High Definition (HD)If you're particularly interested in a High Definition picture (around three times better quality than DVD), you'll need a High Definition set top box. You can view High Definition on any TV, but to make the most of its superior quality, consider a TV with a high definition display.
WidescreenBecause the widescreen picture is a different size to the regular TV picture, it's best to have a widescreen TV with your digital set top box. You can view widescreen presentaions on regular 4:3 TVs though it will appear in the letterbox format.
