TSBroadcaster 3 Common Download (CDL) is a configuration of TSBroadcaster which is suitable for delivery of OCAP code images and firmware to OpenCable-complient devices. Its features include:
Generation of CVTs Type 2 which are broadcast:
down a DSG Broadcast Tunnel type 5, or,
via the DAC web service interface, or.
via the Cisco BFS
creation of DSM-CC data carousels containing the code image
data carousels are streamed down DSG application tunnels, the in-band FAT channel or placed on a tftp site
TSBroadcaster 3 CDL is installed on a TSPlayer system with one output
includes an easy to configure software multiplexer which handles a variety of input sources; supports PID filtering and remapping
ASI or Gigabit Ethernet outputs
Peer groups for n+1 redundancy
TSBroadcaster can generate multiple transport streams and can connect to one of more TSPlayer systems, each controlling a single transport stream broadcast.
A high degree of fault tolerance can be achieved by using a hot swappable spare of TSBroadcaster 3 CDL. A master/slave pair of TSBroadcasters monitor each other and the slave takes over the role of the master if the master fails.
An ASI switch, available from a number of third party suppliers, can swap TSBroadcaster or TSPlayer outputs from a failed system if required. TSBroadcaster uses the Peer Groups feature to implement n+1 redundancy.
OCAP code images need to be encapsulated in signed PKCS#7 format for the OCAP receiver to authenticate the code download
CVTs delivered via DSG Broadcast Tunnel must also be inserted in a PKCS#7 signed data file
TSBroadcaster 3 CDL provides a "CVT Signers" interface, where the CVT will be sent to an external tool for signature if the CVT needs to be signed
UniSoft offers a CVT signing web service for the OCAP Security File Generator which allows CVTs generated by TSBroadcaster to be sent to OCAP SFG for signature.
