Examples of Unique Features You'll Find On A HDTV Rear-Projection Television (Sony)


To help customers evaluate the features they may want in a HDTV wide-screen rear-projection television set, here is an example of the unique features found in Sony's rear-projection set. I own a new Sony 57-inch diagonal HDTV, rear-projection wide-screen television, and I'm impressed with the quality, detail, contrast, and convergence of the HDTV picture. So I thought you might want to check out the hot specs on a Sony HDTV set. Be aware other manufacturers may have similar features but with different copyrighted logos or descriptive titles.

Please note that while these similar helpful circuits may be found in other HDTV rear-projection sets, the descriptive headlines shown below are Sony's trademarks. All descriptions are taken directly from Sony's online spec sheets and have not been edited for any reason.


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.


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!



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, zipper-like texture. And this unwanted artifact happens frequently, occurring on two out of every five video frames! To make matters worse, the problem is not limited to those times when you're watching movies. Most prime-time dramas, music videos and commercials are also shot at 24 frames per second.

That's why CineMotion 3-2 reverse pull-down is so important. It analyzes the picture, identifying the difference between footage shot on interlaced video and footage shot on film. For film footage, the system actually retains the integrity of the original film frames. You'll see a clearer, more stable picture, especially on scenes with movement.


DVI-HDTV interface

This feature enables superb, uncompressed digital-to-digital connection from the set-top box to the television. Your High Definition signal is carried with full picture quality. The connection is also secured by HDCP technology to protect the signal from piracy.
