WIRELESS HD

WirelessHD is an effort of the consortium led mainly by LG , Matsushita, NEC, Samsung, SiBEAM, Sony and Toshiba to define a standard for the next generation wireless digital network interface specification for wireless high-definition signal transmission for consumer electronics products and they intend to finalize on one standard by spring 2007. The WirelessHD (WiHD) is designed and optimized for wireless display connectivity thereby achieving high-speed rates from 2 Gbit/s to 5 Gbit/s for the CE, PC, and portable device segments in its first generation implementation. This standard aids in uncompressed, digital transmission of HD video and audio signals, making it like wireless HDMI, in theory. data rates as high as 20 Gbit/s (compared to 10.2-Gbit/s for HDMI 1.3)are possible with its core technology, permitting it to scale to higher resolutions, color depth, and range.
The signal will operate on the 60 GHz frequency band which currently requires line of sight between transmitter and receiver and apparently will sport the bandwidth required to support both current and future HD signals. This is far from the real aim of the WiHD, which would be maintain the elegance of the hang-on-the-wall plasmas and LCDs by tucking away the components and wires in a cabinet. The goal for the first line of products will be in-room, point-to-point , non line-of-sight (NLOS) at up to 10 meters. There much work to be done to improve interoperability among devices, and also to expand the capabilities of personal video players, PDAs, and other handheld devices.
