UDP Mapping pre-encryption checking. Indicates if the APEX is to check if input services are pre-encrypted or clear. Pre-encrypted is determined by examining the input PMT for a CA ECM descriptor (any CA ECM descriptor). If pre-encrypted, setting this flag will cause the APEX to pass through ECM PID for the service. For input services that have a GI CA ECM descriptor, the APEX will also pass through the PIT message (extract and re-insert the PIT). The output PMT for pre-encrypted services will contain a CA ECM descriptor (referencing the ECM PID). When PID Remapping is enabled, pre-encryption for a service is only valid when the input ECM PID is on a different PID than the associated PMT PID. If this flag is set to pre-encryption and the input service is not pre-encrypted, then the setting of this flag has no affect on the output service. Once written, the change to this parameter will take immediate effect and all mappings will be removed. Mappings will not be re-added until apexUdpMapApplyChange is set to 'apply' for all transport streams. In order for the change to persist through subsequent reboots or power cycles, the change must be saved via the apexSaveConfig parameter. @Config(config=yes, reboot=no) @Save(apexSaveConfig, value=2) @File(bcmr.ini, type='ini')
