this causes your problem, contact your internet
service provider. A firewall might be the reason of a
connectivity and discovery problem while using the TV
in DLNA mode or while browsing via DLNA.
Invalid Domain
Ensure that you have already logged on to your PC
with an authorized username/password and also
ensure that your domain is active, prior to sharing
any files in your DLNA server program on your PC. If
the domain is invalid, this might cause problems while
browsing files in DLNA mode.
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 button 0 is used for this.
Figure a: ARD start bar application
Figure b: ARD 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
teletect 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 Other Settings menu in Settings menu.
