The ECD is also implemented in all the CAMs. STBs with ECD usually have some kind of descrambler like Viaccess or Irdeto implemented. In that case you don't need a CAM, only a smartcard, for decryption. Most/all of those descrambling systems use ECD, only the algorithm for the encryption of the keys is different and gives the system its name.
