TV tuners
Broadcast signal decoders
A TV tuner is a device that receives television broadcast signals and converts them into audio and video.
Tuners are built into televisions but also exist as standalone units or computer cards: I installed a TV tuner card so I could watch live broadcasts on my laptop.
As streaming has displaced broadcast television, dedicated TV tuners have become less common.
