Information About Pre-encrypted Broadcast Video

The Cisco cBR-8 line card supports broadcast video. It also provides support to the WAN ports for receiving Multi program Transport Streams (MPTS). The Cisco cBR passes the MPTS streams in its entirety to multiple RPDs in the network to provide an output on their RF ports.

The content is multiplexed and encrypted during upstream traffic and reaches Cisco cBR-8 router as pre-encrypted in a constant bit-rate MPTS with all the PSI present. The Cisco cBR routers perform the following:

  • De-jittering

  • Clock recovery

  • PCR re-stamping

  • Regenerates PAT with correct TSID

Typically, multi-system operators (MSO) have between 64 and 75 carriers of Broadcast video content in their system. In the RPHY environment, the Cisco cBR routers convert the Broadcast carriers into DEPI multicast streams and send them to an unlimited number of RPDs over the Converged Interconnect Network.

Multicast Table-based Sessions

Similar to table-based unicast session configuration, sessions can be configured as individual sessions under each QAM carrier that is assigned to a table-based LED. To configure multicast video session, you must configure a port-channel interface.

A multicast session can be configured with a single input multicast input source or multiple input sources for backup purpose. For multiple backup sources, a label is required to be associated with the session configuration. Same label can be applied to multiple sessions on different QAM channel. These sessions are considered as cloned sessions.

For session cloning on multiple QAMs within the same line card, only one copy of the traffic is forwarded to the line card. The line card replicates the input packets and forwards them to multiple QAMs. Each cloned copy of a remapped session will have the same or different output program number.

MPTS Pass-through Session

The Cisco cBR-8 router supports multicast MPTS pass-session type. For a pass-through session:

  • The PMT and other program data are not changed.

  • PID remapping is not performed.

  • Input NULL packets are dropped.

  • Oversubscription results in random TP dropping, and all ghost PIDs are preserved in the output.

How to Configure Pre-encrypted Broadcast Video Sessions

This section contains the following:

Configure a Port-Channel Interface

The following example shows how to configure a port-channel interface.

Configuring the Service Distribution Groups and Binding

The Service Distribution Group (SDG) defines the physical slot/bay/port to be used in a video service. After you configure an SDG, you can bind a VCG to an SDG. The binding connects the carriers defined in the VCG to the physical port listed in the SDG. After binding, a path from the Virtual Edge Input (VEI) is mapped to the RF channels.

The following example shows how to configure the SDGs and binding:

configure terminal 
cable video
service-distribution-group sdg99 id 99
    rpd downstream-cable 9/0/31

  virtual-carrier-group vcg99 id 99
