2 Digitalization of Video contents is changing the Television Models Video from Analog to Digital New content formats, high definition, compression algorithms are driving the digitalization of the network making TV delivery interactive and high quality From Video to File Each Production Center creates new Digital Contents with the possibility to customize according to different diffusion ways and to include interactivity and advertisement From Video Network to Multi-service Network Looking for new business opportunities TV Operators invest in new services (Virtual Network Operator) or new business model (leased capacity, network sharing) along with its traditional core business 2 Alcatel-Lucent
3 Digitalization of Video contents is changing the Competitive Marketplace COMPETITIVE TRANSFORMATION TV Broadcaster & Cable Operators enter TELEVISION..enter VOICE and DATA None Weak Fierce COMPETITION Timescale Fixed & Mobile Telco 3 Alcatel-Lucent
4 Sailing into the right direction.. COMPETITIVE TRANSFORMATION Necessary Response Service Transformation Traditional Approach Thought Leadership From To Single Service Video (TV) - Voice (Telco) Multi Service Video,Data,Voice 4 Alcatel-Lucent
5 The Building Blocks of Digital Video Networks Efficient and real-time contents processing and exchange to head-ends Reliable digital transport network to pave the way to new services provision Diffusion way to reach as many end users as possible 5 Alcatel-Lucent
6 Challenging TV business as a result of increasing competition COMPETITIVE TRANSFORMATION Challenges Television Challenges TV Operators From the traditional TV to new media Digital TV (interactivity, HD) CATV (pay per view) IPTV (TV on demand) Mobile TV (new contents) New Television Networks requires best in class and state of the art telecom technology TV Broadcasters have different telecommunication business model and can rely on: Wireless Microwave With leased telecommunication (LL, VPN or lambdas) Managed Networks from a Telco With owned Optical fiber Selection for Right Transport Technology for Digital Video Networks is not easy 6 Alcatel-Lucent
7 Choosing the Right Transport Technology Telecom Transport Technology Comparison Up to 512 kb/s Satellite ASI - SDI copper Up to 100 Mb/s ATM Microwave SDH Up to 600 Mb/s ASI - SDI IP Ethernet MSTP Up to 40 Gb/s WDM Up to 1 Tb/s Video Data Transport Technology Bandwidth Capacity Alcatel-Lucent is the ONLY telecom vendor that owns ALL technologies 7 Alcatel-Lucent
8 With Digital Microwave licence Available bandwidth is only 155Mb/s and video circuits must be optimized ASI-SDI 270Mb/s must fit in 155Mb/s telecom frames Mapping Options: 34 or 45Mb/s TDM fixed bit rate Low efficiency GFP-F mapping on VCx-v (NG-SDH) Highest efficiency Circuit oriented Highest reliability (traffic segregation) Highest security Gigabit Ethernet High flexibility High reliability only with MPLS (high bit rate) Contribution Network Typical Rates from 1,5 to 100 Mbit/s (dual) unidirectional point to point path Distribution Network Typical Rates from 18 to 24 Mbit/s unidirectional point to multipoint path Mux Multiple of 155 Mb/s Digital Microwave Link Mux NG-SDH with GFP-F mapping on VCx-v offers best in class and more efficient digital video transport technology for Contribution and Distribution Networks 8 Alcatel-Lucent
9 With leased lines Video are circuits and Leased Lines can be virtual Telecom Service Providers offer for LL is different in the countries. GbE LL in average are cheaper but need QoS Business Model: Telecom SPs invest in QoS and TV broadcasters invest on flexibility unicast - multicast Video Signal Video Signal Video Signal MPEG Enc. MPEG Enc. MPEG Enc. ASI/IP ASI/IP GbE GbE Corporate IT Corporate Video IPTV ASI/PDH/SDH IP-MPLS GbE GbE GbE IP-MPLS VLL Optical VPN Optical Transport Optical VPN Optical Transport Telecom SP implements the L3 VPN and provides high reliable MPLS links Telecom SP implements the L2 VPN with Multi Service Optical Transport TV broadcaster implements Video circuits and FTP and Data virtual services Optical VPN for best in class unicast and multicast Digital Video Circuits IP-MPLS for highest Quality of Service differentiation 9 Alcatel-Lucent
10 With lambda services inter studios Lambda services offer highest bandwidth and transparent services Lambda services enable Centralized Real-Time graph facilities connected over distance WDM technology supports ASI, SDI, HD-SDI as well as Ethernet, ATM and SDH Each WDM lambda can transport up to 40Gb/s (100Gb/s in the future) Real time Contribution Telecom SP offer L0 transparent services Primary Distribution Corporate IT Network Content IP Network Content Storage Disaster Recovery λ Lambda Services boost inter-studio connectivity with significant low delay and high quality available in native definition 10 Alcatel-Lucent
11 With optical fiber inter studios The owner of a dark fiber or the right of use can implement any telecommunication technology to optimize the operational costs for Video and IT From different Head-ends to a Centralized Real-Time graph facility Share contents and files Create hot stand-by head-ends and distribution sites Implement business continuity or disaster recovery sites Extension of the local area network over distance The business case turn positive when the transmission overpass 10Gb/s Storage Voice Storage Video Data 32λs Metro DWDM supports 32 protected (or40gb/s) Metro CWDM supports 8 protected (or 10Gb/s) Optical fibers let TV broadcasters independent from telecom Business case turn positive after 10-20Gbit 11 Alcatel-Lucent
12 With national optical network Owner of the telecom network must guarantee: Continuance Operation of Telecom Services Appropriate SLA to each user Integrity and security of data flow Owner of telecom network implements services for: Content Studios Video Production Regional Video Distribution IT Corporate IPTV Corporate Video Etc. Services layer Transport Layer Key Attributes of Transport Regardless of Technology (circuit or packet) Deterministic and efficient Reliable and secure Simple to manage NG-Transport Networks Private Networks are the first TV broadcasters step in the telecom world for Internal Video Services, Corporate IT and external? 12 Alcatel-Lucent
13 Designing a national optical network for Video Services Real time Contribution Multi service platform Service Router WDM Transport Switch Layer 3 Layer 2 Layer 1 Primary Distribution Corporate IT Network Content IP Network Content Storage Regional Node Regional Node Regional Node Regional Node Regional Node IPTV IPTV Main Production Center Regional Node Regional Node Hot standby Production Center IPTV IPTV Lean IP DVBC DVBH Distributed L3 over WDM Transport Networks 2007 To IP and beyond! Centralized L3 over L2 Transport Alcatel-Lucent has both Solutions and supports Customers in this critical phase 13 Alcatel-Lucent
14 Designing an national optical network for Video Video needs (unicast or multicast) circuits Telecom Services (voice and data) moves to IP Telecom technology is moving to lean IP Service L3 Layer Responsible for the SLA of each user of the network Transport L2 Layer Responsible for the integrity of data transmitted over a telecom network Network optimization achieved by managing bytes at the lowest layer possible that satisfies Quality of Service and end-to-end connectivity requirements IP Services Optical Networking Transport Protocol Stack Layer 3 Layer 1.5 & 2 Layer 1 Layer 0 20% 40% 100% Cost (CAPEX) per managed byte normalized to total protocol stack cost up to Layer 3 cross-connect where you can, switch where you need, route where you must 14 Alcatel-Lucent
15 Conclusions Voice and Data are entering in the TV or TV is entering in the voice and data world? Video Digitalization compels a strong innovation in the telecom world and creates new content formats, high definition, and interactive TV Telecom Operators enter the Broadcasting Market offering Mobile and IP TV TV Broadcasters invest in telecom to secure their main content asset optimizing Digital Microwave networks or even investing in optical fiber New TV networks can support content contribution and distribution, as well as DVB-x, IPTV and other services Alcatel-Lucent experience in the Telecom and TV World supports TV operators implementing profitable telecom networks in competitive world of digital video 15 Alcatel-Lucent
