How TV Tuners Work

I would venture a guess that many GeekTonic readers own at least one TV tuner for their HTPC – or would like to have one at least.  But if you’re like me, you probably don’t really know much about how those TV Tuners really work.

A very “techy” site I follow called kernellabs focuses on linux, and the audio/video drivers to make media devices work with Linux.  Kernellabs has a great article that crosses over into the engineering side of things and does a great explanation of how tuners work.  It’s a great introduction into how the tuners are built giving you a better understanding of what it takes to work with those drivers.

If you have any interest in the “how it works” side of TV Tuners, this is a great place to start.  Check out the full article:
