How TV Tuners Have Evolved

What exactly is a TV tuner?

 It has evolved from being a core function of a standard television set to something as small and compact as a USB device that can be plugged in and used with any desktop and laptop. If you have never quite understood the concept of using a TV tuner to capture TV broadcasts on a computer, then this article will provide you with the basic rundown.

 TV Tuners were originally designed to change channels in the older TV sets – they operate by receiving signals from a communications network which broadcasts over a particular area and translates it into a signal that the TV can understand. Sound image and video would then be displayed correctly on the screen, since the television had a working ‘converter’ that was acting as a median for a variety of different signals, allowing for streams of different channels.

TV Tuner cards operate just exactly the way that a standard TV tuner would work, except that they have been specially designed for laptops and home computers. These devices can receive broadcasts just the same way that a television would. They can be as small and portable as a USB device – just think of a mobile broadband system that runs off a USB. Laptop TV tuners work in exactly the same way, except they feed off broadcasted TV signals. Since many countries offer to broadcast a certain number of TV channels for free, you can watch it all on a laptop whilst on the move.

This is one of the advantages of using a TV tuner. With the evolution of the TV tuner card to something small and portable, it is now possible to watch TV from anywhere, as long as the broadcasting strength is strong enough for the card to receive. This means that watching TV is no longer limited to just home or a place where the TV collects dust every day, but right alongside you with the aid of a TV tuner card.

If watching television on a computer becomes a routine, there are also express cards which act as a hardware device which also detect television signals and display them on the computer. They run through a standard PCI/PCIe slot, which can be found on any home computer. This saves time configuring other types of TV tuner devices.

The TV tuners have changed from being used simply in televisions to being able to adapt to computers and desktops. As technology advances, so do the possibilities of TV tuners. As popularity for the product increases, there will be many new designs of portable TV tuners possibly even for devices aside from computers, taking their usage to a whole new level.
