Performance LowdownPutting the CableCARD through its paces, I timed a channel change using the up/down control on the TV's remote. (You can also use the numeric keypad for direct channel selection.) It took 2 to 3 seconds to get picture and sound for both standard- and high-definition digital cable channels, but that was no more than with the Scientific Atlanta 4200 HD cable box. I left the box connected to the TV so I could compare the picture quality on standard-def channels using CableCARD with that delivered by the component-video output of the Scientific Atlanta box. The all-digital CableCARD picture was clearer. High-def programs downconverted to enhanced definition, meaning 480p (progressive-scan) format, also looked great through either the CableCARD or the box.

One nice side benefit of CableCARD is that it freed up the TV's single HDMI (High Definition Multimedia Interface) input for other gear - like a DVD player equipped with an HDMI or DVI (Digital Visual Interface) output. I didn't have such a player on hand, so I used an adapter to connect the cable box's DVI output to the TV's HDMI input and conducted another informal comparison. The CableCARD image was again slightly clearer than the image from the box.

The Bottom LineCableCARD delivers on its promise. It lets you use your TV's remote control for all cable and over-the-air programs, it frees up an input that would otherwise be connected to a cable box, it can provide excellent picture quality, and it may even save you a little money. Unless you just can't live without video on demand, CableCARD is an option well worth considering, but you'll have to request it from your cable company. And don't let 'em talk you out of it!
