    How is scrambled EIT descrambled

    843851
      In Digital Video and Audio Broadcasting Technology book, it is said PSI and SI table are unscrambled except EIT.

      I wanted to know how is scrambled EIT descrambled ? i.e. who extracts ECM for EIT and gives to CAM or CAM itself extracts the ECM for EIT as EIT pid is fixed ?

      (In case of DVB-CI CAM, for scrambled audio & video, ECM is extracted from PMT and sent to the CAM for descrambling of the audio and video )


      Would be thankful for your replies.......
