What is IPTV
IPTV technology allows to broadcast television into IP networks with HD video and multi-channel audio. To achieve that, it requires: an IP network with multicast broadcasting support, a head-end that receives external digital TV signals and manages all the IPTV system, and set-top boxes for subscribers' TVs.
The IP protocol allows to organize two-way connections between head-end and set-top boxes. Thank to all that, users can enjoy the interactive TV and other media features not available to classical television subscribers.
