possible to have the video component of a service in an SCG with ID “0x0001” while the
audio components of the same service are part of an SCG with ID “0x0002” (another SCG).
If you define a new Scrambling Control Group, the list contains all services, which are
currently not part of other defined Scrambling Control Groups. So the list contains the
services, that you are free to scramble.
If you edit an existing Scrambling Control Group, the list contains all services, that are
currently part of the Scrambling Control Group.
3.19 Provision a new Scrambling Control Group
The following description shows the minimum steps necessary to scramble one or more
service.
•
Click on “Create a new Scrambling Control Group” on the “Scrambling Control
Group List” page. This will automatically choose a name and an appropriate SCG ID
.
•
Enter the access criteria hexadecimal strings for each CAS to be used. At least one
filed of the 4 access criteria fields needs to be filled, to scramble. If you leave a CAS
entry empty, the service(s) will remain free-to-air for users of this CAS.
•
Then check the service or component (or multiple services/components) in the bottom
part of the page. If there are many services available you might need to scroll the page
down in the browser. If you check the box to the left of the service name, all components of the
service will be scrambled. This is the same effect as if you would
check all component check boxes of the service. If you want to scramble single
components only, uncheck the box left to the service name and check the appropriate
boxes to the left of the component.
•
Click on Submit. The scrambler will present the “Scrambling Control Group List”
page, where you will find the new SCG (identified by name and ID).
Please note: If you include multiple services in one Scrambling Control Group, all services
will be scrambled using the same codeword and will be using the same access criteria. If you
want each service to be scrambled with a different codeword (although possibly using the
same access criteria), you have to define a separate SCG for every service.
3.20 Modifying an existing Scrambling Control Group
In the “Scrambling Control Group List” page click on the “active” or date link in the list of
the appropriate Scrambling Control Group. The scrambler will show the “Edit SCG” page.
The bottom part will include a list of services, consisting of services, that are currently being
scrambled (having check marks on at least one component) and services that are currently
free-to-air, but could be scrambled in the future. The latter services having no check marks.
For example: If you want a currently scrambled component to be free-to-air in the future,
uncheck the appropriate component and then click on “Submit” button.
For example: If you want a currently free-to-air service / component to become scrambled in
the future, check the appropriate component and click on the “Submit” button.
For example: If you want the access criteria to change, modify the appropriate hexadecimal
access criteria string and click on the “Submit” button.
