WirelessHD is an industry-led effort to define a specification for the next generation wireless digital network interface specification for wireless high-definition signal transmission for consumer electronics products. The consortium behind the standard includes among others LG, Matsushita, Samsung, Sony and Toshiba, and aims to have a finalized specification in spring 2007.

In electronics, a digital network is a coupled network of digital components, such as logic gates, that implement a logic system. ... Look up interface in Wiktionary, the free dictionary. ... Generally, high-definition refers to an increase in resolution or clarity such as in: High-definition television (HDTV), television formats that have a higher resolution than their contemporary counterparts High-definition video, which is used in HDTV broadcasting, as well as digital film and computer HD video file formats HDV... Consumer electronics is electronic equipment intended for use by everyday people. ... LG can refer to a number of things: LG Group, a South Korean electronics and petrochemicals conglomerate. ...

The WirelessHD (WiHD) standard will allow for uncompressed, digital transmission of HD video and audio signals, essentially making it equivalent, in theory, to wireless HDMI. The specification has been architected and optimized for wireless display connectivity, achieving in its first generation implementation high-speed rates from 2 Gbps to 5 Gbps for the CE, PC, and portable device segments. Its core technology promotes theoretical data rates as high as 20 Gbps (compared to 10.2-Gbps for HDMI 1.3), permitting it to scale to higher resolutions, color depth, and range. In computer science and information theory, data compression or source coding is the process of encoding information using fewer bits (or other information-bearing units) than an unencoded representation would use through use of specific encoding schemes. ... The High-Definition Multi-media Interface (HDMI) is an industry-supported, uncompressed, all-digital audio/video interface. ...

The signal will operate on the 60GHz frequency band and apparently will sport the bandwidth required to support both current and future HD signals. The 60-GHz band currently requires line of sight between transmitter and receiver, but this obviously will not suit the real goal of the WiHD, which is to allow components to be tucked away in a cabinet eliminate the tangle of wires that currently mars otherwise elegant looking hang-on-the-wall plasmas and LCDs. The goal range for the first products will be in-room, point-to-point, non line-of-sight (NLOS) at up to 10 meters. A frequence range or frequency band is a range of wave frequencies. ... This article or section does not cite its references or sources. ... In communications and information processing, a transmitter (sometimes abbreviated XMTR) is an object (source) which sends information to an observer (receiver). ... For the device which is a tuner (radio) and a amplifier and/or loudspeaker, see receiver (home stereo). ... A plasma display panel (PDP) is an emissive flat panel display where visible light is created by phosphors excited by a plasma discharge between two flat panels of glass. ... Reflective twisted nematic liquid crystal display. ... Point-to-Point telecommunications is most recently (2003) referenced regarding wireless data communications for Internet or Voice over IP via radio frequencies in the multi-gigahertz range. ... When viewing a scene, as in optics, photography, or even hunting, the line of sight is the straight line between the observer and the target. ...

A ubiquitous wireless HD standard would do much to improve interoperability among devices, and would also expand the capabilities of personal video players, PDAs, and other handheld devices. PDA may stand for: Personal digital assistant, a digital device which can include the functionality of a computer, a cellphone, a music player and a camera Pitch detection algorithm, a mathematical method of finding the pitch of a signal Public display of affection, an area of study within social psychology...
