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.
