摘要： A method and system for transmitting video information from a sender to a receiver over a wireless channel, is provided. Video information bits are placed into multiple data packets, and transmitted in a burst sequence from a sender to a receiver over a wireless channel in a first time frame. Transmission of each data packet is separated from transmission of the next data packet by an inter-frame time period which is shortened by a channel switching duration. Then, selected video information bits are retransmitted to from the sender to the receiver in a second time 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.

摘要： A method and system for device discovery in a wireless network is provided. The device discovery involves directionally transmitting a data unit from a transmitting station over a channel in different directions to emulate omni-directional transmission, receiving the data unit transmissions from different directions at a receiving station, determining the quality of the transmissions received from the different directions, and detecting location information for the transmitting station relative to the receiving station based on the highest quality transmission among the transmissions received from the different directions. Further, if a channel has sufficient bandwidth to satisfy direct link communication between two stations, then during a direct link set-up stage, the two stations conduct a probing message exchange using omni-direction transmission, and upon successful probing, obtain communication link status information and set proper communication configurations for the two stations based on the communication link status information.

摘要： A method and system for transmitting video information from a sender to a receiver over a wireless channel is provided. Video information bits are placed into one or more data packets at the sender, and each data packet is transmitted from the sender to the receiver over a wireless channel during a current time frame. For each transmitted data packet, the sender receives a corresponding acknowledgment packet from the receiver. The sender then performs burst retransmission of the negatively acknowledged packets during a next time frame comprising a BeamTrack Group for transmission of further data packets from the sender to the receiver over a wireless channel. The receiver utilizes each retransmitted data packet to recover a lost or erroneously received data packet.

摘要： A method and system for communication of uncompressed video information over a wireless channel, involving partitioning neighboring pixels in a video frame into different packets and transmitting the packets separately over a wireless channel. Redundancy information is generated for pixels in one or more packets and transmitted over the wireless channel. In case of packet loss or damage, the redundancy information can be used to recover the pixels in the lost or erroneous packet. The redundancy information can be transmitted to a receiver on a different channel than said packets. The redundancy information can be transmitted in one or more packets among the original pixel data packets.

摘要： A method and a system for bit reorganization and packetization of uncompressed video for transmission over wireless communication channels. The bit stream of the uncompressed video is reorganized according to importance levels of video bits. Then, various unequal protection methods such as encoding are applied to bits at different video importance levels. The reorganized and encoded information is then transmitted from a transmitter to a receiver over a wireless channel. The receiver performs the reverse steps of the transmitter, along with error detection/correction as needed, to recover the uncompressed video information.
