摘要： Method and system for transmission of uncompressed video information from a sender to a receiver over wireless channels are disclosed. For example, according to one embodiment, when channel conditions (e.g., noise or interference) worsens, one or more least significant bits (LSB) of pixel data are not transmitted to save bandwidth for more efficient transmission. Furthermore, the remaining one or more of the most significant bits (MSB) of the pixel data are transmitted with coding and/or modulation schemes that provides extra error protection, relative to what is needed in regular channel conditions.

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 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.
