Digital Cable TV Has Something for Everyone
Even if a person has a hard time admitting it, everyone watches TV at some time or another. Whether it is just the evening news, or inadvertently catching a few minutes of Saturday morning cartoons with the kids. The influence of television in the American home is an undeniable force.
The reality of watching television these days is that no matter what you are interested in as a viewer, you can probably find a channel or a program that you will enjoy watching thanks to the advances in digital cable TV. Not only does a digital transmission offer superior sound and image clarity over its analog counterpart, subscribing to digital cable TV means access to more channels than ever before. If you are the kind of person who thinks nothing good is ever on television, think again. The digital age has changed the rules.
So how does digital TV work? Without getting too deep into digital compression and how it affects the superiority of digital television over an analog signal, think of how information is transferred via the World Wide Web. Information is broken down into bits and then converted back into its original format once it arrives at its destination. The same is true of a digital TV signal, and digital compression means that a 19.39-Mbps stream, that is unique to digital television, allows broadcasters to choose the resolution they use to air a program. This is why some stations have multiple channels, i.e. 4.1 and 4.2.
In short, the frequencies allowed for a digital broadcast can be dedicated solely to one station, giving a broadcaster the ability to program a single transmission in high quality, or split the frequency into a lower bit rate and show multiple sub-channels.
Perhaps a misunderstood aspect of digital cable TV is its association with HDTV. Just because we all receive a digital transmission to our homes now does not mean all the programming received will be picture perfect high definition. Digital simply refers to the way the signal is transferred, and the transmission can provide regular programming, as well as HDTV.
Whether or not people understand or care about how digital TV works, the way we watch TV is forever changed. With interactive guides, video on demand and so many other features that can be included with digital cable TV, the enhanced experience that comes with the service has reached a new benchmark in terms of home entertainment. These days it is perfectly acceptable to say you watch TV. In fact, many people might think it strange if you do not.
