IPTV works by delivering television programming over the internet using internet protocol (IP) instead of traditional cable or satellite signals. The television programming is compressed and converted into IP packets, which are then sent over a network to the viewer’s device. The viewer’s device, such as a smart TV or set-top box, receives the IP packets and converts them back into the original television programming.
The IPTV service provider typically uses a head-end system, which is a central location where television programming is received, processed, and then distributed to viewers. The head-end system encodes the television programming into IP packets, which are then sent over the internet to the viewer’s device.
Viewers can access live or on-demand programming using their internet connection. Live programming is streamed in real-time, while on-demand programming can be accessed whenever the viewer wants to watch it. IPTV service providers usually have a library of content that subscribers can access.
In addition to traditional television programming, IPTV also enables the delivery of interactive services such as video on demand (VOD), time-shifted TV, and digital video recording (DVR). This allows viewers to pause, rewind and record live TV, as well as access a vast library of movies and TV shows.
Overall, IPTV works by combining internet and television technology to offer a more flexible and personalized viewing experience for users.
