To turn you computer into a television you will required to spend some money on hardware. You will need a PC TV tuner card, they can either come with USB or PCI interfaces. You can use the PCI version with a desktop PC, the USB versions can be used with a laptop or desktop (as long as you have a free USB port). The adaptor is used to decode the TV signal and display it on you desktop or notebook.
Both type of HDTV adaptors come with many different features, not only do they allow you to watch television broadcasts on your PC they have features such as, radio stations, video and audio capture and live pause. Most types come with software which will have to be installed.
Some TV tuner adaptors have inbuilt aerials and/or a connector for an external aerial that comes supplied. For the best result you might want to check if the adaptor has the right type of connectors to connect to your satellite or set-top box if that?s your chosen method of viewing. They normally come with software to tune the adaptor into the TV channels and allow you to perform other functions like recording and pausing TV channels.
TV tuner adaptors do not cost much (you can pick them up for less than $60). They are readily available online from most computer retailers. Makers of HDTV tuners include Creative, Leadtek, ATI and Pinnacle. When choosing the adaptor be sure to choose one which is HD capable if you require to watch high definition broadcasts.

OLED Televisions: The Next Generation In TV Technology
There has been an awful lot of noise within the TV manufacturing industry about the rise of OLED televisions over the last few years. Recently, this entered the public the domain as companies start to launch the technology. But is it really worth all the attention, how does it work, and what will it cost?
Firstly it is important to discuss just what OLED means. Standing for Organic Light Emitting Diode, these diodes give off their light in a different way than what has gone before. Its predecessors came in the form of LCD (liquid crystal display) and LED (Light Emitting Diode) television screens. The screen is made up of several conducting layers which emit light through an organic process; thus a backlighting function is not required.
This allows far richer and deeper colors to be produced. Indicative of this is the reproduction of “true” black; essentially the same black seen in nature. This is fundamental to the industry, as the quality of black produced defines the quality of the complete imagery.
This is just the start of where the next generation in TV comes in however. Because the screen itself produces the light, there is no need for separate technology to be built into the unit. Resultantly, a thinner screen is produced, whilst they can be manipulated into a host of different shapes.
The screens are also virtually indestructible, so could easily be turned to other uses such as; billboards that curve round corners or clam shell cell phones that are entirely made up of a touch-screen. This is for the future though; presently the major benefit is in TV screens that are up three millimetres in thickness!
However what the screen “lacks” in depth, it also certainly LACKS in size. Presently, the biggest screen made, (and shown to the public), is a rather small fifteen inches. However, despite this, resolution and contrast are amazing.
Other than screen size, the obvious downside when looking for OLED televisions is the price. You can expect to pay a minimum of two thousand five hundred dollars for a screen size of just eleven inches. For that amount you can get a good quality forty inch (and upwards) LCD screen, so this puts it beyond the reach of most.
They also have a relatively short life span. Conversely, the main competitor in the market, the LED television is very generous in its longevity. Availability at the moment is also not very high; though this in itself is indicative of the very latest technological releases.
It is still a relatively young technology though; with a lot of advancements yet to be made. The price will of course fall as demand picks up, the technology really becomes commercially viable and life span is improved.
In summary, the advantages of OLED televisions now and for the future will outweigh any disadvantages. They are the greener option; subsequently consuming fewer resources and the picture clarity is unparalleled.
