CTE in RTSP/MHA Mode (SDV)
In a typical switched digital headend, the encryption and modulation functions are
separated. The APEX1000 can perform both of these functions.
While operating in RTSP mode, the APEX1000 can encrypt switched content using
Common Tier Encryption. In this mode, all switched QAMs in a service group will have
the same configured RMD and encryption settings.
The following graphic demonstrates how CTE can be applied in an RTSP switched digital
