The two large cable operators (joint market share 70%) in the Netherlands are blocking the HbbTV signals from broadcasters on their networks for no stated reason. It is speculated that the reason is to prevent competition with their own interactive services. The Dutch parliament want to have this block ceased now. This would enable many smartTVs with CI+ modules to receive enhanced programming (interactivity). People using cable-boxes (and older TVs without HbbTV) would still not be able to access such services.
Note: there could be some interference between HbbTV applications and interactive applications from the operator on the CI+ module. I.e. at minimum some technical testing work may have to be conducted on already deployed products.
Nevertheless, there seems to be significant room for a more constructive solution.
