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 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 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.
