WirelessHD 1.0 specification moves us one step closer to wire-free home theaters

High definition programming is a great thing for gamers and TV watchers as it allows for much better image quality and better sound. The problem, however, that is always associated with home theater is the mass of wires and cables that go along with most setups.

The WirelessHD 1.0 specification was ratified today. WirelessHD is comprised of a group of companies including Intel, LG Electronics, Matsushita, NEC, Samsung Electronics, SiBEAM, Sony Corp., and Toshiba Corp.

DailyTech first reported on WirelessHD in October of 2006 when it was first announced. This new WirelessHD 1.0 standard takes advantage of unlicensed 60 GHz frequencies to transmit high definition signals from game consoles, cable boxes, DVR, camcorders and other devices to a HDTV for display.

The Motion Picture Association of America (MPAA) said it will work with the WirelessHD group to ensure protected high definition broadcasts are secured during transmission. Jim Williams, Senior Vice President and Chief Technology Officer for the Motion MPAA said in a statement, “The major motion picture studios are actively engaged in the development of innovative new solutions that give consumers greater flexibility and more choices for how and where they access and enjoy movies and television shows.”

The completion of the WirelessHD 1.0 specification will allow manufacturers to focus on the product design portion of product development without fear that products won’t be interoperable so long as the manufacturer follows the WirelessHD 1.0 framework. WirelessHD also has begun the next phase of creating a logo for consumers to easily tell when products using the specification are interoperable along with compliance and test programs.

The frequency sounds like a bad idea

They note that they are going to use the "unlicensed 60Ghz frequency", but that is probably a bad idea.

http://en.wikipedia.org/wiki/Extremely_high_freque...

note at the top of this Wikipedia article, it notes that "signals in the 57-64 GHz region are subject to a resonance of the oxygen molecule and are severely attenuated". I think this would cause significant issues.

From the same article:
quote:
the 60 GHz band can be used for unlicensed short range (1.7 km) data links with data throughputs up to 2.5 Gbit/s (gigabits per second).

Unless your DVD player is 2km from your TV, it's not a problem.

So can you steal the signal from your neighbors house? Oh the new way to steal cable!

You may, somehow. Either way you will not be stealing cable.

This format has already failed. You read it right here.

2.5Gb/s - the most basic HDMI 1.0 has double the bandwidth, so this is DOA, especially since by the time this gets out HDMI 1.3 will be maxed out with TrueHD and multiple uncompressed audio streams.

Yes, selection for this kind of purpose is intentional (as are uses of frequencies near water resonances like in microwave ovens and other services). Cuts down on interference between users that are close together.
