3.7.26.3 BISS and Stored Configurations
Both an xml and stored configuration will contain an entry for a BISS key, if a key
had been set for the service on the unit that the configuration was saved from. To
comply with the specification that requires the value of keys that are not available on
external interfaces and cannot be retrieved, this uses the name of the table location
(BISS Key n).
Loading an xml or stored configuration with BISS enabled will successfully configure
the unit, resulting in a Transport Stream output and service configured, with BISS
enabled using the same BISS Key n setting as for the original configuration. The
contents of the BISS key table are NOT transferred, so unless the same key has
already been entered the key will either be not set or a previously entered different
key might be applied. To ensure the correct key is set the user can edit the key
stored in the table as described above.
Loading an xml that contains a BISS key entry onto a unit that has never had BISS
enabled will not enter any keys.
******NOTSET*****
will still be displayed on the user
interface and the output WILL NOT be encrypted. A key needs to be manually
entered.
Once a BISS key has been set for a service, switching BISS off does not affect the
storage of the key. The key is maintained and used when BISS is re-enabled. If a
different key is required it needs to be manually updated, or a different key from the
table selected. The entered keys are maintained over a power cycle.
Note: Deleting the unit configuration does not delete the contents of the BISS key
table.
3.7.27 How to Set Up Audio Pass-thru
When configuring the audio module to pass audio without encoding, it is necessary
to set the audio encode coding standard to Pass-thru before selecting the audio
input format to the pre-compressed format to be passed.
Note: If an attempt is made to select a pre-compressed input format while the
module is configured to encode audio, an error message referring to no
more licenses… will be displayed, and the configuration cannot be applied.
