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 provider’s 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 viewer’s 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 user’s access network.

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 content.

OTT Video
	Over-The-Top (OTT) Video is also referred to as "Internet Video", "Web Video" and "IPTV". OTT video is simply video that is delivered over the Internet to a PC or to a device that is connected to the Internet, like a Internet ready TV, Set Top Box or a gaming console.

Cable networks are scalable and can now deliver twelve video streams using the same channel that it could earlier deliver one video stream.
