The difference between Comcast High-Speed Internet and DSL is primarily that High-Speed Internet is a full-spectrum broadband solution while the performance and quality of DSL is reliant upon location and limited technology. DSL travels over voice lines while Comcast High-Speed Internet travels over cable. The closer a DSL subscriber is to its Central Office (CO), the better the quality of the connection. Unfortunately, the further away from the CO a subscriber is, the more degradation there will be. This is not an issue with the Comcast network, which has earned a reliability factor of 99%.

dditionally, Comcast technicians continue upgrading and creating exciting new amenities, such as The Fan and The Assistant. Online storage, personal email and web space are part of the suite. Special offers from the Comcast Photo Center complement the package. Bonus features include a broadband home page and remote access to email. Customer experience is further advanced with fresh Comcast content and support tools. Comcast customers can order service both online and by telephone.

Online information centers are connected to regional data centers through Comcast’s enhanced High-Speed network. Data reaches surfers – traveling from regional to local neighborhood hubs. The Comcast network optimizes data through cached websites, which is the key in eliminating performance degradation. With Comcast High-Speed Internet, there is no battling for Local ISP connections and no bandwidth pooling.

Xfinity TV

What exactly is Comcast Digital Cable?

Comcast Digital TV uses compressed signals to bring you superior picture and sound quality without the need for a bulky dish or antenna. It allows you to experience a vast amount of programming and viewing control, which translates into the best television value possible.

How is Digital TV transmitted through my cable lines?

Digital TV works like this: your television picture is sort of like a jigsaw puzzle; the puzzle is broken up into individual puzzle pieces in order to fit through cable lines, and is then reassembled into the original picture when it reaches your home. Breaking the picture up into these smaller pieces allows a vast amount of channels to fit through the cable lines and into your home.

Does every TV in my home need a separate cable box?

Yes. If you want each television in your home to have access to the full line of Digital TV channels, you will need a separate box for each television.

However, it is possible to watch a limited amount of channels without a cable box.

Do I need a Digital Television to get digital cable channels?

No. Your Comcast Cable service includes a Digital TV box that allows your television to receive the digital signal. Thanks to Comcast, you can continue to enjoy your current television without the expense of a new digital version.

What’s the difference between Digital TV and satellite service?

Snow, rain, high winds and even dense cloud cover can reduce or even interrupt a satellite broadcast. Digital Cable service is not prone to interruption from these conditions. With Comcast, you will receive all of your local channels and more. Satellite services only provide local channels in a few dozen major cities around the nation. Satellite systems age and customers must pay for the upgrades. With Digital Cable, you will never have to pay for new equipment if older equipment becomes outdated. Plus, you don’t need to install unattractive, bulky dishes outside of your home to receive your TV signal.

Do I have to have a Comcast Digital TV Terminal to receive Premium channels?

The broadcast digital TV transition was mandated by the Federal government to transfer all broadcast television signals from analog to digital format on June 12, 2009. If you are a subscriber to Comcast Cable, the Broadcast Digital Transition will not affect you.

How can I tell if I already have a digital TV?

Look for a label that says “Digital Receiver,” “Digital Tuner,” “DTV,” “ATSC,” or “HDTV.” If your TV has any of these labels, it is digital and you will not need a digital-to-analog converter box. You may still need an antenna, though, if you are not connected to an outside source such as Comcast. Remember, the transition will not affect your televisions if they are connected to Comcast cable.

Will I have to buy a High-Definition TV (HDTV) in order to watch digital broadcast television?

No, you will not need a high definition television (HDTV) in order to watch digital broadcast television. High-definition is just one type of digital signal.
