What is Comcast Digital Cable?
Comcast Digital Cable is a brand new way for Comcast to deliver television signals to your home. Digital technology enables Comcast to "compress" its signals, thereby providing you with high-quality picture and sound -- all without the dish or unsightly antenna. Convenient access to programming, more value, increased viewing control and a better customer experience are just a few of the benefits you'll enjoy with Comcast Digital Cable.
How does Comcast Digital cable compare to Comcast Basic Cable?
Comcast Digital Cable uses advanced technology to deliver more choice than is available with core analog cable service. Some key benefits of Comcast Digital Cable include:
How does Comcast Digital Cable work?
Imagine your television picture is a jigsaw puzzle broken down into individual pieces, placed in a box, shipped to its final location and put back together again exactly as it was before. That is essentially how digital cable works. And because the picture takes up less space in digital pieces, many more channels can fit through the existing cable system in your town.
Do I need a separate Digital Cable box for every outlet?
No. Many Comcast Digital Cable Customers choose to put a Digital Cable box in one room; others prefer to have one in every room. In rooms that do not have a Digital Cable box, you may not be able to receive all of the channels that you get in the room with the Digital Cable box. The Digital Cable box is required to view any programs ON DEMAND (where available) and premium or pay per-view channels that Comcast offers.
Do I have to buy a Digital TV to receive Comcast Digital Cable?
No. With Comcast Digital Cable you will receive a Digital Cable box that modifies the incoming Digital signal so that it can be viewed with your current TV. With Comcast Digital Cable you will be able to enjoy extended service from your current television, without having to buy a Digital TV.
What is a digital converter box (set-top box)?
A digital converter box (also called a receiver or set-top box) is actually a powerful computer that receives cable input and processes multiple channels into a single frequency so that sound and images can be viewed on your television. That is why your TV must be tuned to channel 3 or 4 in order for the box to work properly. When the digital converter is attached to your TV, you are able to watch digital channels. Not only does it process incoming signals, but it also sends information back to our signal-processing center. This enables our digital customers to enjoy services such as ON DEMAND from Comcast Digital Cable. Since these boxes now do more than "convert" channels to a single frequency, they are also referred to as set-top boxes. They also allow authorized customer TVs to receive all of the cable channels offered by the system.
