IPTV successfully combines two established technology standards:
IP data with IGMP protocol
for multicast streaming MPEG
TV compression
IPTV systems benefit from the use of other IT standards such as:
POE: Power over Ethernet -
used to provide power across the network to IPTV receivers
SAP: Session Announcement Protocol
-
used to announce available IPTV channel streams to network
display devices
SNMP: Simple Network Management
Protocol -
used to support monitoring of network-attached devices, and
can also be used to provide limited control of parameters
within those devices.
IPTV is the convergence of television
distribution with IT data infrastructure.
IPTV systems take digital terrestrial television and satellite channels received
at broadcast quality, and IP wrap them to provide live IPTV
channel streams on a local area network (LAN) or wide area
network (WAN).
This approach can be extended to include encoded local sources,
such as DVD or a camera, video on demand (VOD) channels from
client owned servers, and Digital Signage; the last of these
offering combinations of graphics, live TV and file-based
content to deliver compelling screen displays.
IPTV successfully combines two established technology standards: IP Internet Protocol data transmission - the most commonly
used data transport system; and Digital Television distribution using MPEG compression
standards.
Using standard IT protocols to deliver video services allows
the advantages and continuous improvements in IT technology
to be applied to TV and video distribution.
