Set-top vendor TechniSat has expanded the range of boxes for the Polish pre-paid DTH service Telewizja na kartę (TNK).

TechniSat is offering two new set-top-boxes for TNK, both of which are based on the DIGIT S2-CD model. The DIGIT CD Plus and DIGIT CD Black models include integrated Conex security.

Separately, the TNK service has also added the Discovery Channel to its line-up, taking the total number of channels available to 15, as well as various free-to-air channels.
