ba196bb15f748a09ab0343a91f7ae765 | 102 825-9 | 7.1.1 General | This clause specifies how CPCM is adapted to work over the DVB Common Interface (DVB-CI) (see EN 50221 [4]). This is achieved by the definition of a particular copy protection resource, as defined in the DVB Extensions to the Common Interface Specification (see TS 101 699 [5]) that corresponds to a CPCM Instance. The C... |
ba196bb15f748a09ab0343a91f7ae765 | 102 825-9 | 7.1.2 Additional Requirements for CPCM support | In order to support CPCM, the interrupt mode implementation, defined as optional in the DVB-CI specifications ([5]), becomes mandatory. The DVB CI module shall announce the interrupt mode support in the Card Information Structure (CIS). A host shall switch to interrupt mode as soon as the DVB CI module triggers interru... |
ba196bb15f748a09ab0343a91f7ae765 | 102 825-9 | 7.1.3 CPCM System Adaptation to DVB-CI | The CPCM Instances in both the Module and the Host shall be implemented as Copy Protection resources as defined in TS 101 699 [5]. Copy Protection resources are identified by the CopyProtectionID field, whereby the IEEE company_id (see TS 102 825-5 [10]) is used to identify the copy protection system. Copy Protection r... |
ba196bb15f748a09ab0343a91f7ae765 | 102 825-9 | 7.1.4.1 General | A key application for CPCM over DVB-CI is the provision of a standardised method for the protection of the transport stream interface between the CI module and the host.

ba196bb15f748a09ab0343a91f7ae765 | 102 825-9 | 7.1.4.3 CPCM LSA | The CPCM Security Toolbox specification defines the CPCM LSA (Local Scrambling Algorithm) as having two possible chaining modes and two possible IV preparation modes, thus resulting in four possible combinations of these scrambling options. Since it is always the CPCM Content Source that decides which of these four com... |

39654675b83791df5e95eafe093f127f | 102 822-5-2 | 5 Secure binding by content scrambling | This method is applicable to scrambled content. The security of this binding method depends on the use of content scrambling keys that are sufficiently unique for each binding. This method tests for the association of the content keys with the RMPI and then tests the content with the content keys. The content license i... |
