Today we'll show you how to make a DIY video scaler to get the most out of your HDTV. Videophiles
have been using dedicated video scalers to improve the picture quality on high end displays for years. We'll use free
software and an inexpensive tuner card in our HTPC to scale and de-interlace regular television to look great on your
HDTV. Click on to find out how in today's How-To!
HDTVs are built to display HD material, but SD television signals were designed for CRT television sets.
While most HDTVs have on-board signal processing for viewing normal television, it's often a compromise of quality and
cost.
Dscaler is free software that turns a normal
PC into a very high end video scaler. NTSC and PAL video are both delivered in interlaced format -- in a nutshell, half
of each video frame is drawn at a time, NTSC drawing the screen 60 times each second, but delivering 30 frames per
second. We'll use Dscaler to grab the incoming television signal, de-interlace it and scale it for our display. (In our
case, a projector with a 103 inch wide screen.) While this How-To covers using windows software, die-hard
linux fans should check out ffdshow at http://ffdshow.sourceforge.net.
