In order to compete against cable's triple play, telcommunication companies started offering TV programming through their high speed Internet connection. This makes it possible for telcos to offer the quadruple play, which is a combination of wireless phone, Internet, land-line phone and TV programming.
IPTV can be viewed in several ways. A computer may be used to reassemble protocol packets and convert them into a television signal that can be recognized by standard television set. Another option is the set top box, commonly used by cable companies. The set top box would be used in place of a computer and would do the same job a computer does.
But because IPTV is based on the Internet Protocol, it is sensitive to packet loss and delays if the IPTV connection is not fast enough and it also does not support HDTV at the moment.
