4 The DNCS looks up the CableCARD module/Host in its database to determine if
a Host Bound value has been defined for this pair. Based on this information, the
DNCS takes one of the following actions:
If the pair is in the list, and the Host Bound value is Yes, the DNCS allows
binding for this CableCARD/host pair.
If the pair is in the list, and the Host Bound value is No, the DNCS does not
allow binding for this CableCARD module/host pair.
If the CableCARD module is in the list with a different host, the DNCS
continues with step 5.
If the pair is not in the list, the DNCS checks the Maximum Host Change
Count Allowed value (as defined on the CableCARD Server Configuration
screen), and takes one of the following actions:
–
–
If the value is equal to zero (0), the DNCS does not allow binding for this
CableCARD module/host pair.
Note: Setting the Maximum Host Change Count Allowed value to zero
Note: Setting the Maximum Host Change Count Allowed value to zero
disables autobinding.
–
If the value is not equal to zero, the DNCS allows binding for this
CableCARD module/host pair.
5 The DNCS checks the Host Change Count value for the CableCARD module and
compares it to the CableCARD server's Maximum Host Change Count Allowed
value. Based on the values of these two fields, the DNCS takes one of the
following actions:
If the Host Change Count value for the CableCARD module is a smaller
value than the Maximum Host Change Count Allowed value, the DNCS
allows binding for this CableCARD module/host pair, and increments the
Host Change Count by one.
If the Host Change Count value for the CableCARD module is equal to or
larger than the Maximum Host Change Count Allowed value, the DNCS
does not allow binding for this CableCARD module/host pair.
Note: If the Maximum Host Change Count Allowed value is 99, the DNCS
allows the CableCARD module to bind to different hosts an unlimited number of
times.
6 The DNCS sends the podData file containing the binding permissions to the BFS
for those pairs that are allowed to bind (based on the above criteria).
Note: The CableCARD module/host pairs denied binding are not placed in the
Note: The CableCARD module/host pairs denied binding are not placed in the
podData file.
7 The CableCARD module reads the podData file on the BFS.
If the CableCARD module finds its pairing in the podData file, the
CableCARD module authorizes the binding between itself and the host.
If the CableCARD module does not find its pairing in the podData file, the
CableCARD module does not authorize the binding.
