Chips are here, but wireless HDMI still out of sight

A chipset promising to allow users to send high definition (HD) video wirelessly throughout the home faces hurdles in the market due to competing technology standards, market researcher Gartner Inc. said Monday. Tzero Technologies, Inc. announced a new chipset earlier this month called ZeroWire, which can carry HD video wirelessly between devices, therefore eliminating the need for HDMI (High Definition Multimedia Interface) cables. The chips can also stream HD signals through coaxial cable, the wires that carry cable TV to many U.S. homes. Any device outside the range of the wireless signal can use the coaxial cable connection instead. The technology was designed to make sure people didn't have to tear open walls to run new cables capable of carrying HD signals, instead making use of existing wires.
