How is scrambled EIT descrambled
Jul 30, 2009 6:31 AM
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.......
