1080i 1080p
1080p HDTV
You may know that 1080i refers to 1080 lines of vertical resolution interlaced. This means that instead of 30 frames a second, the TV displays 60 fields per second, where each field contains alternate lines of the picture. Because the fields are refreshed so quickly, your brain interprets the signal as 30 full frames per second. 720p means 720 vertical lines of progressive scan video where every frame of the signal is displayed in its entirety, giving a higher-quality, film-like appearance to the picture. Most HDTVs or HDTV-ready TVs support either 720p or both 1080i and 720p, very few support 1080p HDTV. Part of the reason for this is that very few broadcasters want to broadcast 1080p signals. The reason for that is that 1080p requires significantly higher bandwidth than either 1080i or 720p. And for broadcasters, bandwidth is a precious commodity. Using up more bandwidth for one signal means that there is less room for other channels. So in many cases, opting for a 1080p signal would mean dropping or degrading other channels. Is 1080p HDTV important? Well, yes and no. Not all video footage benefits greatly from progressive scan. Sports broadcasts and action movies look better at 720p than 1080i because there is lots of fast movement and the interlacing in 1080i is sometimes noticeable, reducing the quality of the picture. Movies and TV shows where there is not a great deal of fast action look better at 1080i than 720p because the higher resolution has a greater impact on quality than the progressive scan, which has little effect where there is only a small difference in the image between frames. So, while 1080p HDTV is the best of both worlds, the cost in terms of bandwidth, is very high compared to the benefit for most people most of the time.

After a faltering start, Blu-ray has well and truly come of age. It was always meant to be the successor to DVD and now that the discs and players have become almost commodity items in the supermarket, there?s really no excuse to put off that upgrade into the world of high-definition entertainment. In fact, the players themselves have become much more than just HD disc spinners, as these feature-laden machines prove. As well as dipping to tantalizingly low price points, these budget boxes will also juggle your other digital media files through USB ports, or stream them from your PC. And the Ethernet ports, that were originally intended just for grabbing BD-Live content, now invite all manner of clever online widgets, including BBC iPlayer and LoveFilm downloads. Of course, different brands are taking different approaches to Blu-ray hardware, so consumer options vary quite a lot even at the low end of the market...

28 Jul 2010 at 2:33am  Will Panasonic?s first domestic 3D camcorder change the way people think about home 3D? I'd say it's highly likely, after having had an early hands-on with this remarkable product. After just a few minutes shooting it's easy to see its creative potential.
And not only does it open up a whole new world of opportunities for home video enthusiasts, it also removes 3DTV's dependence on commercially produced software (which remains nigh on unavailable).
The HDC-SDT750 is an adaptation of the previously available HS700, but with newly-minted removable 3D lens appendage. It records 3D video using the side-by-side technique (960 x 1080), so footage lacks the resolution possible from 3D Blu-ray, but the clarity is more than enough to create an engaging 3D viewing experience. The camera connects directly to your 3DTV over HDMI. Most TVs will auto sense its 3D mode, but some users may need to manually select side-by-side from their set?s 3D menu.   An issue of balance
Hardcore videographers may find the SDT750 a bit of a handful. The 3D lens attachment itself is rather large, and I found that this significantly changes the balance of the camera. However, you quickly adapt and end up cradling the unit to restore equilibrium.
Moving from 2D to 3D mode, perhaps the biggest consequence of the bolt-on 3D lens is that you lose the ability to zoom the image. The x12 zoom mode is disabled, frustrating the natural urge to close in on your subject. The fixed 3D lens assembly also means that you do not have any creative control over the level of image depth in the images. On the plus side, the thing couldn?t be easier to use. It truly is a point-and-shoot 3D experience. Consequently, for many the opportunity to record ?Baby?s first steps? or the family holiday in 3D will prove too attractive to pass by. Yours for £1,300
Naturally, the camera also shoots 2D Full HD in AVCHD format; image clarity is pristine, thanks to a 3MOS sensor and Leica Dicomar lens. The camcorder also has a neat 5.1 audio recording mode. Five microphones are used to create a standard L/C/R/ and surround sound stage. Helpfully, the HDC-SDT750 will ship with (PC only) software that allows users to edit footage in native 3D mode. The camera is expected to sell for £1,300 when it goes on sale this Autumn. For more on Panasonic's 3D plans click here.

28 Jul 2010 at 2:09am  Speaking at the launch of the revolutionary new HDC-SDT750 3D camcorder, European CEO Laurent Abadie says that the roll-out of 3D was exceeding Panasonic?s expectations. In an interview over at 3D Radar, Abadie says Panasonic?s mission is ?to think bigger ? and do bigger!?
?Demand for the VT20 50in plasma is far, far, far above our highest expectation,? he says. ?We introduced it in April this year, but demand has been three times higher than availability. Which was a pity, because in many stores the product was sold out. Our mission now is to revise our plan. I really believe that 3D is a strong augment for consumers today. After the shock of James Cameron?s Avatar, last December, 3D became a trigger for everything: for gaming, for movies, for broadcast stations. 3D is everywhere in the world, not just Europe, it?s a global revolution.?
 More 3D coming
While Abadie concedes that Panasonic?s 3D range has been small, that will all change at the 2010 IFA Tech Expo. ?You will see a lot of new products. Following the launch of our 65in 3D plasma model, we will have 46in and 42in models?a full range. We will also show at IFA a 153in 4K2K 3D model.? Abadie says that the giant screen is already commercially available, and offers me the chance to place an order. ?The price is £400,000,? he teases ?and we already have orders. It?s incredible.? All of the brand?s 2010 3D TVs look likely to remain plasmas. While the company has made a significant investment in LCD, with a new facility at Himeje (?it?s one of the biggest in the world.?), it maintains that plasma presents the best technical solution for Home 3D. ?From the engineering side, we really believe that plasma is much better (than LCD). The way the images are managed and the lack of crosstalk. This is a big discussion internally, but our key people really feel that plasma for sure is the best technology. This is so visible with the 50in. With 3D you have to be careful. If images have crosstalk you feel that there is something? wrong with the image, it can be tiring to watch even if it is not that visible.?
