instead of being delivered through traditional terrestrial, satellite signal, and cable television formats.
IPTV, Internet Protocol television is a system through which television services are delivered using the Internet Protocol suite.
IPTV services may be classified into three main groups:
- Live television, with or without interactivity related to the current TV show;
- Time shifted television: 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 a catalog of videos, not related to TV programming.
