can somebody tell me which part DN needs to update on a subscriber receiver before an ECM? Is the SW inside the smart card? or something else. If this is done thru satellite signal, what types of TS packets are involved for such update?
I believe its the TSOP chip (EEPROM) that resides in your IRD. I don't know what you mean by type of packet, but there are commands that come down in the stream to do things such as update the TSOP code.
