This should do what you are looking for. http://www.ramelectronics.net/html/PC-TV_video.html Keith http://www.doubleblackdesign.com

I tried it for work but whether the old building or too many walls but I couldn't get a clear picture from it at only 20 feet away.> > Keith > http://www.doubleblackdesign.com >-- Jethro[AGHL] aka Phat_Jethro Reply Email: jethro86 (at) gmail (dot) com

These things are rather limited. Their primary focus is for presentations that mostly consist of static and/or low-details lides.

Not usable to work with for a longer duration. Example: 1280x1024@60Hz with 24 bit color requires 3*1280*1024*60 Bytes = 230MB/s to be transferred for losless video transfer. Compression can not solve that for all content. Also this will require roughly 2.3GHz Bandwidth (!) to transfer wirelessly. Currently, there is no large enough available space in the RF spectrum for this. Arno

Which happens to not be available. There is no way to beat Shannon. Arno

See http://www.analog.com/en/press/0,2890,3%255F%255F72455,00.html the abstract at http://ieeexplore.ieee.org/Xplore/login.jsp?url=/iel5/10651/33618/01598300.pdf?arnumber=1598300 and the Wireless Telegraphy (Ultra-Wideband Equipment) (Exemption) Regulations 2007 (No. 2084) at [Ofcom (UK)] http://www.ofcom.org.uk/consult/condocs/uwb_exemption/statement/ . Though compression does not 'beat Shannon', it IS the basis of getting HDTV over the airwaves (and very soon to be the ONLY way to get TV over the airwaves in most countries.)

Now, I'm not saying that a 300 buck wireless adapter will give those results, because for the most part they won't, but bandwidth isn't the real obstacle--802.11g has almost ten times the bandwidth of HDTV. -- -- --John to email, dial "usenet" and validate (was jclarke at eye bee em dot net)
