IPTV services are mainly classified into 3 groups, explore to know which are those:

1. Live stream or television: with or without interactivity that either broadcast source through IP camera or encoder.

IPTV can also be defined as the reliable and secure delivery of live streams, entertainment video, and related services across an IP (internet protocol) data network. These services may include encoded streams, Video On Demand (VOD), interactive TV, and broadcast TV.

These services are delivered successfully across a network using the IP protocol to transport the control signals, audio, video, and securely delivering them to smart devices, TVs, media players, set-top boxes, laptops, thin clients, Macs, etc. In contrast to video on the public internet along with IPTV deployments, network security and performance are managed efficiently to ensure a professional experience, resulting in a compelling business environment for content providers, advertisers, and customers alike.

How Does IPTV Actually Work?

IPTV can either be viewed on a PC monitor or TV set using a Set-top box (STB) device or any other device having an internet connection. It simply demands a broadband connection to access IPTV services. The STB provides great help as it enables accessing the desired channels as per subscription services on particular users’ demand. It also obtains interactive multimedia services over a secured connection with desired QoS.

IPTV services are deployed by several service providers such as satellite TV companies, telephone companies, cable TV carriers, and many more. In addition to video, IPTV technology also offers VOIP (voice over IP) as well as web access for the data. These 3 services offered simultaneously by IPTV technology are popularly known as triple play, while the fourth feature includes mobile telephony, which gets added, which is known as quadruple play.

Now let’s have a quick look at the working of IPTV technology. The above figure depicts IPTV Architecture, which mainly includes a super head-end, local office, subscriber premises, and regional head end.

At the super head end, all the content from national channels is stored and downloaded. These contents are later processed and prepared for transmission over high-speed internet links such as FTTH (fiber to the home) or DSL.

The contents from the super head end are distributed using MPEG-2 MPTS (Multi-Program Transport Stream) to video nodes that are available at the regional ends. The multicast IP address is used for each of the channels for IPTV distribution.

Later it is distributed to a regional head-end office where local content is combined with advertisements and stored in on-demand servers. This content is later distributed to local end offices using high speed wired internet links as well as using an antenna to provide wireless connection.

At the local office, data and telephone services are combined with IP video services using DSLAM (Digital Subscriber Line Access Multiplexers).

The combined information is distributed to the subscriber premises using DSL (Digital Subscriber Loop) links or using fiber-optic links. Depending upon applications of use, this input connection is converted into appropriate forms. For example, to obtain voice, the input is split using DSL splitter and fed to the telephone set; to obtain IP data, a DSL modem is used to convert the input to IP data form to be fed on desktop PC or laptop; to obtain video and audio STB is used and fed to the TV set.

Future of IPTV: It Has Long Way to Go!
