C/Net reports that several leading consumer electronics companies are working together to develop a new standard for transmitting high-definition audio and video signals wirelessly.
The WirelessHD interface would enable high-speed streaming of audio and video content at 60 GHz between televisions, DVD players, games and other portable devices. The group plans to release the specification in spring 2007.
WirelessHD will use unlicensed 60GHz radios to send uncompressed HDTV at 5 gigabits per second at distances of up to 30 feet. It is supported by LG, Matsushita (Panasonic), NEC, Samsung, Sony, Toshiba and semiconductor maker SiBeam, spun off from the Berkeley Wireless Research Center. How that technology will be made available to other chip makers remains to be seen.
While most other wireless audio and video transmissions occur in the 2.4GHz-to-5GHz range, WirelessHD says neither will allow the fast transmition speeds required for high-definition content. The experience will be the same as using a high-definition multimedia interface (HDMI) or digital video interface (DVI) cable says the group.
Up to now, the 60GHz band has been too costly, but breakthroughs in CMOS manufacturing have made it practical for consumers, according to WirelessHD.
WirelessHD will have competition from at least two other wireless approaches, including MIMO-based WiFi (802.11n) at 5.8 GHz and ultra wideband (UWB) technology. Analog Devices plans to use JPEG2000 video-compression on UWB to send HD content between televisions and other computer electronics devices.
