    The XVP-3901-DPI is the perfect solution for digital program insertion (DPI) applications. It embeds SMPTE 2010 packets containing SCTE 104 DPI messages based on GPI triggers. It can also monitor embedded SMPTE 2010 packets for specific SCTE 104 split request messages and triggers the appropriate GPO. All DPI events can be monitored and logged though iControl. Using the RS-422 serial port, the XVP-3901-DPI becomes an SCTE 104 injector and it can interface with an automation system to receive and insert a wider range of SCTE 104 messages. The card will return different acknowledge messages to the automation to indicate when the message has been received and when it has been inserted. This allows tracking and logging using the automation's as-run.
