Internet protocol television, or IPTV, uses a two-way digital broadcast signal that is sent through a switched telephone or cable network by way of a broadband connection, along with a set top box programmed with software that can handle viewer requests to access media sources. A television is connected to the set top box that handles the task of decoding the IP video and converts it into standard television signals. The Switched Video Service (SVS) system allows viewers to access broadcast network channels, subscription services, and movies on demand. *
