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 (currently various
channels on Astra broadcast HbbTV applications).
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 retrieved both from
broadband or 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
on the left bottom, can be terminated by pressing 0.
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. For example, numeric channel selection may
not work on a teletext application where the numbers
indicate teletext pages.
HbbTV requires AV streaming capability for the platform.
There are numerous applications providing VOD (video
on demand) and catch-up TV services. The user can
use play, pause, stop, forward, and rewind keys on the
remote control to interact with the AV content.
Note: You can enable or disable this feature from the More
menu in System>Settings menu.
