Features to Look For ƒ High scanning/HD monitor/HD upgradeable television. These televisions accept the full 1080 interlaced scanning lines (1080i) from an external High Definition receiver or High Definition DIRECTV receiver. They also accept the 480 progressive scanning lines (480p) from progressive output DVD players. In both cases, the picture is vastly more detailed than conventional television, which uses 480 interlaced scanning lines (480i). The difference is dramatic, especially in the larger screen sizes. In big 480i screens, the scanning lines are so large that they can become visible, undermining the sense of reality. In high scanning televisions, the scanning lines blend seamlessly together into a more realistic, more emotionally compelling image. ƒ Digital Reality Creation™ circuitry. High scanning televisions generally boost conventional 480i sources to higher line rates, such as 960i or 480p. Even though the picture resolution does not change, you get a more seamless, more satisfying image on the big screen. A big step up from a line doubler, Sony's family of Digital Reality Creation™ circuits does an even better job. By replacing analog picture patterns with their High Definition digital equivalents, DRC doubles the number of scanning lines and doubles the number of pixels on each line. You get pictures with four times the original picture density-approaching the quality of High Definition! Sony's Digital Reality Creation circuit not only doubles the scanning lines of conventional 480i sources, it also increases the picture density to nearly that of High Definition sources. ƒ CineMotion™ 3-2 reverse conversion is a technology employed in Sony high scanning televisions. It overcomes the problems that can sometimes occur when movie film, which is shot at 24 frames per second, is displayed on progressive scanning televisions, which operate at 60 frames per second. In order to display 60 frames, some televisions take scanning lines from two adjacent movie frames and force-fit them into one television frame. This makes a hash out of any object that's moving on the screen. Vertical edges that should be smooth take on a disturbing, The Sony Guide to Home Theater 25
