HBBTV System

HbbTV (Hybrid Broadcast Broadband
TV ) is a new industry standard that
seamlessly combines TV services delivered
via broadcast with services delivered
via broadband and also enables access
to Internet only services for consumers
using connected TVs and set-top boxes.
Services delivered through HbbTV include
traditional broadcast TV channels, catch-
up services, video-on-demand, EPG,
interactive advertising, personalisation,
voting, games, social networking and other
multimedia applications.
HbbTV applications are available on
channels where they are signalled by the
broadcaster. The broadcaster marks one
application as "autostart" and this one
is started by the platform automatically.
The autostart applications are generally
launched with a small red button icon to
notify the user that there is an HbbTV
application on that channel. Press the red
button to open the application page. After
the page is displayed you can go back to
the initial red button icon state by pressing
the red button again. You can toggle
between the red button icon mode and
full UI mode of the application via pressing
red button. It should be noted that the red
button switching capability is provided by
the application and some application may
behave differently.
If you switch to another channel while an
HbbTV application is active (either in red
button icon mode or full UI mode), the
following scenarios can occur.
• The application can continue running.
• The application can be terminated.
• The application can be terminated and
another autostart red button application
can be launched.
HbbTV allows the applications to be
re t r i e ve d b o t h f ro m b roa d ba n d o r
broadcast. The broadcaster may enable
both ways or one of them. If the platfrom
does not have an operational broadband
connection, the platform can still launch
applications transmitted on broadcast.
The autostart red button applications
generally provide links to other applications.
An example of this is shown below. The user
then can switch to other applications by
using the links provided. The applications
should provide a way to terminate
themselves, usually Exit button is used
for this.

Figure b: EPG application, broadcast video is
shown in the upper-right corner of the screen.
HbbTV applications use keys on the remote
control to interact with the user. When an
HbbTV application is launched, the control
of some keys are owned by the application.
