INTRODUCTION
IPTV-The reinvention of televsion

WHAT IS IPTV?
It is a technology that delivers video or TV broadcasts over the Internet.
Internet TV, in simple terms, is video and audio delivered over an Internet connection. It's also known as Internet protocol television, or IPTV.
You can watch Internet TV on a computer screen, a television screen (through a set-top box) or a mobile device like a cell phone.


ADVANTAGES
True interactive television.
See anything you want to see, any time, any where, on any device .
Reduced infrastructure costs.
IPTV works on your existing internet connection.
Infinite number of channels .


Mobile IPTV
Video or TV broadcasts over the Internet on Mobile Devices.
Transmit and receive Multimedia traffic-TV, video, audio, through IP based Wireless Networks.
Using IP based services including IPTV anywhere on earth.


Architecture for Mobile IPTV

 Different Approaches for Mobile IPTV
Mobile TV plus IP Approach.
IPTV plus Mobile Approach.
Cellular approach.
Internet Approach.


Mobile TV plus IP approach
Traditional Digital broadcast networks to deliver IP based broadband data services.
Combines broadcasting service and Internet.
Audio/Video Services to be delivered to and through the mobile device via IP networking.
May incur the loss of individuality of IP.

IPTV plus Mobile Approach
IPTV beyond fixed terminals such as Set top Boxes.

Provides mobility and wireless characteristics to IPTV.

Mobility Services based on IMS(IP Multimedia Subsystems)

Cellular Approach
IP based Mobile broadcasting networks.

Applicable to mobile terminals.

It is BEARER AGNOSTIC - any broadcasting distribution network can be adopted as its distribution networks.

Internet Approach
Already countless video services.

Quality of service not guaranteed.

Highly diversified and dynamically independent.

Mobile devices “ Internet “ various wireless networks.

TECHNICAL OBSTACLES


Capability Limitation.
Bandwidth Limitation.
Vulnerable wireless links.
Coverage Implication.
Dynamic Environment.
QoS and QoE


Technical Issues Around Mobile IPTV
SD/HD contents delivery

Middleware
EPG

Fixed-Mobile Convergence
IMS for media streaming

Fixed-Mobile Convergence
IMS for media streaming

Unexpected movement
Restricted device capability

Changeable bandwidth
Vulnerable wireless link
Weak security chain


STANDARDISATION
GSI &ITU-T FG are major organisations.

Unified MOBILE IPTV services

Congestion control capabilities.

Adapt dynamically to change in wireless net work characteristics

CONCLUSION & FUTURE of MOBILE IPTV

Development in accordance with IPTV.
Too many strict requirements to deploy IPTV.
Ensuring QoS/QoE for heterogeneous devices.
Future work “ Sophisticated Architecture.
Optimal resource allocation for large systems.
