This refers to the process of acquiring programs designed to enable a computer or compatible device to receive and process digital terrestrial television (DVB-T/T2), digital cable television (DVB-C), frequency modulation (FM) radio, and digital audio broadcasting (DAB) signals. Functionality involves tuning to specific frequencies, demodulating the received signal, and decoding the audio and video data for playback. An example would be installing a program on a PC that allows the user to watch over-the-air television channels through a connected USB dongle.
The capability to access a wide array of broadcast media through a single device offers considerable convenience and cost savings. Historically, separate devices were required for television, cable, and radio reception. This integration reduces hardware clutter and provides a centralized platform for media consumption. Moreover, accessing digital broadcasts often provides higher quality audio and video compared to analog counterparts, and it can include additional features like electronic program guides (EPG).
