IPTV and VoD
IPTV (Internet Protocol Television) is a method of securely
distributing video content to televisions over a managed two-way
network IP infrastructure that enables a more customized and
interactive user experience.
IPTV can enable interactive content, such as interactive
advertisements and real-time network based PVR functionality, on
a regular TV set. IPTV can allow people who are separated
geographically to watch a movie together, while instant
messaging and exchanging files
simultaneously. IPTV can enable providing a mosaic of multiple
video sessions on screen at the same time. It can support a
richer VOD storefront and features like photo sharing.
IPTV & OTT Video
IPTV uses a two-way path using a downstream multicast or unicast
video signal sent through the providerís backbone network over
IP and from IP-based video servers, allowing viewers to select
content on demand, time-shift, and take advantage of other trick
and interactive TV options. At the access interface, IPTV is a
unicast service; only one copy of a program is sent at a time on
the access pipe connecting the user to the network. When a
viewer changes the channel or selects a program, a new stream of
content is transmitted directly to the viewerís set-top box.
There may be a large number of streams of video being sent into
the IP core network, but only one is switched into the userís
DOCSIS cable network modulates one downstream channel to
provide an effective data rate of 37Mbps using QAM 256
modulation profile for North American cable plants. Under
European cable plants it can provide 52Mbps of effective
bandwidth utilizing one available channel. The
number of available channels available in a cable network is
more than 100.
To provide IPTV or VOD over IP multiple IRIS CMTS are stacked
thus effectively increasing the total bandwidth required to
provide such services.
IP to QAM Gateway
Our IP to QAM gateway solution is ideal solution to deliver
OTT Video streams on an existing Cable infrastructure. This
technology allows delivery of OTT Video directly to clear QAM
enabled televisions that are widely prevalent without the
requirement of expensive IP set top box.
With our IP to QAM gateway your property can deliver OTT
Video at fractional cost of a full IPTV Video system.
IP enabled TV will bring new ways to deliver
Cable networks are scalable and can now
deliver twelve video streams using the same channel that it
could earlier deliver one video stream.
