How does IPTV Work?

IPTV uses a two-way digital broadcast signal (sent through a switched telephone or cable network by way of a broadband conection and a set-top box programmed with software (much like a cable or DSS box) that can handle viewer requests to access to many available media sources.
The Set Top Box
The viewer's TV connects to a Set Top Box (STB) that decodes the IP video and converts it into standard television signals. The STB is the gateway to an IP video switching system. The Switched Video Service (SVS) system allows viewers to access broadcast network channels, subscription services, and movies on demand. The consumer can access different media by using the television remote to send control commands to the SVS. The unit processes the request and displays the requested media type. Though there are many possible media sources, only one video channel is utilized in the process.
IPTV is an emerging technology and will evolve into a completely interactive experience in the future!
