WHDI (Wireless High-Def Interface) is being worked out now by a group of world’s largest consumer electronics companies, for standardizing this technology to achieve better interoperability among those future devices produced by them.
The WHDI allows the high-def video (high-res and uncompressed) to be transmitted in the air wirelessly from the sources to various players. Such as HD video can be transmitted wirelessly from your Blu-Ray player or video cam onto your setop box, TiVO, PC or vise versa, and the HD video signals are well transmitted within the 100-feet range.
The future products of those companies participating in working out the interoperability, will get a logo of WHDI on their products, which clearly indicates it’s a product that is compatible with other WHDI-enabled devices. A variety of these products are expected to surface in the market by 2009.
The WHDI is the brainchild of Amimon, an Israeli company, which has figured out how high-res video can be transmitted wirelessly without losing quality, with no noise added and no delay after you press the “play” button. And the great part is the technology will be commonly available at highly affordable cost. Some products that have demonstrated WHDI include a TV from Sharpe, a set-top pair from Belkin, and also Sony had demoed it at CES 2008.
Consumer electronics giants, Sony, Samsung, Motorola, Hitachi, and Sharp are now striving to build the wireless 1080p transceivers into their consumer electronics devices. Once they’re got it done, HDTV pictures can be shot around wirelessly from sources such as PC, Blu-ray and DVD players etc to a projector or HDTV for display, as along as they’re within the 100-feet distance.
Those who’ve witnessed the demo of the HDTV claim that the wirelessly-transmitted HDTV video clip shows no difference from the wired HDMI video. They were compared side-by-side on two screens, with one was wired and the other wireless, and are claimed indistinguishable between the two. And the latest tech from Amimon that boasts 1080p/60 frames-per-second resolution shows a much better result. Some more, the company is working on a 2nd-gen of the chip which would be ready end of this year and show much higher video quality.
What about the price? According to the engineer of the Israel firm, WHDI-equipped devices will add around only $100 for each device. And the consortium is now working hard to ensure that WHDI product will have wider interoperability. Once the chip’s been installed into over a million of devices, the cost per chipset will drop to $10 only for each device.
In about two years’ time, plenty of these WHDI-equipped devices will fill up your living space – to have your Blu-ray player to shoot HD video wirelessly onto your laptop for watching will no more be a dream.
