Comcast Makes Continual Upgrades to Cable TV
Cable TV has had a less than stellar reputation in the past, but there are some things that Comcast is doing (and has done) that make cable TV worth looking into again. The most basic thing that Comcast has done was to embrace digital TV technology. This may seem pretty elementary, but it actually has some pretty far reaching implications. For example, using digital TV to transmit TV programming has the benefit of allowing each video stream to be compressed so that it takes up less bandwidth. When each channel takes up less bandwidth, a cable TV company like Comcast can fit more channels over the existing cable infrastructure without having to replace it or add more cables. This compression technology makes Comcast able to provide over three hundred channels, making it at least as good as any satellite TV service.
Another thing that digital TV allows Comcast to do is to provide a better picture. Any time that TV is transmitted it picks up a certain amount of interference. Even if it happens to be transmitted over buried cables, it still picks up the interference of cosmic rays or something. This inevitable interference translates into a fuzzy picture for any video that's been transmitted more than a couple of hundred feet over a cable.
The good thing about digital TV is that a digital cable receiver can tell the difference between interference and the real signal, making it easy to clean all of that picture ruining crud out of the signal. The same thing works for sound too.
Digital TV also allows companies like Comcast to provide access to other technologies as well. For example, it's now possible to provide an interactive on screen program guide with digital TV to allow viewers to see what's available for them to watch at any given time. It even includes descriptions of the TV shows and movies that you have to choose from. This is a great way to keep track of all the hundreds of channels that Comcast no provides. Digital TV also makes parental control software available as well. Parental control software can be programmed to filter out specific types of programming that you may not want your kids to view. Then, before each program comes on, the software will check to see that it meets you criteria before allowing it to be displayed.
Digital TV also forms the basis for higher tech features like HDTV. HDTV is a great new way to watch TV because it provides an even sharper picture than regular digital TV along with a great sound format. Comcast has been especially ambitious about implementing new HDTV channels to the point where it's extremely competitive in the number it offers.
Comcast is taking advantage of digital technology in another way with the implementation of Switched Digital Video. Switched Digital Video is a new technology that will allow Comcast to provide a virtually unlimited number of channels- including HDTV channels- by making even better use of existing bandwidth.
All of these things make Comcast a good alternative for cable TV. - 2361
