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 (The
shape and the location of the red button depends on
the application). The red button is displayed for some
and then may disappear. The user then should press
the red button to open the application page. After the
page is displayed the user can go back to the initial
red button icon state by pressing the red button again.
The user 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.
Service with red button application (taken from HbbTv
specification)
If the user swicthes 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 button
0 is used for this.
