from one of the segments, constructing a video header including information describing said one segment, forming a video packet from the video header and the data payload. The video header in each video packet uniquely defines the video information in the data payload of the video packet for the receiver to reconstruct the video frame for proper display of the data payload in a video stream.
