Checking EID Values for Encrypted
VOD
Background
An entitlement identifier (EID) value is incremented for every encrypted VOD
session. Set-tops with embedded security have been found to have an EID range that
is out of sync with older versions of the DNCS. These set-tops only accept EID
values between 0x80000000 and 0x8FFFFFFE.
The concern for large systems that have had a high volume of encrypted VOD usage
The concern for large systems that have had a high volume of encrypted VOD usage
for several years is that they may be reaching the upper limit for the EID values that
embedded security set-tops will accept. Once this threshold is reached, no
embedded security set-top on the system will be able to decrypt VOD streams. This
will cause black screens for all encrypted VOD sessions on embedded security set-
tops.
Notes:
Notes:
CableCARD™ hosts have the proper range and have never been affected.
The issue has been addressed in the following software releases:
–
–
DNCS System Release versions 4.3.1, 4.3.2, 4.4.1 SP1, and 5.0;
–
Patch Releases SR 2.8/3.8/4.2 SP3p4 and 4.3.0.14p5EP28.
Cisco® has developed a script that checks the current EID value and warns if it is
getting too close to the upper limit. With site approval, these systems can have the
EID values reset.
The script has no operational impact and takes seconds to run. Resetting the EID
The script has no operational impact and takes seconds to run. Resetting the EID
value will require a stop and start of the camEx process on the DNCS. The restart
takes a few minutes to complete. During this time, no encrypted VOD sessions can
be set up.
