Even as DVI and HDMI were being adopted by video manufacturers as the digital links of choice, one limitation of these connections was already well known: they don't like to be used in long lengths. The generally accepted limit for an unassisted digital video cable of this type is about 5 meters or just over 16 feet, particularly with high-definition sources.

Threatened with eviction from his lifelong home, Carl Fredrickson cuts loose in an unexpected way and sets off on a journey to the South American wilderness he and his late wife had long yearned to visit. Along the way, he picks up a few unwelcome (at first) fellow travelers: Russell, an 8-year-old Wilderness Explorer; Kevin, a rare bird and a key plot McGuffin; and Dug, a talking dog. Carl also runs into his boyhood idol, explorer Charles Muntz, who turns out to be less of a hero than he had long imagined.

Time for a dip in the summer movie pool. My splashing around has so far been limited to Star Trek and Up, but both, in their own ways, are the best of the summer lot so far (as of early June). Yea, I know, it's not even summer yet. But don't tell Hollywood. In any case, I can hardly wait for the Blu-rays of both of these films, sure to be coming to your local video store in the fall.

"Buy any 61-inch or larger Samsung HDTV or any Samsung 1080p HDTV and receive a high definition, upconverting DVD player."

It's hard to fight the notion that an upconverting DVD player works some kind of magic on the lowly, standard definition DVD. I've written about this before, but if recent Internet forum traffic is any indication, the confusion continues.

Toshiba recently issued an update for its second-generation HD DVD players, primarily for the HD-A20 and the HD-XA2. I installed the update on an HD-A20, the middle model in Toshiba's HD DVD lineup (though shortly to be superceded in the launch of a third generation).

Despite all the talk about 4K (or Ultra HD) displays, there are already a bazillion hours of “standard” 2K HD programming out there in videoland. Consumer 4K sources will be slow in coming, and they might well arrive over the Internet. The question remains as to whether or not the inherent data rate limitations of streaming video could dilute or eliminate the supposed benefits of 4K resolution—apart from the marketing hype.

Over the next couple of years, therefore, and assuming that 4K sets take fire in the marketplace, the smart money will be on upconverting 2K sources to 4K. No form of upconverting can add real resolution; genuine Ultra HD starts and ends with 4K resolution. Nevertheless, we expect plenty of action on the 2K to 4K upconversion front. Since consumer 2K is largely (though not entirely) 1920 x 1080 pixels, and consumer 4K is 3840 x 2160, it would appear that such upconversion might simply involve taking the content of each 2K pixel and quadrupling it (with no added enhancement) to fill a 2 x 2 pixel area on the 4K display. But that will gain nothing in subjective resolution, and may actually reduce image quality due to the added processing required. Most upconversion, therefore, will likely include enhancement and/or other digital manipulation, designed to both eliminate possible upconversion losses and better simulate the look of true 4K.

The Vandersteen 3A is a higher-end variation on the theme established by the company's first loudspeaker, the 2C. The latter is still available, though much updated into the current, highly popular 2Ce. A four-way design, the 3A has separate sub-enclosures for each drive unit; the whole affair is covered with a knit grille-cloth "sock" with wood trim end pieces. A rear-mounted metal brace allows the user to vary the tiltback—an important consideration for best performance with this loudspeaker.

Vicoustic USA is a company new to me in the field of acoustic treatment. They offer a wide range of products, including some unique absorbers and diffusers, for that application. Many of them are less expensive, in my experience, than many of the similar devices currently available. They begin as low as $75 each for an approximately 2-foot square panel (but only available in a package of 10), though the prices can escalate rapidly when you get to premium products such as all wood diffusers.

I predicted years ago that we would be downloading music over the Internet long before <I>high quality</I> downloads were possible. That's the state we're in at present. Downloads that offer genuine CD-quality sound (forget about downloads up to SACD or DVD-Audio standards) are still more a promise than a reality.
