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.
