A TV tuner is a device that allows television stations signal to be received by a computer. They can also act as video capture cards which can record TV programs into
hard disk memory.
TV tuner cards come in four different types. They are the analog tuners, digital tuners, hybrid tuners and the combo tuners. The analog tuners are cheaper and ideal for live viewing and do not suit for video recording. It uses more system memory if used for recording.
The digital tuner gives the viewers the digital audio video quality and record the TV program in the mpeg format. The hybrid tuner can also be used as the digital tuner and switching in between the TV and the system mode is quiet simple.
The combo tuner has two different tuners where one can record and the other can play live TV. Its flexibility to be used as both the digital and analog tuners and its cost is making it more popular now a days.
Another interesting fact is that the TV tuner can also act as an FM radio since both their frequencies are too close to each other.
