The Secret to Great HD

With so many formats and resolutions on the market, good video processing is key to watching the very best picture.

Video processors are, in essence, the unsung heroes of our home theaters. They aren’t touted or explained much beyond some spiffy-sounding name in a spec sheet. And most people have no idea what they actually do. But they are essential to enjoying video today.



Video processing has a lot to do with the quality of an image displayed on a TV or video display. Video processors are found in TVs, DVD players, audio/video receivers, computer displays and external video processors. The reason video processors are so important is that there are so many different formats and resolutions of video available today, and your DVD player, TV and audio/video receiver need to be in sync with what the video is, where it’s coming from, where it’s going and what it needs to be in the end.

What They Do
One of the biggest tasks of a TV’s video processor is to convert an incoming video signal, say that of a 1080i-resolution HDTV show, to the TV’s native 720p resolution, or vice versa. A higher-resolution “Full HD” 1080p set will “upconvert” the lower-resolution 720p and 1080i signals to its higher resolution.
