摘要： A system and method using a medium access control (MAC) header for a wireless communication system including an application layer, a MAC layer, and a physical (PHY) layer is disclosed. The MAC header accommodates time-delay insensitive data transfer between devices located in the network. The MAC header finds particular benefits in short range networks that transfer high definition (HD) video between components. One embodiment of the invention comprises a method of transferring data in a wireless communication network for uncompressed video including fragmenting the data into a plurality of data packets; appending a PHY header to at least one of the data packets to form a MAC frame; setting a field in the PHY header to indicate that the packets do not contain audio video (A/V) data; and transmitting the MAC frame to another device in the wireless communication network.

In addition, the scheme of common beacons and individual beacons is described. Common beacons are broadcast omni-directional at the beginning of each superframe with low data rate and individual beacons are unicast to individual devices directionally with high data rate. A common beacon contains information intended for all of the devices of the network. An individual beacon contains information intended for one particular device.

摘要： A system and method for wireless communication of uncompressed video data includes concealing corrupted portions of video data. Video packets received are transmitted over a wireless channel. Each of the video packets includes data blocks forming video data representing at least part of a video frame. Each of the data blocks is encoded with an error correction code. A data block determined to be corrupted is replaced with an uncorrupted data block selected from the data blocks in the video packets. The corrupted data block includes a first displayable element on the video frame and the uncorrupted data block includes a second displayable element on the video frame. The uncorrupted data block is selected at least partially based on proximity between the first and second displayable elements on the video frame.

摘要： A system implementing a method for multi-band wireless communication packetizes a block of source video information into a first packet, and packetizes the block of source video information into a second packet corresponding to the first packet, wherein the first packet and the second packet include corresponding video information. The first packet and the second packet are transmitted from a transmitting multi-band wireless station comprising a first radio for communication over a first wireless band, and a second radio for communication over a second wireless band. The first packet is transmitted over the first wireless band and the second packet is transmitted over the second wireless band. The first wireless band operates at a higher transmission rate than the second wireless band. A multi-band receiving wireless station reconstructs the source video based on packets arriving on different bands.

摘要： A high accuracy clock synchronization mechanism between a sender and a receiver in a communication network achieves time synchronization using broadcast beacons, directly at the PHY/MAC layer of the sender and the receiver, to minimize synchronization delay jitter. This provides a more efficient synchronization method than either NTP or SNTP, because multiple handshaking information exchange is avoided. Further, using beacons avoids the overhead of introducing additional synchronization packets in higher layer synchronization.
