Chapter 13 Encryption and Scrambling
When the 'Advanced' radio button is clicked for the Internal PowerKEY ECMG, the
following table is displayed.
If the encrypted content is to be streamed for the non-Cable Card STB's running the
Rovi Application, the 'Hint Bit Stop Delay' parameter must be set as -400 msecs and
the 'Overrule Hint Bit Stop Delay' flag must be set to 'True' for the STB's to
descramble the content without any issues.
ECMG Descriptor Rules
CA descriptors are data structures used to carry CA specific information for services
or elementary streams. The RFGW-1 is able to update PMTs with CA descriptors
according to the user configurable CA descriptor rules. The SCS configurator allows
configuring CA descriptor rules and applying these rules to descriptors.
Note: When the RFGW-1 scrambles a service or components within a service, CA
descriptors in the PMT are sorted using the values of the ECM PIDs to which the CA
descriptors apply. CA descriptors with the lowest value appear first. When a
scrambled service is passed from input to output of the RFGW-1, the CA descriptor
order is not changed.
Adding a Descriptor Rule
