The WirelessHD consortium has completed its first specification for high-definition (HD) baseband video transmission at 60GHz.

The groupcomprised of Intel Corp., LG Electronics Inc., Matsushita Electric Industrial Co. Ltd, NEC Corp., Samsung Electronics Co Ltd, Sibeam Inc., Sony Corp. and Toshiba Corp.,is planning to outline the 1.0 format to adopters over the next few weeks, beginning with discussions at the this week's Consumer Electronics Show (CES) in Las Vegas .

WirelessHD is a wireless HD digital interface standard operating in the 60GHz frequency band and represents the first consumer application of 60GHz technology. It is suitable for a wide range of devices including TVs, HD disc players, STBs, camcorders, gaming consoles, adapter products and other source devices.

The spec was expected to be announced last September, including the methods for addressing file transfers between camcorders, cameras, DVD recorders and TVs.

Gigabit wireless technology chip startup SiBeam revealed some details of the 60GHz technology that it and partners in the WirelessHD consortium planned to deploy last June. SiBeam said it has developed both successful transmit and receiver 60GHz chipsets in CMOS as far back as 2005.

"With the completion of the WirelessHD specification, consumer electronics manufacturers can focus on their WirelessHD-based product development efforts," said John Marshall, chairman of WirelessHD. "This important industry initiative will change the way manufacturers develop and market devices, as well as reshape how consumers interface with these products."

WirelessHD's 4Gbit/s digital interface and secure content protection technology ensures that future products developed based on the specification will provide consumers with a secure, quick and easy way to connect, play, transmit and port their HD content among a wide range of devices. The specification also includes provisions for universal remote control of all WirelessHD compliant devices.

With content protection a high priority in the specification, the Motion Picture Association of America has agreed to work with the special interest group to protect film copyrights during wireless in-room transmission.

The WirelessHD group has also started development of a compliance program and associated test specification plan, for which it has garnered support from major test equipment manufacturers.
