Conditional Access Module
CA Modules are targeted for use in networks by cable operators, that are using Contego scrambling system with pairing from NAGRA. The operators are able to use CA Modules with different types of televisions or set top boxes. There is only one requirement, the end-user device must have DVB-C tuner and compatible CI (common interface) slot.
CA Module already contains application for pairing decoder Contego with smart card. The main advantage of this card is, that customer can choose set top box, which is more suitable for customer than standard set top box from cable operator. CA Module also supports broadcasting in HD, but only in televisions with MPEG-4 tuner.
