Up to the present, all 3D HDTVs have used active shutter glasses, and most still do. The two separate 3D images—one for each eye and each of them full 1920-by-1080 resolution—flash on the screen in sequence. Active shutter glasses are triggered by an IR signal generated by the 3DTV (or a separate transmitter attached to it). To isolate the 3D images to their respective eyes, the glasses alternately open and close each eyepiece. The alternating is rapid enough that even though the two pictures are displaced in time, the brain fuses them together and sees them as a single 3D image.

If you checked into our website this week (and of course you did, or you wouldn't be reading this!) you've noticed a whole new look. Access to you favorite sections will be easier, thanks to a more detailed top line. Loading time—we anticipate—will be faster. And, most important—there's a whole new layer of content.

It's no secret that the original DVD release of Titanic—about a zillion years ago in DVD time—was a technical dud. Oh, it looked okay, and the excitement of actually being able to put it on your very own shelf to watch whenever you wanted kept the disappointment to a low simmer. But it was released during the period when studios were just beginning to adopt the anamorphic or "enhanced for widescreen" format. Unfortunately, Titanic was not a beneficiary of that superior technology. As ordinary letterbox transfers go, it was among the better ones. But it wasn't what it should have been.

So now we have a single HD disc format. Hallelujah. No more excuses for sitting on the fence. No more "my upconverted DVDs look almost like high definition" claptrap. The clouds will part, angelic choirs will sing, and…oops, wrong blog.
