Question

Do I need to purchase a digital or high-definition TV?

Answer

No, it is not required to have a digital or hi-definition (HD) TV to enjoy the new features.  Your TV service will be the same as it has been, except it likely will appear sharper, have more vibrant colors, and improved audio quality.  A HD TV is necessary to fully experience HD quality programming.  Without a HD TV, the customer may not notice a difference between standard-definition (SD) and HD channels.
