Overview of VPME
The PME Video On Demand system integrates the encrypted VOD content within an Arris digital cable headend. A VOD system provides the clear content while the Cisco cBR-8 and CEM are added to provide encryption. The details on the usage of the CEM are described in this chapter. Every MSO site should have the CEM application, which is the single entity connecting to the Arris Encryption Renewal System (ERS). All the Cisco cBR-8s on this MSO site should connect to this CEM.
Prerequisites for VPME
To enable VPME encryption, the connection to the CEM should be configured. VPME is a licensed feature and requires appropriate license on the chassis. The following connection should be configured:
The video traffic flow on the Ten Gigabit interface.
Table-based video sessions.
QAM PHY parameters for the physical QAM channel.
Restrictions for VPME
You can configure the line card in only one mode as the table-based session configuration and dynamic GQI-based sessions are mutually exclusive. Hence, PME and PowerKey encryption are also mutually exclusive modes at the line card level. For more details, see Configuring the Encryption Type on the Line Card section.
