How many of you would like to get an LCD TV for Christmas? A lot, I bet. How many of you know that the Sony Bravia LCD TVs are powered by Linux? A lot fewer, I guess.

LCD TVs have a lot of pixels. When displaying a normal-resolution programme (say from the MBC), the TV must use extremely complex image processing algorithms to generate the missing pixels. For example:

• SECAM @ 720 x 576 = 414,720 pixels every 1/25 of a second (I’m simplifying…)
• HDTV @ 1920 x 1080 = 2,073,600 pixels every 1/25 of a second

So the TV must digitally create 5 times as many pixels as in the original frame 25 times per second. As you can easily guess, this requires a lot of horsepower hence the use of a powerful computer inside the TV. Sony has chosen Linux to power that computer (specifically Linux kernel 2.6.11)
