摘要： A method and system for isochronous data stream management in high speed audio/video networks. One implementation comprises isochronous communication management between audio/video (AV) devices by maintaining forwarding information for forwarding data between AV devices, wherein each AV device includes multiple I/O ports for connecting the AV device to another AV device via a communication link including multiple communication lanes. The forwarding information is utilized to communicate AV path set-up request and response control messages between a source AV device and a destination AV device via said communication link, and allocating isochronous communication resources for AV data streaming, for establishing AV path streams for bi-directional isochronous AV data streaming between the source and destination AV devices.

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.
