Almost everyone has heard of the "Home Theater PC" (HTPC) and people are rapidly becoming familiar with media center extenders that can play music, pictures and video on your TV. But there's one segment that is not getting just as much attention, and in my opinion is the better of all of them. Intel Wireless Display (WiDi) technology has been out for over annually, and is also now in the second generation. With WiDi, you do not need an additional computer mounted on your TV, you do not need a server streaming to some third party media center extender, all you need is your laptop. WiDi is hardware accelerated wireless streaming of one's computer's display and sound to the TV. - Widi TV
WiDi is primarily designed for laptop users as it permits them to sit on the couch and employ their TV as his or her laptop screen. Various ways of doing this have been around for a long time, and possess usually involved either plugging your laptop into the TV or streaming through a media center extender box. Plugging your laptop in is a problem, as well as a long cable. Media streamers and media center extenders are often slow, expensive, require another computer to act being a server, and can only do limited things. There's also several alternative party solutions for streaming video towards the TV, nevertheless they typically involve SW transcoding which can be CPU intensive. This limits the capabilities with the video stream as well as bogging down the laptop in the act.
What's great about WiDi is the fact that all you have to do is push some control around the laptop and the display is automatically transmitted towards the TV. It's quick and simple. Since this is accomplished mainly in hardware, without software processing, the CPU is still largely free to do with when you please. So you can browse the net, watch free movies online, read a document, or whatever else you do using the pc from the couch using the TV and residential entertainment system. WiDi 2.0 will quickly support full Dolby 5.1 Surround too, something many media center extenders lack. But that the separate receiver box is essential about the TV side to get the signal, and so they usually go for around $100. This is still less money than a media streamer while offering much more flexibility. Additionally there is a little bit of lag between your movements on the laptop screen and the movements around the TV. This will make it difficult to play certain video games. If WiDi technology gains popularity, you will have ample incentive for Intel to handle the lag issue in future versions.
I think WiDi technologies are better than media streamers and HTPC (unless you are recording tv with all the latter). It's simpler plus more versatile than a media streamer, and a lot cheaper plus more efficient when compared to a HTPC. Use it to try out your ripped DVDs about the TV, amongst other things.
And so i was these sites are ready to create this article about how great WiDi technologies are, after which along comes WHDI. WHDI corrects the shortcomings of WiDi and adds a huge key advantage. The fundamental premise is identical, wireless transmission of one's laptop's screen towards the TV together with audio. While WiDi offers a nice integrated solution using the existing wireless contribute a laptop, the lag because of hardware compression of the video stream makes winning contests about the TV from the computer virtually impossible. WHDI instead has an uncompressed, lag free video stream from another device that attaches to the USB and HDMI ports of the laptop. No special laptop hardware is required, and it doesn't even really need to be considered a laptop whatsoever. Anything with a USB and HDMI connection will work, Tablets, cell phones, anything. Since there is without any lag, anything is currently possible, even games. Up to I wanted to like WiDi, there is just no navigating around the fact WHDI supplies a better solution
WHDI products are right now beginning to hit the businesses, in addition to WIDI 2.0 products in the future. It will be interesting to determine how WIDI 2.0 based hardware competes with WHDI. Current WHDI offerings from HP and Asus are large and hulking and would be a pain to use with the laptop about the couch. But there are a bunch of products launching in the future that pack everything right into a simple stick that plugs into the medial side of the computer, rivaling the convenience of WIDI's integrated solution. - Widi TV
