    • The Greater Chicago Chapter SCTE - IPTV Overview Content Providers
    • IPTV Content Providers Who are they? Hulu, Netflix, Vudu, CNN, ABC, Sony, Disney…… What are they doing? Delivering content directly to consumers via the Public Internet 21
    • In July, 33.5 Billion Minutes per Month were Spent Watching Video Online Total Minutes Watching Online Video per Month At Home, Work, and Universities 3 3 .5 (in Billions) 3 2 .6 3 2 .3 30 2 8.8 2 7 .0 2 4 .6 20 2 0.8 1 8.3 10 1 1 .0 8.9 6 .9 0 Ju n -0 5 Oct -0 5 Ma r -0 6 Ma r -0 7 Ma y -0 7 Sep-0 7 Nov -0 7 Ja n -0 8 Ma r -0 8 Ma y -0 8 Ju l-0 8 YouTube accounts for over one-third of all time spent watching online video Source: ComScore 22
    • Just 9% of Those Who Watch Video Online Strongly Agree that they Watch TV Less Often Using aa 1-10 scale with 10 being strongly agree and 1 being strongly disagree, how much do you agree or disagree Using 1-10 scale with 10 being strongly agree and 1 being strongly disagree, how much do you agree or disagree with… since I I began watching video online I now watch TV less often with… since began watching video online I now watch TV less often Watch TV Less Often Since Watching Video Online (1-10) Watch TV less (4-7) often - strongly 17% agree (8-10) 9% Strongly disagree (1-3) 74% Results are similar to last year 16% of men age 18-34 who have watched video online strongly agree that they watch TV less often now – compared to 6% of all others From LRG study Emerging Video Services II 23
    • IPTV Content Providers – Problems Content protection Content monetization models Diverse content format requirements Network performance 24
    • IPTV Content Providers – Business Issues Losing Ad revenue to online advertising Thus Hulu Losing viewers to alternate consumption models ie Netflix challenged by VOD Fragmented market with content explosion The dreaded “long tail” 25

    • The Greater Chicago Chapter SCTE - IPTV Overview IPTV for Cable
    • IPTV for Cable Does Cable need to jump on the IPTV bandwagon? Is it “IPTV”, Video over IP, or Video over the internet? What’s involved? Where can we assist? 41
    • IPTV for Cable – Business Issues Losing Subscribers to Telcos Loss of revenue to Over-the-Top services Limited number of suppliers / perceived cost issue Slow addition of consumer applications 42
    • MSO Perception Comcast: “IPTV is coming and it will likely be big”* Comcast content (and Internet) to PC and eventually any IP client Comcast (and all MSOs) migrating to >> narrowcast 80% of spectrum digital in 3-5 yrs Considerable new spectrum for HD and SD digital services At least 50% unicast + multicast Serving group sizes continue to shrink 3-5 yr expectations 80% of spectrum digital >50% unicast & multicast IPTV via DOCSIS pipe requires up to 30x CMTS growth Solution needed to match MPEG/QAM video costs Unified CPE MPEG/QAM and MPEG/IP STB/Gateway converts QAM↔IP * July 2008 NGNA Kick-off 43
    • MSO Perception TWC: “The VIP architecture is intended to augment the existing video distribution network to allow the delivery of TWC video services to non-traditional devices (ie: PCs, personal media devices, cellphones, IP STBs, etc)” “The intent is to deliver live broadcast/linear video and video on demand services to IP STBs where those IP STBs do not contain RF tuners but instead use only an Ethernet port” *July 2008, Video-over-IP RFI 44
    • IPTV for Cable – Solutions MPEG-2/RF to IPTV in Four Stages Ecosystem Evolution Internet applications via cable MSO licensed content to IP clients • PCs, IP STBs, Handhelds Integration of IP Set Tops into the cable ecosystem IPTV 2.0 • Sharing of content between networks and “three screen” devices 45

    • Transport Gateway Current CPE development that can act as MPEG and DOCSIS termination 8 MPEG or DOCSIS tuners Multiple LAN and device interfaces DLNA protocols DRM bridge to IPRM or DTCP Video distribution solutions within the Home Net exist for either MPEG or DOCSIS delivery of IP video Solution could provide a flexible platform for serving both MPEG video and IP video/data with IP distribution over the over Home Net 51
    • DIBA is Essential to IP-VOD and IPTV for Cable DOCSIS IP-video Bypass Architecture • The standard digital broadcast is distributed over an IP backbone. • Video packets go a last-hop router/switch and then directly to the EdgeQAM and HFC plant • Typically, IP/DOCSIS content goes through the CMTS core • CMTS core processing is at least 4 times as expensive as EdgeQAM processing • With DIBA, IPTV and IP-video same path as digital broadcast • DIBA bandwidth cost -> digital video bandwidth cost 52
    • Cable Network with IP Backbone, IP/DOCSIS service and Digital Video Service DOCSIS 3.0 allows multiple Internet downstream channels to single TV Cable Model feed DOCSIS Channels Upstream Cable Modem Primary (MAC enabled) Local Edge Termination Router System Non-Primary Network VOD (CMTS) Non-Primary Server Video/IP Multicast Common IP DOCSIS Digital Video Carriers Backbone MPEG Cable Network Edge-QAM Modem (RF modulator) Digital Set-top PC DOCSIS: Data over cable service interface specification TV 53
    • DOCSIS Bandwidth via Modular CMTS Architecture is more expensive than Digital Video Internet TV feed Integrated DOCSIS Channels CMTS Primary Downstream Edge Local Router Tunnel Downstreams Network DOCSIS VOD Edge-QAM Server (RF modu- lator) DOCSIS 3.0 CM • Modular CMTS architecture introduces DOCSIS Edge-QAMs IP set-top • Allows additional downstream channels to accommodate IP-video and IPTV without adding additional upstreams • IP-video packets still transit the CMTS and edge router (twice) • Additional cost compared to digital video TV • Tunnel from CMTS to Edge-QAM 54
    • DOCSIS IP-video Bypass Architecture (DIBA) Reduces the cost of Digital Video Internet TV feed Integrated DOCSIS Channels CMTS Primary Downstream Edge Local Router Non-Primary Downstreams Network DOCSIS VOD Edge-QAM Server (RF modu- lator) • IP-video packets follow the same path as digital video DOCSIS 3.0 CM • Edge Router to Edge-QAM modulator to customer • Unicast flows tunnel from router to Edge-QAM (which is IP set-top not a router) • Multicast IPTV sessions are joined by the Edge-QAM (just like in digital video) • Edge-QAM performs the necessary DOCSIS encapsulation TV • DOCSIS channels from Edge-QAM are ‘non-primary’ meaning they do not have full MAC layer functionality 55
    • IPTV on DOCSIS with DIBA • Similar issues to Switched-Digital-Video 56
    • Channel Popularity (i.e., …NBC, CNN, ….TOON……) Average Number of Subs Viewing Each Title Network Popularity Rankings 57
    • To conserve Bandwidth, IPTV is ‘Switched’ just like Switched Digital Video The MSO wants to offer more networks (CNN, FOX, …) than will physically fit into the available bandwidth The most popular titles (FOX, CNN, etc) are transmitted across the entire plant from one set of ‘broadcast’ modulators. This is the standard approach to digital broadcast. In addition, the plant is divided into serving areas (MAC domains), with sets of dedicated modulators for each serving area. These dedicated modulators are used for the SDV titles. The less popular titles (TOON, TVLand, etc) are switched. These titles are only transmitted to a serving area (“switched on”) if at least one STB is tuned to that service. 58
    • All Broadcast – Requires Too Much Bandwidth All services go to all service areas, regardless of whether anyone is watching those services. IP Multicast over Metro Network Digital video over HFC plant All shows, all nodes, all the time Video from satellite feed and servers APEX APEX Switch APEX 59
    • Switched Digital Video – Conserves Bandwidth For switched services, only the services being watched in a particular service group are transmitted. IP Multicast over Metro Network Digital video over HFC plant Video from satellite feed and servers 60
    • Total SDV titles to each serving area, versus number of active subs. SD+MPEG2 Computed Channels Viewed Average Transmitted Titlesarea Serving Area 140.00 Comparison to all uni-cast transmission to each subscriber: 120.00 100 viewers require 100 separate transmissions 100.00 per Saved spectrum = “benefit” SDV titles per serving 80.00 60.00 Having multiple viewers per ‘show’ saves spectrum compared to all unicast 40.00 • Drives network toward large serving areas • Uses up more spectrum 20.00 More and smaller serving areas 0.00 0 200 400 600 800 1000 1200 1400 1600 1800 Activeviewers per serving areaServingMPEG2 Active Viewers per with SD and Area 61
    • “Cost” = Number of ‘extra’ QAMs required due to same SDV content being transmitted to multiple serving areas "Extra" QAMs versus plant segmentation by different modulators for target blocking probability) (based on allocated QAMs 3500.00 Cost =Extra QAMs required Required Mean usage Allocation for target blocking probability 3000.00 2500.00 Extra QAMs 2000.00 1500.00 Limited spectrum for all ‘shows’ means size of serving area is also 1000.00 limited • Less than the entire plant 500.00 More and smaller serving areas 0.00 0 50 100 150 200 250 300 Segments Number of Serving Areas 62
