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

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

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)

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
