Aside from watching TV, TV tuner adapters are computer components that make it possible to receive television signals by way of a desktop or laptop computer. Sometimes referred to as a RV tuner card, the device may be in the form of a PC card or a USB device, making it possible to use an adapter with older systems, assuming they have the resources to process the inbound signal. Many of the tuners today are configured to receive both analog and digital signals, with some even equipped to capture the video stream and save it to the hard disk.
The most basic of all TV tuner adapter options is the analog TV tuner. This device is capable of receiving and processing analog signals, delivering a clear and crisp image on the computer screen. As more countries move away from analog television signals and go with digital signaling, this particular version of the TV tuner adapter has fallen out of favor with many users.
