There are two types of TV tuner cards available in the market. One is internal and the other is an external TV tuner card. The internal card is assembled with the CPU of the computer, where as in case of external card, there is no use of CPU, only computer monitor or such output device is used along with the TV tuner card. But it is always recommended to use the external TV tuner card as internal card may affect CPU performance.
There are many more TV tuner brands available in the market. If you are looking for lower range below INR 1000, then you can think about Frontech, Intex etc. But you will not get quality and clear resolution. If you can afford INR 1300 to 1400, you will get the iBall TV tuner card, which is the best in this price range.
