The world today is kind of a hectic place. All the people, and we are no exception, are always in some kind of a hurry. They are striving to complete their goals and this somehow takes so much of their time that there is simply no entertainment part of their lives. Nowadays, it is quite common to have a pretty long workday, which will be filled with so many challenges and troubles that it is going to be normal that you would want some kind of relaxation after it. And, to be honest, who doesn't want to just sit or even lie in their living room, watch TV on their big-screened wonder of technology and do absolutely nothing? If someone had told you 20 years ago that the flat screens are going to be something common, you surely wouldn't believe them. However, nowadays they really are pretty common and popular. Also, there is the 3D TV's which are beginning to gain popularity. Still, their prices are quite high so until it's affordable for our budget we need to enjoy the €simple' things that we have, and indeed €" perfect sound and crystal clear picture. Of course, these things are not granted and in order to have them you will need a device, which is called DVB tuner.

DVB stands for Digital Video Broadcasting and is actually used for the broadcasts of television. In order for this broadcast to be transmitted, there are three ways €" it can be broadcasted by satellite (S), cable (C) and terrestrially (T). There are still some doubts about the matter of which one of these methods is the best one for the signal broadcasting, but for now we are at the point where it is either the satellite or the cable one. So, here is some information about the DVB-C tuner.

This system for cable broadcasting uses QAM modulation. This way it transmits digital video or audio streaming from MPEG-2 to MPEG-4. Of course, this sounds really complicated when in fact it's quite simple. In fact, the three channels (audio, video and data) are converted into the format called MPEG. When this happens the MPEG stream is being transported to the box by another MPEG stream. The top box of the set (the DVB-C tuner) receives that signal and then modulates it. Its bitrates may vary from six to forty-six Mbts per second.

You can purchase your DVB-C tuner as a separate device. As most of the new products it comes in different colors and sizes. The size of the DVB-C tuner device will usually be quite compact and small, so you will be able to use it in most of the places where you will go. Also, there are models of TV's which have a tuner embedded in them. Many people prefer to buy such kind of TV; however, its price range is quite high so it is not made for mass use.

Once you have bought your DVB-C tuner and use it, you will be surely asking yourself how you have lived without it.
