The Definition of a Digital TV Tuner

When it comes to digital TV tuners there are several important things you need to know. First of all, there are few kinds of digital TV tuners that are different from each other. The digital TV tuner is generally a device that converts the signal sent from the satellite or the cable to a form that is proper for the TV. The need of digital TV tuner issues from the fact that the satellite and cable industries are not obliged to carry through with government broadcast policies, because these fields are in the private sector.

The TV tuner can be in your TV or it can be a separate device. The tuner in the TV is not always used. This depends on the provider and the type of television you are subscribed to. In case of cable or satellite TV, a tuner (which is normally provided by provider) is needed to convert the scrambled signal, otherwise (broadcast TV) there is no encryption of the signal and the tuner in the TV can’t process it.

When using analog TV to watch digital television, the digital tuner is in a DTV converter box. On the other hand, in digital TVs the digital tuner is in the TV itself (for broadcast TV). Take a notice that there is a difference between digital TV and a common monitor.

The digital TV tuner, when using cable or satellite provider, is a set-top box, unless the subscriber uses a CableCard. In that case, the tuner is the CableCard.

There are digital TV tuners for PC’s and notebooks. They are two types – internal and external. The internal is actually a universal PCI or AGP plate used in both PC’s and laptops. The external ones are boxes connected to the computer by USB, Firewire or equivalent ports.

When it comes to computers, the tuner is called a TV tuner card. This device enables you to receive signals that are designed for TVs on your computer. Therefore, in case you have a TV tuner card you will be able to watch every TV channel on your computer in the same way you watch it on the TV. The TV tuner card has one more option that is useful. It can be used as a video capture card, which is designed to record a TV program on the hard disc of your personal computer. In case you own a more recently manufactured computer, then your video card might function as a TV tuner as well. This is an innovation that has been brought to the market in the recent years.

All that information can make it is easy to understand the importance and the function of the digital TV tuner.
