Question
Is there a difference between set top boxes?
Answer
The main difference between set top boxes is in their ability to display either standard definition (SD) or high definition (HD) digital television. More sophisticated models have features such as an electronic program guide and let you record programs to an internal hard disk drive or DVD. Whether you choose to have an SD or HD set top box depends on your television. An SD set top box will let you see all the standard definition free-to-air digital channels, while an HD box will also let you see the HD channels provided by the free-to-air networks. If you connect an HD set top box to a TV that is not capable of showing programs in high definition, you'll still get the additional channels but without the high definition quality.
