New Technology TV

There have been a lot of different ways to get your TV over the years, but Comcast has done some things lately that make cable TV a great choice. Despite all of the propaganda about satellite TV being better than cable TV and the confusion over things like the nationwide transition to digital TV, cable TV from Comcast has turned out to be a great alternative for the vast majority of families!

While Comcast has implemented many technological advancements over the years, the most important one has been digital TV. Digital TV delivers more total channels and better picture and sound quality than the older analog transmission format. This is true even when digital TV and analog TV are transmitted side by side over coaxial cables. The thing is that just because cables are buried underground that doesn't make them completely immune to interference and interference is what makes just about any analog picture look slightly fuzzy and makes the sound less than ideally clear. The beauty of digital TV is that with a digital signal, the interference can be cleaned out by the digital cable TV receiver so that the picture and sound are as good as that of the native recording!

On top of the fact that Comcast's digital TV signal provides a really clear picture and sound quality, it also allows Comcast to deliver more total channels. You see there are a lot of things that can be done with digital technology that can't be done with analog technology and that's because digital TV is really just computer data being transmitted over the cable. That computer data is translated back into TV by the digital receiver. Since digital TV is really just computer data, that means that it can be compressed for more efficient use of bandwidth and the more efficiently bandwidth is used the more channels can be transmitted over a cable (which has finite bandwidth) all at the same time! This has allowed Comcast to increase the number of channels that it offers far beyond the eighty to ninety channel limit that plagued the cable TV industry back in the nineteen nineties. In fact with programming packages reaching up to three hundred channels in size, Comcast is the match of any other TV service provider in existence.

One kind of technology that Comcast is in a good position to implement- and in fact has been implementing for quite some time- is HDTV. HDTV is a newer TV format that's designed to duplicate the experience of a big movie theater for any kind of TV programming in the private home. HDTV programming is provided through HDTV channels which Comcast is constantly adding to its lineup of channels. The thing is that HDTV channels require up to ten times the bandwidth of a normal TV channel, which has made it tough for many TV service providers to implement. Comcast is on track to be able to deliver HDTV channels as they become available thanks to the clever use of bandwidth managing technology.

As you can see, Comcast goes to great lengths to use the latest technology to deliver great TV.
