Abstract
The goal of this course was to give an insight in what is done in the industry in the area of computer
communication and distributed systems. This was done through some seminaries and a small project. In the
project a relevant topic was to be chosen and studied. I choose to investigate how IPTV works and what its pros
and cons are against today’s cable, terrestrial and satellite television.
Introduction
1.1 Background
This project is a part of the course EDA390 Computer Communication and Distributed Systems which in turn is
a part of the Communications System concentration at the department of Computer Science and Engineering at
Chalmers University of Technology.
1.2 Aim
The aim for this project/report is to get a better understanding on IPTV works and what its pros and cons are
against the more common distribution mediums cable, terrestrial and satellite.
1.3 Project assignment specification description
The project was to do a concentration in relevant topic in the area of Computer Communication and Distributed
Systems. I chose IPTV as my topic and to investigate in how it works and why we might choose it instead of
cable, terrestrial or satellite. The focus was on which pros and cons there is with IPTV.
IPTV
2.1 What is IPTV?
With IPTV you usually mean distribution of television or video content over a controlled IP network, where the
end consumer receives the information through a set-top box which is connected to its normal broadband
connection. Just because its name is IPTV (Internet Protocol Television) it dose not mean that information is
sent over the internet, only that IP protocol is used. So you should not consider streaming video over the internet
as IPTV.
2.2 What features does IPTV offer?
The biggest difference with today’s distribution of television is that you choose which information you want to
have everything is not broadcasted as with terrestrial, cable and satellite. Another big difference is that you will
be able to have a high capacity two way communication and have the ability to interact with the service
provider, for example you request a movie from your TV-guide and the program is delivered to you. Other
things that could be provided with IPTV is interactive applications (e.g. video blog) or transactional applications
(e.g. TV shopping). Because of the point-to-point connection IPTV offers, every user will be able to view their
own individual broadcasts. You will be able to have VoD(Video on Demand) which is your on personal video
store where you can decide when you want to see the movie. EPG(Electronic Program Guide) and
PVR(Personal Video Recorder), where the EPG will be fully interactive with your own personal needs. You will
also be able to use features like pause, fast forward and rewind when you are watching a movie on your TV. It
will be possible to have personalized advertising. You will be able to decide yourself, which kind of advertising
you would like to see.
