Satellite Tv Trends - Watch Digital Tv On Your Pc

The reign of the conventional television receiver is coming to an end
The technological world that you live in is changing at an alarming rate. Who would have thought that the presence of the humble TV set in your home would be under threat by home computers that are still regarded by many as nothing more than toys. It seems that suddenly we are surrounded by digital television signals from sattelite, cable and terrestrial broadcasts not to mention the revolution in digital video in DVD format. The mere fact that this material is delivered in digital form makes a computer the logical choice for handling it.
Your television used to be the best and in some instances the only way to get up to date information about current affairs and news. This is no longer the case now that we have computers in the home connected to a planet-sized library of information called the Internet. You can get up to date information about literally any topic instantly by browsing the Internet whenever you feel the need.
Do you need that TV set anymore?
The home computer revolution has crept up on us almost without notice and it might come as a big surprise to you to find that your computer is now capable of doing everything that your TV set can do and a lot more. It wasn't so long ago that to have the kind of processing power needed to decode and play full motion digital video from sources such as sattelite, cable and terrestrial broadcasts, not to mention DVD, would have been unthinkable. When you sit down and think about it you might want to consider buying a PC the next time you go shopping for a TV set.
The secret to using your TV to watch digital video
When it first became possible to watch digital video, or analogue video for that matter, on your PC you were required to install a video capture card inside your PC. You then had to find a way to get your chosen source of signal converted into a form acceptable to the add-in card. Typically you had to provide an analogue signal for the capture card. This provided an acceptable solution for desktop PC's but it wasn't very good for notebook PC's.
Here come cheap powerful notebooks with USB 2 interfaces
You can now get good notebook PCs for prices
comparable with television sets. They are equipped as standard with USB 2 interfaces which are fast enough to cope with a digital TV data stream from an external receiver. This means that modern desktop and notebook PCs are capable of transforming themselves into digital TV sets provided that you can find a source of digital TV data.
USB 2 and satellite television
The USB 2 interface is one of the most significant additions to the PC in recent times. It is fast enough and versatile enough to handle a variety of applications including digital video. Manufacturers have seized this opportunity to bring you all manner of gadgets that become part of your computer simply by plugging them in.
There are USB digital TV units available for terrestrial, cable and satellite TV so you should have plenty of choice. All these devices conform to the DVB (Digital Video Broadcasting) standards in 3 basic versions. DVB-T for terrestrial TV, DVB-C for cable TV and DVB-S for satellite TV.
Disadvantages of using a USB digital TV adapter
Adding a USB digital TV adapter to your desktop or notebook computer can easily and cheaply turn your computer into a very nice high specification television with all the trimmings of digital storage and time shift viewing etc. If you want to receive encrypted pay for view channels then you will have to use a decoder box that is supplied specifically for the service you are subscribing to. You can of course feed the output of the external decoder box into your PC using a USB 2 analogue video adapter.
Digital PC TV is the future
As computers become more and more like TV's the need for a standalone TV set will diminish and ultimately vanish. I don't know when this will happen but it might be sooner than you think.
