  • Case Study:DTT (Digital Terrestrial Television) Warsaw, February 2004

    Roberto de Martino Autorit per le Comunicazioni

  • IndexAGCOM IntroductionItalian TV market overviewDTT technical aspectsRegulatory FrameworkConclusions

  • AGCOM IntroductionSection 1.

  • AGCOM IntroductionAGCOM (Autorit per le Garanzie nelle Comunicazioni) established by Law n. 249/1997Council assisted by two Commissions: networks and servicesRegulatory Authority for both Telecommunications and audiovisualConvergent AuthorityResponsabilities also in press and publishing sectors

  • AGCOM IntroductionAGCOM activities and responsabilities:InterconnectionVerification of dominant position (TLC, TV)Accounting separationUniversal serviceAudiovisual frequency planTV monitoringNumbering PlanItalian PNRF (official comments to Tlc Ministry)

  • AGCOM IntroductionAGCOM activities and responsabilities :TarifsMobile market competitionServices qualityTV-SATPolitical pluralismAdvertising, Audiovisual production quotaPress

  • CONTENTSTRANSPORTBROADCASTRegulatory interventions: Decoder unicoDISTRIBUTIONRespect of programmation quotas and of production contentPublicity quotasMinor tutela, Information ecc., Licencers and authorizations, Antitrust rules etc

  • Italian TV market overviewSection 2.

  • Italian TV market overviewGENERAL INFORMATION:11 national terrestrial channels +600 local TV, +1000 radioAbout +2,5 milions satellite pay-TV subscribers1 satellite digital platform (SKY) Cable Tv: strong growth switch off (ATO) date: end 2006Previous Tele+ frequencies have been sold to a consortium (Ben Amar/TF1) to give birth to Sport Italia (Europa TV) and D-free (Prima TV)

  • Italian TV market overviewRECEPTION PATTERNS:

    Households: more than 20 millionsTerrestrial Tv: 88/89% (50% EU average)Satellite Tv: 10/11% (21% EU average)Cable Tv: 1% (29% EU average) Terrestrial analogue TV still dominates the market

  • Italian TV market overviewTV SERVICES:Terrestrial FTA: Two major national players (RAI, Mediaset), strong local characterSatellite Pay-TV: One main Pay-Tv operator SkySatellite FTACable TV: optical fiber, and ADSL

  • Italian TV market overview

  • Italian TV market overview DIGITAL OFFER: Total Digital TV penetration: 12/13% (EU average 18%)DTH: 12/13% (EU average 12%)DTT: trials/experimentation (EU average 1-2%)Cable: 0.1/0.2 millions HH (EU average 4%)

  • Italian TV market overview: Alternative services to analogue terrestrial Tv

  • Italian TV market overview CONCLUSIONS ITALIAN TV MARKET MAIN CHARACTERISTICS:

    Analogue terrestrial TV still dominates the marketPresence of 2 strong national operators which own 3 TV channels eachStrong presence of local operators (more than 600)Vertical model in the analogue terrestrial TV (the operators manage the transmission capacity, own the frequencies, content production, advertising ecc.)

  • Italian TV market overviewCONCLUSIONS ITALIAN TV MARKET MAIN CHARACTERISTICS:Satellite Pay-TV is the strongest alternative so far to conventional analogue terrestrial TvDigital penetration is in the EU averageStill weak penetration of cable TV (even with quick growth and ADSL coming soon)New entries in the Italian broadcast marketDTT started (5 Mux, +20 programs)DTT expected growth (switch-off set end 2006)

  • DTT Technical aspectsSection 3.

  • DTT Technical AspectsDTT BENEFITS:Better Picture/sound qualityIncrease capacity and efficiency of networksReduce transmission costsBetter spectrum efficiencyLower entry barrier, increased competition

  • DTT Technical AspectsDTT Play-out elements:EncoderMultiplexerOFDM ModulatorEPGCA

  • DTT Technical AspectsDTT distribution network:SFNMFNNetwork adapter

  • DTT Technical AspectsAnalogue frequency TV Plan (Analogue PNAF):Issued in 1998 by AGCOMAGCOM Delibera n 68/98Two level plan approach:First level plan- optimization of resourcesSecond level plan- once completed the first level plan optimization (integration) of left resources

  • DTT Technical AspectsANALOGUE TV PLAN REQUIREMENTS:VHF frequency band (I and II) UHF frequency band (IV and V)45 channel (frequency) available in UHF band for planning6 channel (frequency) available in VHF band for planningTotal: 51 channel (frequencies)

  • DTT Technical AspectsANALOGUE TV PLAN REQUIREMENTS:Quality objective: 4 on the ITU-R scaleOne third of capacity to be reserved to local programmingUtilize European channelization in VHF bandTerritorial coverage objective: 80% of the Italian territory (with inclusion of all Italian capoluoghi di provincia)Power > 200 WTransmission infrastructure positioned on the same position (site)Total number od transmission sites: 480

  • DTT Technical AspectsANALOGUE TV PLAN (I LEVEL) RESULTS:3 channels (frequency) per TV networkNational coverage with 17 TV channels6 TV channel reserved to local TV11 TV channel reserved to national TVAll requirements set satisfied

  • DTT Technical AspectsANALOGUE TV PLAN (II LEVEL) REQUIREMENTS:II level TV plan total number of sites: 480Constraint regarding maintenance of coverage established in the I level TV planPower greater than 200 WRegional coverage areaProvincial coverage area

  • DTT Technical AspectsANALOGUE TV PLAN (II LEVEL) RESULTS:AGCOM Delibera n 95/00/CONS126 regional area covered1502 provincial area covered

  • DTT Technical AspectsDIGITAL TV PLAN REQUIREMENTS:Quality objective: 95% service probabilityOne third of capacity to be reserved to local programmingUtilize European channelization in VHF bandTerritorial coverage objective: 80% of the Italian territory (with inclusion of all Italian capoluoghi di provincia)Transmission infrastructure positioned on the same position (site)260 planned sites

  • DTT Technical AspectsDIGITAL TV PLAN (I LEVEL) RESULTS:3 channels (frequency) per TV network (multiplexer)National coverage with 17 TV channels6 TV planned network (multiplexer) reserved to local TV12 TV planned networks (multiplexer) reserved to national TV64 QAM better exploits available resourcesAll requirements set satisfied

  • DTT Technical Aspects DIGITAL TV PLAN (II LEVEL) REQUIREMENTS:II level TV plan total number of sites: 260Constraint regarding maintenance of coverage established in the I level TV plan16 QAM (more robust)Power greater than 200 WRegional coverage areaProvincial coverage area

  • DTT Technical AspectsDIGITAL TV PLAN (II LEVEL) RESULTS:AGCOM Delibera n 399/03/CONS126 regional networks served1272 provincial networks servedToal number of served networks: 1398

  • DTT Technical AspectsExample: Spectrum BenefitComparison between terrestrial analogue TV and DTT planning based on the analogue TV plan (PNAF) and digital TV plan both developed by AGCOMPlan resources: 51 (54 in the digital case) TV channels 6 TV freq. channels VHF-III band45 (48 frequencies in the digital case) TV freq. channels UHF-V band

  • DTT Technical AspectsPlanning Exercise Results:

    National TV ProgramRegional TV ProgramsTotal Tv Programs (National and Regional)Analogue11126137DTT48/60 (12x4/5)378/504 (126x3/4)426/564

  • DTT Technical AspectsPlanning results:DTT multiplies the resources (program number) by a factor of 4/5 in the case of national programsDTT multiplies the resources (program number) by a factor of 3/4 in the case of local programs

  • DTT Technical AspectsDecoder definitions:Zapper: only conversion between TV analogue format and digital TV formatInteractive decoder: enhances zapper because it allows the user also to utilize interactive applicationsiDTV: it combines in the TV set the decoder functionalitiesCA: for pay-TV applicationsAPI: tied to interactivity (operating system analogy for PC)

  • DTT Technical AspectsDecoder market:+ 40 Million TV sets+ 20 million HouseholdsZapper price: about 150 Euro (25% marin)Interactive decoders price: about 300 Euro (25% margin)

  • DTT Technical aspectsApplication Program Interface (API):MHP platform has been chosen by the biggest broadcast operatorsMHP Applications in terms of enhanced TVMHP applications tied to interactivity for regional/local/government services

  • DTT Technical AspectsInteractivity:Program-tied interactivity to enhance program contentT-learningT-government in collaboration with local entity, University, Tegion and Public AdministrationApplication: On-line bet marketReturn channel: wireless or cabledSIM card (to identify user requesting a certain service)

  • DTT Technical AspectsMajor broadcasters have invested in DTTInvestments cover head-end and regional hubs, distribution network and transmission networkAs a rule of thumb: 45% transmission network, 35% distribution network, 15/20% play-out (head-end)

  • DTT Technical AspectsDTT started with:DTT networks operatingMulticast of same programs available in terrestrial analogueMulticast (satellite) of other programsSome (still limited) new editori
