Set-Top Box (STB)

The term set-top box describes a device that connects to a television and some external source of signal, and converts the signal into picture displayed on the screen and sound. The signal source might be a satellite dish, a cable, a telephone line, a DSL connection, or even an ordinary VHF or UHF antenna.

In IPTV networks, the set-top box is a small computer providing two-way communications on an IP network and decoding the streaming video.
