LG, Panasonic, NEC, Samsung, LTD, SiBEAM, Sony and Toshiba are working as a special interest group called WirelessHD to develop a specification for a wireless high-definition digital interface (WirelessHD or WiHD).
The WiHD is intended to enable high-definition audio video (A/V) streaming and high-speed content transmission for consumer electronics (CE) devices. In addition to actively promoting the new format throughout the industry, WirelessHD will present the format available for adoption as soon as the specifications are completed, in Spring 2007.
The first iteration of the standard will offer bandwidth of between 2Gbits/sec and 5Gbits/sec, though the core technology allows for a theoretical maximum of up to 20Gbits/sec.
WirelessHD, which intends to specify the unlicensed, globally available 60 GHz frequency band, will enable wireless uncompressed high-definition, high-quality video and data transmission and is first targeted to be built into HDTV's as well as a wide range of audio video (A/V) devices, both fixed location and portable.
"The availability of high-definition wireless connections stands to eliminate the morass of cables, switches and other complexities traditionally needed to support the wide variety of devices consumers have and will continue to buy, such as HDTVs, HD disc players, digital video cameras and game consoles. With high-definition wireless links, media streaming and transmission from any source to any display or recorder is dramatically simplified by removing the need for a hard-wired connection. WirelessHD will provide a high-speed wireless digital interface that will enable customers to simply connect, play, transmit and port their HD content in a secure manner," stated John Marshall, Chairman of WirelessHD.
The key characteristics and focal technologies include:
- High interoperability supported by major CE device manufacturers
- Uncompressed HD video, audio and data transmission, scaleable to future high-definition A/V formats
- High-speed wireless, multi-gigabit technology in the unlicensed 60 GHz band
Smart antenna technology to overcome line-of-sight constraints of 60 GHz
- Secure communications
- Device control for simple operation of consumer electronics products
- Error protection, framing and timing control techniques for a quality consumer experience
"After its launch, WirelessHD has great potential to be adopted rapidly in the consumer electronics segment. WirelessHD should first appear in adapter products, followed by digital televisions and projectors, DVD players, and set-top boxes. Other potential markets include game consoles and portable devices," said O'Rourke of In-Stat/MDR.
