The Dutch pilots

  • Digital Rights Management

For the first phase of the DRM pilot we created a special filter-application inside the existing HbbTV  Catch-up platform of NPO. The test panel received about 90 items in 5 different genres to watch.


They held  a virtual budget of 9 Euros and each items was offered in HD (3 Mbps HLS) and SD (1 Mbps HLS) quality. HD items where price differentiated , depending on in which  (sub) test group they were marked. This was mainly to investigate the willingness to pay for HD quality per genre and to investigate the technical possibilities to offer the same content in different qualities.


For the second phase of the pilot is the test panel has been asked to keep a diary of their viewing habits. The first few days on their current offer of on demand television (public, commercial, Netflix etc). After that they all received free subscription on NLZiet (a paid service from public broadcaster NPO and commercial broadcasters RTL and SBS for 9 Euros a month) and they were asked to fill in a diary of their viewing habits. At the end of the month they did this one more time for a few days. KUL analysed the diaries. Due to too low response we could not finish this phase successfully. Instead of that KUL did some extra literature study on the subject ‘willingness to pay’ and different subscription models.

  • In house Recommendations for HbbTV

In the first phase a test panel of 40 participants got different recommendations presented on different timeslots per day. They had to rate these recommendations on relevance for them at that particular time of the day. For the second round of recommendations we improved the algorithm of the recommendations, based on an analysis of the first period. Also we offered the recommendation in three different UI formats: long form content, short form content and content for children. The test panel again rated the recommendations on relevance and we asked them to record their viewing habits in a diary.



  • ‘HbbTV as a central interface for second screen competition’

We did several tests with different TV-shows within a test panel of around 60 users with shows like ‘de Rijdende Rechter’ and ‘Een-tegen-100’.


Users could play along the quiz with their second screen application on a mobile device or tablet and their results (scores and ranking) were presented on the TV-screen, through a transparent overlay on the program. We also did an international test with the Eurovision Song Contest. A few households in Spain and the Netherlands played along and could see their group results presented on the TV-screen.


In 2016 we executed some more quiz tests and made the application available for a wider range of devices (Samsung, Sony, LG and Philips).

 The application is now being developed as a commercial product and put into the market as ‘see2gather’.
