The paper's aim is to discuss the strategic character of conditional access
system as an essential element for entry, growth and maintenance in the di
gital TV services provision market. We present the implications for regulat
ion of different conditional access schemas that agents can implement, whic
h potentially include not only competition considerations but also the pres
ervation of general interest, as well as the goal of ensuring a sustainable
competition. This paper Is based on the Spanish experience, one of the fir
st EU countries in regulate digital TV, that it has been a good example of
attempting to regulate technical systems strongly connected to business str
ategies, by means of technical regulation instead of adopting a 'light-hand
ed' approach. Currently, the scenario comprises two different digital satel
lite television platforms, a digital terrestrial television platform and di
fferent cable operators. All of them are competing and offering different p
roducts and services to their real customers. Thus, Spain is the best place
to find what will happen in the future scenario of competence in contents
that will spread across Europe.
