1Some Numbers


Current IPTV Subscribers Worldwide

• Analysis of Point Topic in Q4 2009 shows total 26 million subs worldwide.

• It was 15 million subs in Q4 2008, which means % 73 growth.

• SNL Kagan Analysis shows IPTV subs. Worldwide may reach 59.7mn by 2013


Alcatel-Lucent: Unmatched Field Experience in Video Network Integration

North America Asia & PacificEurope, Middle-East, Africa,

Latin America

South America

1200 + Video Experts, 2800 System Integrators, 10,000+ Service Experts, presence in 130 countries

>100 projects worldwide

Over 7M active users on IPTV installed base, with largest implementation over 2M STBs


Alcatel-Lucent’s Share in IPTV Market

•MRG’s Global IPTV Market Leaders Report shows; in the IPTV Access sector, Alcatel-Lucent was found to hold a 51% share of the worldwide access market, as well as furthering its strength as a systems integrator and holding the number two position in the global middleware sector behind Microsoft (which ALU works as primary E2E integrator).


2Why IPTV ?


Service Provider Side of the Picture

• Triple Play / Convergence : High Speed Internet, Voice Over IP and IPTV using the same IP backbone. (ALUs TPSDA)

• Even quadruple play : Mobile phones Wifi/GSM aware used at home utilizing the VOIP service at home. (flat rate)

• Service providers with triple play offering wants to offer you all these services with just one access link (xDSL,FTTH...) and IPTV is a major part of this strategy.

• AT&T ‘s $4 billion Lightspeed project is an example. ($6 billion more investment in upcoming 5 years)

• As every service is under the control of single entity (Service Provider) ensuring SLA for all these services with QoS is easy.


Customer / End User Side of the Picture

• Competive and flat prices for end users on bundles including all these services. (HSI,IPTV,VOIP)

• No need for extra installation like satellite dish,lnb, motors etc... Mostly utilizing the old access networks. Even STBs (set-top-box) can be replaced by media centers, PCs , gaming consoles like XBOX 360.

• Single customer service point responsible for all these 3 services.

• Plus the fancy features of IPTV :

• Interactivity (Connected,social)

• PVR - Personal Video Recorder , NPVR – Network PVR, Timeshift Restart

• Watch as you need (PPV- Pay per view, VOD – Video on Demand)

• All IP Based applications can be accesible from TV. (For eg. Receive notification when you get email, IM messages etc.)


3How IPTV Works ?


WebTV – IPTV Difference

•Different Platforms

• Web - Public Internet

• IPTV – Secure dedicated private networks

•Georaphical Reach

• Web – Entire Internet

• IPTV – Service Provider network

•Ownership of Network Infrastructure

• Web – Internet no Qos quarantee

• IPTV – SP Network – High quality experience

IRD - Integrated Receiver Decoder or Descrambler

•IRD Tunes into the frequency and outputs a single service stream.

•Uses the CA – Conditional Access Module to Descramble Encrypted content.


Encoders - Mpeg Encoding Primer

•GOP – Group of Picture

• I Frames : Snapshots of picture – Full Image Data

• P Frames : Delta Information - Approx %40 of image data

• B Frames : Predections of how objects moved. Checks forward P frame and backward I frame, contains vector information – Max %25 data


Encoders - Mpeg Encoding Primer

•Currently used encoding technologies in IPTV : MPEG2, MPEG4 – AVC (H264) and WM

•Output of IRD (Input of Encoder) :

• SDI Bitrate : 360 Mbit/s

• HD-SDI : 1.485 Gbit/s

•Output of Encoder - Bitrates :

• SD Channel : 3,0 Mbps

• HD Channel : 9,5 Mbps

• PIP Channel : 0,26 Mbps

• Radio : 0,25 Mbps


IP Network and Multicast

•Core network of the SP has high bandwidth but access side we have limited bandwidth. (For eg. ADSL2+ have Max 25 MBps)

•If you put 1HD Channel – 1 VOIP Stream – 1 Mbit HSI that means approx 10Mbit per household.

•Without multicast the access network is oversubsrcibed by all the channels.

•With IGMP – Internet Group Management Protocol aware network the edge devices only send the multicast needed to the end-users.

•Most Service providers use IGMPv2 and IGMPv3 with SSM deployments.

•Inside the customer network specific protocols like PIM,DVMRP,MOSPF etc..

•Prioritization is done by QoS mechanisms.


Multicast Primer

•Class D - Multicast (224.0.0.0 – 239.255.255.255)

•Address resolution 1-1 mapping not ARP

•IGMPv2(RFC2236) Messages :

• Join/Report

• Leave

• Query

•PIM

• Dense Mode

• Sparse Mode


Access Networks


Residential Gateways

•RGW = Last network point

•External Interface (DSL,Fiber etc..) – Differantiation of traffic via VC (virtual circuit)

•Internal Interface / LAN (Mostly Ethernet, HPNA : Coax or Phone cables)

•Externel – Internal Connectivity

• Bridge Mode

• Routing Mode / NAT (Network Address Translation)


4Demo


It’s Easy

•HD(above 100) and SD Channels(below 100)

•ICC

•EPG with PIP

• Both the full screen video and PIP window are delivered as separate PIP streams (1.5 Mbps for SD, 6 Mbps for HD and 120k for the PIP stream)

•Program Info

•Short EPG with PIP


ICC


It’s Personal

•Favorites

•DVR

•VOD

•SVOD

•Multiview (VOD Extras)

•Search

•Parental Controls


It’s Connected

•Multimedia App Environment : Sports App

•News

•Home Media Sharing


It’s Social

•Personal Portal

•XBOX Integration
