Iptv = internet protocol tv
Instead of paying a cable or satellite bill, you pay for the ability to stream TV channels and content to the device of your choice.
IPTV services may be classified into three main groups:
Live television and live media, with or without related interactivity;
Time-shifted media: e.g. catch-up TV(replays a TV show that was broadcast hours or days ago), start-over TV (replays the current TV show from its beginning);
Video on demand (VOD): browse and view items in a stored media catalogue.
