Is this the end of the TV receiver, as we know it?
Ever since the 1930s we have purchased and used standalone TV sets for entertainment and up to date information but now things are changing. We live in a world that is very different from what it was only a few years ago, a world where digital TV, Satellite TV, computers and the Internet are all around us. Today the computer is as common in the home as the TV set is. I know of many households that actually have more computers than they have TV sets. We use computers routinely for gathering information and research. Only a few short years ago this was the role of television news and current affairs channels. The TV channels haven't gone away but we rely on them a lot less than we used to. It's often so much easier to reach for the Internet browser on your PC especially when you need the information right now. So why do we need a standalone TV set?
That's a very good question. Until recently the computer that you might typically use in your home hasn't had the power or capacity to perform the same functions as your TV set but this is no longer the case. Even the most humble of modern notebook PC is now capable of receiving and playing digital TV from sources such as terrestrial, cable or satellite digital TV. You can even watch analogue TV transmissions until they are phased out. How to watch satellite digital TV on your PC?
Not very long ago in the early days of PC TV it was necessary to install a TV capture card inside your computer in order to watch television broadcasts without using a standalone television. This was not a difficult task but it wasn't simple or elegant either. It also made it unsuitable for use with notebook PC's which limited the appeal somewhat. Notebooks were also less common and more expensive a few years ago so there was no incentive to develop such systems. Along came cheap powerful notebook PC's and USB 2
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 satellite TV
It turns out that there are many products available that are designed to receive and decode digital TV signals and deliver them to your PC through its USB 2 interface. Installation couldn't be simpler, just install some software and plug the device into your PC. 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 digital television adapter to your PC to watch free-to-air broadcasts is a great idea but if you want to subscribe to any encrypted pay-for-view channels such as Sky in the UK you may be unlucky. At the time of writing the only way to watch these channels is through a set top box designed for the service. 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. |
