Building an HDTV Without Wires

Sick of all those cables tangled behind your TV or entertainment center? So are two companies that demonstrated products to wirelessly beam high-definition video and audio to TVs at this year’s Consumer Electronics Show. Pulse-Link is creating far-reaching signals, while SiBeam’s system can stream the highest quality HD video. The first products should hit the market by year’s end, reports Technology Review.

SiBeam’s technology includes beam steering to keep video streaming seamlessly, so if a signal is interrupted by a person or an object blocking it, it gets automatically rerouted almost instantly. Pulse-Link plans to release products by the end of 2008, and SiBeam in 2009,  but an industry analyst warns they’ll start out expensive and probably only filter down to cheaper systems a few years later—depending on consumer response.
