WHAT IS HBBTV?
HbbTV is and ETSI standard describing how DVB broadcast signals can be used
to trigger interactive services over internet on connected televisions.
HbbTV exists due to close cooperation of broadcasters with CEManufacuters.
Broadcasters control the available services that relate to their channel and can
therefore interact directly with their audience.
Less test implications for CE-Manufacturers to support popular broadcast
interactive (catch-up) services.

WHAT HAS HBBTV TO DO WITH DASH?
-
HbbTV 1.5 prescribes MPEG DASH for playout of on demand files
-
HbbTV V2 refers to parts of DVB-DASH (still in the make) but will support
both live and on demand playout
Other pillars of HbbTV V2 besides MPEG DASH:
- DVB-CI+ 1.4 support for CI+ cards
- Second screen synchronisation using work done in DVB-CSS
- HTML5 profile replacing CE-HTML
Expected release of HbbTV V2: July 2014
TEST ENGINE FOR
ENCODING
COOPERATION BETWEEN DASH-IF, EBU
AND GPAC LICENSING
TEST ENGINE FOR ENCODING
The test platform is expected to act as 'reference software workflow‘ for creating
different audio/video formats in the contribution/distribution production chain
using only Open Source Software.
It is intended in first instance to facilitate the discussion about suitable MPEGDASH content generation (including encoding and packaging settings) for
different use cases.
Members of EBU, DASH-IF and in the future other standardisation groups like
HbbTV and DVB can create encoding / packaging settings with the goal to
create reference files. This should accommodate the discussions around
implementation of specifications and standards
