IPTV

IP + TV

Providing television over IP networks

television is still a major media type
Television is still a major media type
  • What users expect?

- They switch on and select TV channels

The goal of IPTV is to provide this but using

IP network, instead of traditional broadcast over

the air, cable, satellite.

The difference from the ”Internet TV” is that there is no waiting, buffering and QoS is like normal TV.

how to make iptv system
How to make IPTV system?
  • One has to define the requirements
  • On has to develop architecture for it satisfying

the requirements

This has been done in by Open IPTV forum,

organisation grouping major industry interested in this area. In March 2008 they released specifications for IPTV standard

We use it as an example of multimedia system

design

IPTV features
  • Nowadays the features can not be only TV,

IP networking and digital media offer much more

possibilities, e.g. VOD – Video on Demand

Basic architecture
  • From the features the basic architecture follows

This is singel architecture supporting multiple services, there is managed

part and open Internet part. There are different providers in the system.

what this diagram means
What this diagram means?

Functional entity performs certain function

required for the system operation

This function should be available at specific

reference point. Reference points are marked

By their location and function e.g.

UNI – User to Network Interface

UNIT- UN Transport Interface

These elements have to be precisely defined

for the system

conclusion
Conclusion
  • The Open IPTV architecture is very comprehensive
  • The standard is presented in a way typical for

modern telecommunication systems: functional

entities and reference points are defined and described in detail. Next the system operation

is explained using diagrams.

  • Open IPTV uses the concept of ”managed” and open Internet. The managed part provides guarantees for

content delivery and defines sets of protocols for achieving this.
