Hybrid Broadcast Broadband in Italy: from the past to the future
Hybrid Broadcast Broadband in Italy: from the past to the future Giovanni VENUTI Telecom Italia 1 Once upon a time • • • In October 2009 DGTVi published the so-called «Broadband Addendum» to HDFI HD-Book DTT 1.0. Actually, the first public HBB specification in Europe. The year before LA7, at that time part of Telecom Italia Group, had launched la7.tv, a catch-up TV service for PCs: through a neat point&click Flash UI (day of the week/program grid) users were able to access on demand from their web browser almost any content aired by LA7 on DTT over the past 7 days The team supporting LA7 at Telecom Italia R&D centre (TIlab) was challenged to provide the same service with the same UX, the same metadata and the same content assets (MP4 files) on BA-compliant devices 3 La7ondemand 4 How the story unfolded • • • • In May 2010 La7ondemand was showcased at V DGTVi National Conference in Milan, both on a Telesystem TS7900HD STB and a LG TV set. In June it went in operation on DTT (barker channel 777), in December on Tivùsat. A few months later the possibility of launching La7ondemand directly from channel 7 was added. In December 2012 Telecom Italia introduced on DTT barker channel 999 a version of Cubovision OTT service for BA-compliant devices In February 2011 Mediaset launched Premium Play, a full-fledged multiscreen OTT complement to their Pay TV service, available also on BAcompliant devices, including their own POD Then Rai followed with RaiReplay catch-up TV service and more … In July 2014 CRTV announced broadcasters’ plans towards HbbTV 2.0 5 DTT Platform specs timeline HDHD-Book DTT 2.0 HDHD-Book DTT 1.0 D-Book 1.0 Sep’04 LCN CI v.1 for TVs Apr’07 HDHD-Book DTT 3.0 Broadband Addendum D-Book 1.1 HD (H.264/AVC) Ethernet CI+ for TVs MHP 1.1.3 DVB-T SD (MPEG-2) V.90 modem MHP 1.0.3 HDHD-Book DTT 2.1.1 DVB-T2 3D (2D bc) OIPF HAS GEM 1.3 HBB profile CENC OIPF DRM API MPEG-DASH BAS framework CI+ 1.3 Jan’11 Nov’12 OIPF PAE HTTP streaming Oct’08 Oct’09 Updated T2 profile HEVC EBU-TT-D DVB-DASH OTT UHDTV OTT PC (CAD) Oct’14 6 SAT Platform specs timeline HDHD-Book SAT 1.0 S-Book 1.0.3 HDHD-Book SAT 2.0 HDHD-Book SAT 3.0 Broadband Addendum DVB-S SD (MPEG-2) LCN V.90 modem MHP 1.0.3 DVB-S2 HD (H.264) Ethernet CI+ for TVs MHP 1.1.3 HBB profile 3D (2D bc) CENC OIPF DRM API MPEG-DASH BAS framework CI+ 1.3 HEVC EBU-TT-D DVB-DASH OTT PC (CAD) UHDTV Oct ‘12 Dec‘14 OIPF PAE HTTP streaming Dec ‘08 Oct ‘09 Mar ‘10 What’s next? • • • Convergence with HbbTV 2.0 started earlier than CRTV announcement • HD-Books and HbbTV share the same HBB roots (OIPF PAE vs DAE) • HbbTV 2.0 and HD-Books 3.0 aligned on key new features (HEVC, DVB-DASH, EBU-TT-D Subtitles) HbbTV Working Group active within HDFI since 18/11/2014 on • Migration plans and activities • HbbTV 2.0 profiling • Missing features to be possibly included in next HbbTV versions HD-Books 4.0, to be released during 2016, should include: • HbbTV 2.0 with enforcement of some optional features (e.g. CAD) • UHD-1 Phase 2 (subject to completion of related DVB work) • CI+ 1.4.1 • FTVA specs (e.g. RCU) 8 A thorny matter: Content Protection and Application Security • • • • HD-Books so far bound to neutral choices: • CIPlus and CENC for content protection • BAS framework for application security Verticalization left to operators • Mediaset Premium with Nagra and their own specs • Tivù with CPAS (Marlin DRM and BAS certificate regime) Different approaches in other countries • PlayReady/Marlin DRMs mandatory simulcast in France • PlayReady DRM mandated in new Freeview Connect initiative The whole matter is going to be revisited in the scope of HD-Books 4.0 9 Hybrid Broadcast Broadband in Italy: from the past to the future Giovanni VENUTI Telecom Italia 10 Hybrid Broadcast Broadband in Italy: from the past to the future Giovanni VENUTI Telecom Italia 11
