摘要： A retransmission method and system for time-constrained video packet transmission between a sender and a receiver, wherein the retransmission deadline of each packet is individually adjusted based on the actual decoding time deadline at the receiver decoder. Accordingly, variable retransmission deadlines are set corresponding to the decoding and playback time for each data packet which carries compressed video information. As such, both network efficiency and video transmission quality are improved compared to the conventional retransmission approaches.

摘要： Uncompressed video information is transmitted over a wireless communication medium from a wireless sender device to a wireless receiver device. Progressive transmission data rate adaptation is performed on original uncompressed video pixel information. The progressive transmission data rate adaptation is performed on selected pixel information to obtain a rate-reduced pixel information. The rate-reduced pixel information requires a lower transmission data rate than the original frame. The rate-reduced pixel information is transmitted over the wireless communication medium to the wireless receiver device. At the receiver, a reverse operation is performed to recover the original uncompressed video pixel information.

摘要： A power saving process for wireless communications is provided, wherein a receiving station examines the header of each incoming frame and stops decoding data symbols of the frame, upon determining that the incoming frame is not intended for that receiving station. In one implementation, the receiving station stops receiving and decoding data symbols of the frame by entering a power saving mode. This conserves power at the receiving station.

摘要： A method and system for wireless communication in a wireless network is provided. One implementation involves a requesting wireless station directionally transmitting a request to a coordinator for access to a communication channel; the request packet includes a field indicating the length of the desired reservation period; and upon successfully receiving the request from the wireless station, the coordinator reserving a channel time period for data transmission by the requesting wireless station, and at least pseudo-omni-directionally broadcasting a packet to all wireless stations in the network indicating the reservation. All other stations refrain from contending the channel during the reserved channel time period.

摘要： A system and method for performing medium access control in a system for wireless communication of uncompressed video is disclosed. In one aspect, the system includes one or more high rate channels overlapping with a primary low rate channel and one or more secondary low rate channels. In another aspect, the system includes a communication device configured to communicate a bandwidth request message identifying bandwidth required for communication with another communication device. The bandwidth request message contains information allowing a device coordinator to determine a reserved time slot for communication on a secondary low rate channel when communication is determined not to be possible on a high rate channel. Transmission on the secondary low rate channel is time division duplexed with a high rate channel, where transmission at any one time can take place on either the high rate or the secondary low rate channel.
