  • 1. Market and Technology Overview Testing IPTV Services and Triple Play Infrastructure Market Overview – Triple Play Triple Play = Voice + Video + Broadband Data One service provider, one bill, one connection. Drivers - Commercial pressures: increase profits; reduce subscriber churn, reduce Opex - New enabling technologies: IPTV, VoD, VoIP, FTTx, ADSL2+/VDSL, Docsis 1.1/2.0, PacketCable, QoE, Multicast, MPLS, Carrier Ethernet… IPTV is the key component of CSP Triple Play strategy Cable (HFC) Triple Play Cable MSOs: Cable Cable - Already provide video (TV) and data service Internet TV - Advantage: high bandwidth to the customer (HFC vs copper pair) Cable - Aggressively rolling out voice service Voice - 2005, MSOs had 14 million VoIP users worldwide (Source: Probe Research) Telcos Copper Pair (DSL) Triple Play - Already provide Voice and data service - Deploying IPTV to compete with cable MSOs/prevent market share erosion Data IPTV - Biggest risk is in the last mile: - xDSL – enough bandwidth for video? - FTTx – enough budget to play the game?

IPTV: Are you getting the picture? Agilent North America Seminar: June 2006 What is IPTV exactly? • Merely television delivered over the Internet? - No! • Leverages IP technologies to deliver an enhanced TV experience in the context of Triple Play (voice, video, data) services – Whatever (diversity of content, customization of experience) – Wherever (mobility, iPod) – Whenever (VOD, PVR) • Integration with other Triple Play devices – “composite services” – Caller ID on TV – Online messaging/betting during televised sporting event • Different than current TV offerings: User created video; ad-hoc video content; much more choice and user preference in professional content – Multiple customizable camera angles during a sporting event – Personalize advertisements subscriber is interested in • “Click-to-Buy” button – Highly customized channel selection – ‘Intelligent’ channel control IPTV: Are you getting the picture?

Market Trends (Million) ($ Million) 60 $50,000 $40,000 40 $30,000 $20,000 20 $10,000 0 $0 CY04 CY05 CY06 CY07 CY08 CY09 CY04 CY05 CY06 CY07 CY08 CY09 Wordwide IPTV Subscriber Worldwide IPTV Revenue “Worldwide CY04 IPTV subscribers were at 815K; we expect continued strong growth in IPTV subscribers with CY09 reaching 53.7M subscribers; a 5-year CAGR of 133%” “Worldwide CY04 IPTV service revenue was $323.3M; we expect continued strong growth in IPTV service revenue with CY09 reaching $44.3B, a 5-year CAGR of 154%” - Infonetics IPTV Equipment and Services Outlook, 2005 IPTV: Are you getting the picture? Agilent North America Seminar: June 2006 Relevant Technologies •“Broadcast” IPTV is delivered over Multicast – A multicast group represents a TV channel – Subscriber sends an IGMP ‘join’ message to request an IPTV program – Video source sends a single video stream per channel, which is replicated by the network devices so that it reaches every subscriber who is watching that channel – Multicast replication should occur as close to the end user as possible to conserve network bandwidth • Video on Demand (VOD) is delivered through unicast • MSTV (Middleware platform and IPTV architecture ) – Key feature: Instant Channel Change (ICC): Video content is distributed via IP Multicast as in regular IPTV, but when the user changes a channel a short unicast burst of video traffic is sent from the “D-server” (Distribution Server) to the set-top box to enable a faster channel change • Access Protocols: PPPoX or DHCP to identify subscribers IPTV: Are you getting the picture? Agilent North America Seminar: June 2006 3
  • 4. Relevant Technologies MPEG-2 vs MPEG-4 • Moving picture experts group • Audio and video compression (we will discuss video here) MPEG-2 Used with Cable, DVD, Satellite (DBS), VOD – With SDTV, bitrate ~ 3.75Mb/s – Not suitable for HDTV over IP – bitrate ~ 20Mb/s MPEG-4 • 22 parts to the specification • Part 10 (H.264/AVC) deals with advanced compression techniques for video • Includes technology for digital rights management (DRM) • Enables HDTV (much better compression than MPEG-2) • Many new IPTV deployments are going strait to HDTV and thus MPEG-4 Three frame types – i-frames: entire picture. Can be displayed w/o reference to other frames – p-frames: forward predicted from an i-frame. Only represent deltas with “motion vectors” – b-frames: forward and reverse predicted from previous and next i/p frames IPTV: Are you getting the picture?

  • 5. IPTV is Driving Network Evolution • Financial rewards of IPTV are triggering the most remarkable evolution of Telco networks in this decade • Infonetics: Service Provider spending on IPTV-related services infrastructure: – 2006: will reach almost $1B – 2007: $2B – 2009: $4.5B • For example… – AT&T (former SBC) is spending over $6 billion on Project ‘LightSpeed’ IPTV and VoD services are re-shaping the network infrastructure, throughout access, edge and core networks… IPTV: Are you getting the picture? Agilent North America Seminar: June 2006 IPTV and VoD are Driving Network Evolution Video transport creates new challenges for traditional telecom networks Robust RTSP servers IPTV or VoD source Efficient bandwidth management Reliability, Security More important than ever IGMP snooping to enable Firewall or ALG efficient use of bandwidth High Availability Critical for video Routers DSLAM Switches B-RAS Ethernet or ATM Subscriber IP/MPLS Aggregation Network Authentication Dominant Core multicast traffic requires router QoS-enabled networks upgrades High-bandwidth and scalability required for access and core IPTV: Are you getting the picture? Agilent North America Seminar: June 2006 5
  • 6. Network Evolution Bandwidth and Scalability Requirements Challenges: • Traditional “Best Effort” networks need major bandwidth upgrade • To enable IPTV, 25-50 Mbps needed per subscriber (Source IPTV World Conference at NAB 2006) – Customer concurrence is enhanced dramatically; more bandwidth consumed • Fast growth in subscriber numbers; access and aggregation device overload Technologies • FTTx and new generation xDSL rolling out in the “First Mile” – Passive Optical Network (PON) technology is driving down the costs and complexity of FTTx deployment – Globally, service providers are embracing PON as an strategic step to enable “Triple Play” services (EPON in Asia, GPON in North America and Europe) • Increasing 10G interfaces in core/edge, 40G is landing • Carrier-class Ethernet is spreading “end to end” • Enhanced B-RAS or emerging EAR (establish large numbers of PPPoX or DHCP sessions) • MPLS becoming a foundation for core/edge networks IPTV: Are you getting the picture? Agilent North America Seminar: June 2006 Network Evolution Bandwidth Management Challenges P2P Traffic hogs bandwidth • Raw bandwidth is not enough for protecting service quality – Concurrent user traffic will cause congestion • P2P traffic, “all you can eat” monster, consumes up to 80% bandwidth Technologies • QoS policies must be deployed to guarantee bandwidth for revenue-critical services • Per-subscriber bandwidth management IPTV: Are you getting the picture? Agilent North America Seminar: June 2006 6
  • 7. Network Evolution Multicast Traffic Explosion Challenges • Broadcast IPTV increases multicast traffic • Large numbers of routers, B-RASs, switches and DSLAMs are not multicast- ready; low maximum multicast forwarding rates • Large numbers of B-RASs, DSLAMs, switches have poor IGMP leave/join handling performance, which causes large IPTV channel zapping delays • Poor multicast routing performance is a barrier for routers Technologies • Enhance multicast forwarding performance of network devices • Enhance IGMP performance of B-RAS, EAR, DSLAM to improve channel zapping delay • Improve multicast routing performance IPTV: Are you getting the picture? Agilent North America Seminar: June 2006 Network Evolution Reliability and Security Challenges • High Availability (HA) was required by Telco voice, now is also adopted for Triple Play service providers – Ensuring “five-nines” (99.999%) IP network reliability is challenging • DoS attacks and spam threaten voice, video and data services over IP Technologies • Deploy HA protocols: Graceful Restart, Non-stop Forwarding, MPLS Fast-reroute • Ensure performance and functionality of firewalls and intrusion prevention devices • Adopt application layer-aware devices IPTV: Are you getting the picture?
