Cisco DNCS System Release 2.8.1 3.8.1 4.3.1 User Guide

The camPSM process uses Global Broadcast Authorization Messages (GBAMs) to control various types of
content protection. If the environment variable CC_DATA_FILE  is not set when camPsm starts, the system will
create the copyControlParams.inf file for you with default values.  On the other hand, if the environmental
variable is set to point to a specific file, the configuration values in that file is used.

The system-created copyControlParams.inf file contains the following default configurations:



The DVI/HDMI default configuration always uses HDCP authentication and encryption for the

DVI/HDMI port and blocks the port when authentication fails.



The YPbPr default configuration constrains the image sent to the YPbPr output when the CIT bit is set.



The 1394 port is enabled by default if the connected device supports DTCP; otherwise, the 1394 port

is blocked.



 for encrypted digital

content.

A provision in the software allows for changes to the system-created default configuration. If the default
settings are not adequate for your system's requirements, Contact 

other support configurations. Cisco Services can provide you with instructions on how to enable alternate
configurations that are suitable for your system.

Depending on your system configuration, you may need to change some of the following settings so that they
do not conflict with software that supports content-protection policy settings.

Prior to the release of Service Pack 2 for SR 2.2 and SR 3.2, you may have set up a _DVI SAM service and
package to turn off HDCP on a DVI port. Because the _DVI SAM service cannot be used in conjunction with the
software that supports content-protection policy settings, you are required to delete this service.

After the installation of Service Pack 2 for SR 2.2 and SR 3.2, the HDCP setting will be controlled globally based
on the settings in the copyControlParams.inf file. If subscribers connect a monitor that does not support HDCP
to the DVI port, they will see an HDCP barker.

Because you will no longer be using a package to control the DVI port or the HDCP function, delete the package
that was used for this purpose. However, if the package is used to control other DHCT functions or services, it
should not be deleted.

Note: For instructions on deleting the _DVI SAM Service, see 

To accommodate earlier versions of VOD or xOD that did not support setting the content-protection flag, you
could enable content protection for all VOD or xOD services by adding a file called no_vod_cci to the BFS. If this
file is on the BFS, the DHCT automatically activates content protection on the 1394 output for any VOD or xOD
sessions. If you want the DHCT to protect content based on the settings provided by the VOD or xOD
application, you must remove this file from the BFS. For assistance, see
