When it comes to audio/video connectivity standards, it
looks as though there is always a revolving door of new technology coming in
and leaving. HDTVs today come packed with composite, component, DVI, VGA, HDMI
and optical out connectors to ensure that we have every possible option covered
when hooking up our various receivers DVD players, gaming consoles and speaker
systems.
A new consortium made up of some of the leading companies in the consumer electronics business is looking to replace that nest
of wires hanging out behind your TV set with wireless technology. The new WirelessHD Interest Group is composed of LG
Electronics Inc., Matsushita Electric Industrial Co., Ltd. (Panasonic), NEC
Corporation, SAMSUNG ELECTRONICS, CO., LTD, SiBEAM, Inc., Sony Corporation and
Toshiba Corporation. Together, the companies are working to implement
WirelessHD to provide wireless transmission of uncompressed A/V transmissions
in the 60 GHz frequency band. John Marshall, Chairman of
the WirelessHD Interest Group, had this to say about the new wireless standard:
"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."
With most of the top consumer electronics manufacturers
onboard -- and with more sure to join within the coming months -- the work now
begins to flesh out the specifics of the wireless standard and to push for
widespread industry support. So far, the WirelessHD Interest Group is focusing
on these aspects of WirelessHD:
- High interoperability supported by major CE device manufacturers
- Uncompressed HD video, audio and data transmission, scalable 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
Specifications for the new standard are expected to be
ratified in the spring of 2007. The technology is expected to be ramp rapidly
with In-Stat commenting that total shipments of devices with high-speed A/V interfaces (wired and wireless) should rise from 60 million units in 2006
to 495 million units by 2009.
