Patent ID: 8432846

Claim:
A point-to-multipoint wireless display method, comprising steps of a) establishing connection between a data processing device and multiple display devices, b) acquiring pixel data, packetizing the pixel data into pixel data packets in accordance with a predetermined application layer protocol to generate pixel data packets, transferring the pixel data packets to a combined transport and network layer, transmitting the pixel data packets to an Ultra Wide Band (UWB) link layer and then transmitting the pixel data packets via a physical layer over the air at the data processing device side, c) receiving multicast data packets over the air, delivering the multicast data packets to the combined transport and network layer after unpacketizion at the physical layer and the UWB link layer, and unpacketizing the multicast data packets and restoring the pixel data in accordance with the application layer protocol at the combined transport and network layer at the display device side, and d) performing display output according to the pixel data, wherein the combined transport and network layer is a combination of a transport layer and a network layer that use one multicast protocol as a combined protocol, each packet of the multicast protocol contains a multicast address flag, a transmitting side flag, a data type flag, an image data body and a check bit.
