What is IP TV
IPTV (Internet Protocol
Television) is a system where a digital television
service is delivered using Internet Protocol over a
network infrastructure, which may include delivery
by a broadband connection.
A general definition of IPTV
is television content that, instead of being
delivered through traditional broadcast and cable
formats, is received by the viewer through the
technologies used for computer networks. For
residential users, IPTV is often provided in
conjunction with Video on Demand and may be bundled
with Internet services such as Web access and VoIP.
The commercial bundling of IPTV, VoIP and Internet
access is referred to as "Triple Play" service (when
these three are offered with mobility, the service
is referred to as "Quadruple Play"). IPTV is
typically supplied by a service provider using a
closed network infrastructure. This closed network
approach is in competition with the delivery of TV
content over the public Internet, called Internet
Television. In businesses, IPTV may be used to
deliver television content over corporate LANs.
What Are The Advantages of IP
Advantages of IPTV include
two-way capability lacked by traditional TV
distribution technologies, as well as point-to-point
distribution allowing each viewer to view individual
broadcasts. This enables stream control (pause,
wind/rewind etc.) and a free selection of
programming much like its narrowband cousin, the
IPTV covers both live TV
(multicasting) as well as stored video (Video on
Demand VOD). The playback of IPTV requires either a
personal computer or a "set-top box" connected to a
TV. Video content is typically MPEG2TS delivered via
IP Multicast, a method in which information can be
sent to multiple computers at the same time, with
the newly released H.264 format thought to replace
the older MPEG-2.
