Mike: There are two competing technologies on the 3D TV glasses market; active shutter and polarized. Active shutter technology uses infrared or radio frequency to communicate between the TV and the glasses. Signals are sent from the TV, turn the glasses to dark in the left and the right frame and seeing for the alternating left and right images that are displayed on the TV. This creates a stereoscopic 3D image in four [Inaudible] [00:00:30] for each eye. The disadvantage of active shutters are the glasses are bit heavier and these batteries which have to be replaced or recharged every 80 hours or so.

The biggest setback for active shutter technology maybe in the cost which would set you back around 50 to 100 bucks a pair. Its one thing to lose that are more, but it´s not anything to lose a $100 pair of glasses or accidentally sit on them. With polarized technology there is no receiver, so you don’t want to worry about batteries or high cost. If you saw 3D movie in the last couple of years you are probably wheeling them through circularly polarized glasses like these. In this method each frame of the movie is polarized in the clockwise or counter clockwise pattern, so that each lens only sees the corresponding image. The right eye image on the screen will appear dark in contrast to the left lens, but this happens at a high frame rate which is faster than human eye can perceive. Circular polarity is a step up for pass of 3D glasses. In earlier years they use horizontal and vertical polarity, but this create a very limited field of view so if you are watching a movie and you tilted your head you will lose that 3D effect.

The disadvantage of pass of 3D technology is a higher cost in the TV. Since the screens will have to use a polarizing filter and through the pass of glasses you will only get half the resolution in each eye, that’s 540 lines versus 1080. XpanD, the largest supplier of active shutter glasses insists that nearly a 100% of the cost to make TV’s 3D capable is in the glasses. You just need a TV that can display at a high enough refresh rates. This would lower the cost of the TVs and companies like LG are not including glasses with the TV leaving to the customer to purchase their own. Now purchasing glasses separately that might not be such a bad thing, this would offer the customer variety of choices. Imagine getting a pair of designer glasses from Oakley, Gucci or Armani companies are already coming up with designs that range in color and durability and some companies are even offering prescription 3D glasses. Active shutter glasses will range from anywhere from 50 to 250 bucks. For what has been released so far, it looks like you will need to purchase a new TV if you want to experience 3D in your home. We went to CES to see the first line up of 3D TV’s to hit the market. Samsung was among the manufacturers debuting their line up with 3D TVs to be released sometime this year. The UNC9000 series is not only the thinnest LED based LCD TV so far but it comes in iPhone style or mode, you can navigate through their extensive interactive TV.

One of the best features to come out of Samsung’s series of 3D TVs is the auto conversion ships. That means as soon as you get the TV home, you can watch your 2D programs converted into 3D in real time, since [Inaudible] [00:03:30] lack of content available at this time that sounds like a pretty attractive feature. Samsung partnered Real Deed to integrate an active shutter technology but they don’t include the glasses. Sony is one of the few companies that do specify inclusion of the 3D glasses. Their LX900 models range from 40 to 60 inches and include two active shutter glasses. They also include a new feature called intelligent presence sensor which [Inaudible] [00:03:57] when someone is standing too close to the TV, or if the user walks away it will actually dim the TV for you. The XVT pro series by Vizio is using XpanD’s active shutter glasses which use Bluetooth to communicate with the TV, but unfortunately you are going to have to purchase those glasses separately. The pro series features an optional wireless HT My base. At the Toshiba [Inaudible] [00:04:21] ZX900 series which includes a 55 and 65 inch TV equipped with one tier byte of hard drive and WiFi which enables you to transfer media to your TV or view streaming broadcast from Netflix or Pandora.

Toshiba cell processor powers its real time 2D to 3D converters. So users will have some 3D to watch right out of the box. Panasonic is offering a plasma solution with their infinite black pro technology. That’s a filter that minimizes reflective light and its said to have a negative contrast ratio of five million to one. That will be really helpful since the glare seems to kill the 3D effect. Panasonic’s plasma offers optional WiFi with skype calling through the TV and support for streaming content. We also checked out the demo for LG to see their Infinia 3D TVs on display. These TVs using active shutter technology and have an ultra thin one inch depth. Now once you [Inaudible] [00:05:23] on a 3D TV you need something to play your 3D movies on. Movies already on top of that but the first format to deliver four 3D HD which means 10 ADP going to each eye, you don’t have buy a new Blu-ray 3D player to watch this new format unless you have a PS3 in which case you get a free firmware from Sony.

You have another great reason to grab a PS3. The new players will be back that’s compatible with the standard blu-ray movies, but if you want to switch from 3D to 2D on the new format you may not be able to depending on your TV. You might be wondering what kind of cables can deliver 10 ADP to each eye, HDMI of course. In fact, HDMIs create a new standard that will handle 3D TV Ethernet and resolutions of up to 4K x 2K which is what most cinemas use. The Ethernet portion allows for internet enabled device like a DVR to share that connection with the device it´s plugged into like a TV. So the technology is there to deliver this content but when you purchase your 3D TV where you have anything to watch on it when you bring it home?
