3. IPTV
IPTV stands for Internet Protocol Television (aka
Interactive & Personalized TV, TV over IP)
It streams (downloaded and played almost
simultaneously) a TV program through your
Internet connection instead of receiving as
broadcast signals that enter your home from a
rooftop antenna, satellite dish, or fiber-optic
cable.
A process of sending television signals over IP
data networks.
These IP networks can be a managed e.g.
Digital Subscriber loop or an unmanaged
network e.g. Broadband Internet.
It needs a Network Connection with a download
speed of maybe > 10 Mbps & Upload Speed of
>3 Mbps.

4. IPTV Classification
Video On-Demand (VOD) / Over-The-Top/ Internet Television: A service in which Viewers choose their entertainment program from a wide range,
may pay your money, and watch it there and then.
 SVOD – (subscription video on demand - Subscription based-Monthly Payment-Flexible Commitment) E.g. Netflix, Amazon, Hulu, Sky, EROS Now
 TVOD – (Transaction based-Single Rental/Purchase-Recent Releases/Live Events) E.g. Amazon Instant Video, Sky Cinema HD, Itunes, YouTube
Movie
 AVOD – (ad subsidized platform – “free” services to users – pay to remove adverts) E.g. YouTube, Vimeo, TVF Play, Voot
Time-Shifted IPTV/Digital Video Recorder (DVR): You watch ordinary, scheduled broadcasts at a time that's convenient for you. Providers of IPTV
allow users to watch recorded shows without DVR devices. E.g. In the UK, the BBC (British Broadcasting Corporation) makes its last week's programs
available online using a web-based streaming video player called the BBC iPlayer.
Live IPTV : It involves multicasting live TV programs across the Internet as they're being watched—so it’s a live IPTV.
All three forms of IPTV can work either using your computer and an ordinary web browser or (for much better quality) a set-top box and an
ordinary digital TV.

5. Past-Present
The term IPTV first appeared in 1995 with the founding of Precept Software. Precept developed an internet video product named IP/TV.
It was a Windows and Unix-based application that transmitted single and multi-source audio and video traffic, ranging from low to DVD
quality. Precept was acquired by Cisco Systems in 1998. Cisco retains the IP/TV trademark.
Kingston Communications, a regional telecommunications operator in the UK, launched KIT (Kingston Interactive Television), an IPTV over
DSL broadband interactive TV service in September 1999. Kingston was one of the first companies in the world to introduce IPTV and IP
VoD over ADSL.
Life was Simple: A phone Line to connect your landline & an Antenna for TV. Then Came a 2nd wire to your home for cable TV (better
picture, more choices) : Cable line for TV + Phone lines
Emergence of WWW:
 Cable service provider started providing Data service : TV + Internet Line+ added Phone services (digital phone service)
 Telephone carrier added TV service to their portfolio.
Cut the Cord: Consumer can access OTT services thro Internet which led to cutting the cord for cable services.
Survival / Competing Strategy:
 Cable Companies came up with the idea of TV Everywhere (if you have subscription & authentication, you will access it). Cable companies moving their
content on to web devices.
 Telephone companies are going in other direction providing web content in tv as traditional phone business is in decline thus saving their cord from cutting.
 With online viewership is increasing, Telecom Companies are investing on IPTV in order to widen their product offering & to grow up their customer base
where they at least can retain their current customers.

6. IPTV
Architecture
At super head end, all the programs
from national channels are downloaded
and stored. These contents are
processed and prepared for transmission
over the high speed internet links such as
DSL or FTTH
At regional head end office where local
contents mainly advertisements are
combined and stored in on-demand
servers
At the local office, data and telephone
services are combined with IP video
services using DSLAM.
The combined information is distributed
to the subscriber premises using DSL
links or using fiber optic links. Depending
upon applications of use, this input
connection is converted into appropriate
forms.

7. IPTV Architecture(continued)
Storing Programs: Live programs are streamed as they're produced, but
prerecorded programs and movies need to be stored in such a way that they can
be selected and streamed on demand. Some VOD services limit the number of
programs they make available not because they're short of storage space but
because that's one way to limit the overall bandwidth of their service and its
impact on the Internet.
Preparing programs: Convert the program to digital format then compress it
(MPEG format), add the advertisements & Encrypt it.
Streaming programs: IP Unicasting & IP multicasting
IPTV protocols: HTTP (Hyper Text Transfer Protocol) for Data Transfer, IGMP (IP
Group Membership Protocol) for Live TV and RTSP (Real Time Streaming
Protocol) for Video on Demand services.
Managed Networks: IPTV provider controls the entire network so that they can
guarantee a level of quality and service.

8. Digital TV vs. IPTV
Digital TV has a huge customer base vs. IPTV
QOS is a concern for IPTV amidst network limitations in India & other
parts of the world .
Digital TV is competing through TV Everywhere business model
IPTV Triple Play/Quad Play could play a revenue generator / customer
retention model
IPTV is based on a two way protocol; it gives user greater interactivity
with content and medium. Digital TV is still at exploration stage.
