TS Out Decrypt
TSO or Transport Stream Out Decrypt determines how BISS encrypted transport streams
are processed. This configuration provides end users flexibility on how the RD is used. The
TS Out Decrypt configuration determines if the ASI output should mirror the selected input
(OFF), thus preserving any encrypted streams or if it should be decrypted / free to air (ON).
TS Out Decrypt should be set to OFF, the default configuration, if the IRD is to be used in a
confidence decode / turn around application. A confidence decode / turn around application
can involve the IRD being used a turn around device (IP to ASI or RF to ASI) where the user
wants to preserve encryption on the ASI output, but also wants to decode one of the
incoming programs. This configuration also allows the RD to ingest encrypted MPTS streams
that may be over the TSO limit. A sample diagram of how the transport stream is passed to
the ASI output through the system is shown below.
If the user wants to use the IRD as a decoder and decrypter, the TS Out Decrypt
configuration should be set to ON. All programs will be decrypted with the user supplied
BISS key and transported to the ASI output. This application is useful for users that want to
redistribute the stream to other non-BISS devices, such as transport stream analyzers or
third party decoders. Please note that when in this mode, total transport stream throughput
must not exceed the rate stated in the Technical Specifications found in Appendix B.
