How to Connect a Digital Set Top Box to a TV Tuner Card
A PCI TV tuner card in combination with a digital set-top box allows you to transmit live TV broadcast signals on a personal computer.
Unlike the USB TV digital set Box which connects to the computer via USB ports, a PCI TV tuner card plugs onto a motherboard PCI slot. PCI is short for peripheral component interconnect. A PCI device is hardware that adds functionality to a desktop computer when plugged onto a PCI slot.
When TV tuner card is installed, connectivity with the decoder, sound card and\or TV antenna to the TV card is done at the rear of the computer.
Despite their dwindling sales, desktop computers are still available and remain a common form-factor worldwide. In developing countries, in particular, use of desktops will probably remain popular for a long time, and so will the habits that go along with using them. Out of many, the use of computers as television sets is still popular.
A computer can be turned into a TV set via USB TV set Box or the PCI TV tuner card.
The TV set-top box can be used externally both with the desktop or laptop computer - via USB, while the PCI TV tuner card has to be plugged onto a PCI slot inside the system unit.
Common PCI TC capture cards support both analog and digital signal transmissions. Much as analog TV is meant to be a thing of the past, quite a number of countries continue to transmit analog signals.
Many providers, however, continue to transition from analog to digital transmission and users are gradually tagging along.

In order to install and transmit digital signals via the desktop computer, you should have the following accessories at hand, in addition to TV aerial.
- PCI TV tuner card with RCA video input jack.
- An RCA (yellow) video cable.
