Media-over-the-Internet Set-top Box (Maybe known as IPTV STBs) - IPTV uses a two-way digital broadcast signal that's sent through a network by way of a broadband connection and a set-top box (or equivalent). These set-top boxes are programmed with software that can handle viewer requests for accessing various media sources. The viewer's TV connects to a device that decodes the IP video and converts it into computer data, or an analog signal, that the television can understand. The set-top box (or equivalent device) is the gateway to an IP video switching system. This system allows viewers to access broadcast network channels, subscription services, and movies on demand and much more.
