ABSTRACT
We live in the age of the digital packet. Documents, images, music, phone
calls - all get chopped up, propelled through networks, and reassembled at
the other end according to Internet protocol. So why not TV?
Today, IPTV (Internet Protocol Television) is creating headlines all over the
world. This mass publicity is the result of numerous instances and stories
depicting its humble deployments and its future. IPTV is a very useful
system, through which you can receive both TV and video signals along
with other multimedia services by means of your Internet connection. In a
nutshell, it is nothing but a broadband connection and a system to deliver
various programs of television using the Internet protocol (i.e., language)
over computer networks.
It is important to remember that IPTV is not like any ordinary television
program broadcast through the Internet, but rather it is unique in itself. Its
contour is represented by a closed, proprietary TV system which is similar to
the cable services present today. But, in contrast, the delivery of IPTV is
made via IP-based secure channels, which result in a sharp increase in
content distribution control.
Brief History-What led to IPTV?
The first digital revolution began a decade ago with the mass adoption of
internet and the World Wide Web and the launch of digital television
services via cable, satellite and terrestrial networks. These two remarkable
developments in communication coincided, but failed to converge.
Several attempts were made to marry broadcast television with the internet,
but even as analog television began to give way to digital, the medium and
the TV screen remained resolutely detached from the PC and the global
network of the internet.
Historically, television was either transmitted from a tower, or distributed
over a cable system, or beamed directly from a satellite. Today, as we enter
the second digital revolution, as a result of high bandwidth and high speed
internet access, it has become possible to transmit television and other audio
and video services over broadband data networks over a single connection.
That could be over a cable television system but it could equally be over a
telephone line.
INTRODUCTION
What is an IPTV?
IPTV is not an application per se; it is a host of applications centered on IP,
user choice, and rich content.
DEFINITION:
IPTV, essentially, has two components:
Part 1: Internet Protocol (IP): specifies the format of packets and the
addressing scheme for a network. Most networks combine IP with a higherlevel
protocol. Depending on the vendor solution, user datagram protocol
(UDP) is the most typical higher-level protocol. The protocol establishes a
virtual connection between a destination and a source. IP allows you to
address a package of information and drop it in the system, but there’s no
direct link between you and the recipient.
Part 2: Television (TV): specifies the medium of communication that
operates through the transmission of pictures and sounds. We all know TV,
but here we are referring to the services that are offered for the TV, like
linear and on-demand programming.
Why IPTV?
Consumers always want more and high quality. Now days most of TV are
analog with one way data transmission and limited channel. IPTV provides
all digital, two ways connected, unlimited channels, integrated (DRV,
HDTV, PIPs, VoD) and personalized TV. IPTV enhances the TV offer and
delivers in a new way to provide better experience to watch TV in a Simple,
Personalized and in an advanced way.
How does IPTV Work?
Before we get into the internal details of the way the IPTV network is
configured to provide transmission of television signals, we see what are the
various steps followed to convert the audio and video feed signals into a
suitable form to be transmitted in the form of IP (Internet Protocol) packets,
which forms the basis of the whole concept of IPTV and how they are
received on the other side as television signals.
