It's funny how everything old is new again. Forty years ago, you might have watched from the backyard as Dad carefully climbed up a ladder to the roof, strapped a bracket onto the chimney, and attached a large T-shaped television antenna so that you could watch those glorious black-and-white (and sometimes color) images from I Love Lucy, Bonanza, The Wonderful World of Disney, Gunsmoke, and other TV programs of that era.

It started out innocently enough, back in January 2000. ABC had concluded a season of Monday Night Football broadcasts in their 720p HDTV format and was putting the icing on the cake with an HD telecast of Super Bowl XXXIV from Atlanta, Georgia. Since I had watched a few of the MNF games in HD, I decided to set up a front projector and an HD monitor and invite some friends and neighbors over to give 'em a taste of sports in high definition. The game turned out to be a big hit. Over 30 folks attended and marveled at the widescreen images from my Sony VPL-VW10HT projector and Princeton AF3.0HD monitor. Never mind that I had to jury-rig an antenna on my rear deck and run coaxial cable into my basement to feed a single Panasonic set-top tuner, then use a video-distribution amplifier to run two component video feeds into my living room and my basement theater. Everyone was amazed at the picture quality and gorged themselves on a feast of wings, subs, pizza, chips, dip, and assorted desserts.

Key Digital Systems (KDS) is no stranger to the world of video signal processing. They've been manufacturing video scalers for several years, including some models that had more functions than a Swiss army knife.

It was easy to be overwhelmed with all the plasma and LCD flat-panel displays at CES 2005. But upon closer inspection, there were a few clear trends and some truly significant advances in technology.
