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 a: Start bar application
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
applications 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 Setup menu.
