    摘要： A method and system for transmission of video information is provided. A transmitting wireless station performs chroma partitioning of pixels in a video frame into different partitions. The chroma partitioning includes separating luminance (Y) information from chrominance information (CB and CR) of each pixel in a set of spatially correlated pixels. The luminance (Y) information are placed into different partitions. The different partitions into different packets and transmitted over a wireless communication medium to a receiving wireless station. The video information is selectively adapted to a lower data transmission rate with reduced quality degradation by dropping less important partitions.

    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： Communication of stereoscopic three dimensional (3D) video information. One embodiment comprises wireless communication of stereoscopic 3D video information including an uncompressed first eye view video frame and a corresponding stereoscopic uncompressed second eye view video frame, from a transmitting wireless station to a receiving wireless station. In one embodiment, a set of pixels in an uncompressed first eye view video frame is transmitted over a wireless communication medium. Pixel information in a set of pixels in an uncompressed second eye view video frame corresponding to the first eye view set of pixels is reduced to generate a reduced set of pixels. The reduced set of pixels is transmitted over the wireless communication medium. At the receiving wireless station, an uncompressed second eye view video set of pixels is reconstructed based on said first eye view set of pixels and said reduced set of pixels.
