摘要： A method and system for communication between audio/video (AV) devices. In one embodiment communication between AV devices includes establishing an AV path stream for AV data streaming between a source AV device and a destination AV device, wherein each AV device includes one or more I/O ports for connecting the AV device to another AV device via a communication link including multiple communication lanes. Asynchronous and isochronous AV data is multiplexed for transmission via one or more fixed length data cells, each data cell capable of carrying one or more of: an asynchronous data symbol and an isochronous data symbol. Multiplexing includes selectively mapping asynchronous data onto isochronous symbols for transmission during a video blanking period. One or more data cells are transmitted from a physical layer of the source AV device to the destination AV device, via one or more communication lanes.

One implementation comprises establishing isochronous connection between a source AV device and a destination AV device. Each AV device includes multiple I/O ports for connecting the AV device to another AV device via a communication link comprising multiple communication lanes. The isochronous connection is established by determining end-to-end temporal and spatial lane availability between the source AV device and the destination AV device to support a target date rate. Communication resources are allocated on the available lanes based on the target date rate for isochronous communication between the source AV device and the destination AV device.

摘要： A method and system for data communication in a wireless network is provided. A wireless transmitter transmits a locality check message from a wireless transmitter to a wireless receiver over a wireless communication medium. Upon receiving a locality check response message from the wireless receiver, the wireless transmitter marks the locality check response message as valid even if it arrives after an original locality check time period since transmission of the locality check message, but before the end of an adjusted locality check time period. The adjusted locality check time period comprises said original locality check time period adjusted by delays in processing layers at the transmitter and wireless communication medium access delays in data communication between the wireless transmitter and the wireless receiver.

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.
