Cell/B.E. speed makes HD TV prettier: Why are we talking about television? Because the heart of the Toshiba Regza 42ZV555D and 46ZV555D TVs -- the first "upscaling" TVs according to the company -- is the Cell Broadband Engine processor.
What's "upscaling"? HD TVs have something called an upscaler built in -- what it does is convert video that is shot at a different resolution to the screen to fit the screen (if you didn't, you'd get a small picture in the center of a big screen). The upscaling hardware:
- Stretches the picture to fit.
- Applies video processing to make the picture look as good as possible.
- Applies processing to convert standard-definition, interlaced pictures into progressive ones because LCD and plasma TVs can only display a progressive image. (With an interlaced image, you see the odd lines then the even ones; with a progressive image, you see all the lines sweeping left to right at the same time.)
Where does the Cell/B.E. processor come in? Faster processing, better quality.
