Comcast provides a mixture of analog, digital, and HDTV channels. For a $5 upcharge you can get a limited amount of HD programming through Comcast cable. Current HDTV channels include PBS, ABC, ESPN-HD, and NBC.

These HD channels are transmitted as separate channels in the 80 to 90 range; the same programming can typically be watched on their corresponding standard analog channels. You can pay more to receive the premium HBO or Showtime packages. Confirm with Comcast EXACTLY which channels they broadcast in HD so you won’t be disappointed to find your favorite shows are only transmitted in a non-HD format.

To receive the Comcast HD programming you need a set top box provided by Comcast to decode the signals from Comcast. The Comcast hardware is really very good and includes component video and digital audio outputs. Unfortunately most of the standard analog channels are broadcast in mono.
