What Is IPTV

Internet Protocol television is the delivery of television content over Internet Protocol networks. This is in contrast to delivery through traditional terrestrial, satellite, and cable television formats. Unlike downloaded media, IPTV offers the ability to stream the source media continuously.

How does IPTV work?

IPTV is much similar like browsing the internet than traditional channel surfing. It merely uses IP (Internet Protocol), a transport protocol which is a delivery mechanism to deliver the videos to the viewer. When the viewer clicks on any TV program or requests the video, video from different sources (servers) is divided into data packets and sent over the internet. Video servers transmit programs through fiber-optic cable to existing household via internet connection and requests are sent out and shows are sent back.
