1.1 Introduction
The XVP-3901-DPI from Grass Valley, a Belden Brand, is the perfect solution for digital program insertion (DPI)
applications. It embeds SMPTE ST 2010 packets containing SCTE 104 DPI messages based on GPI triggers. It can
also monitor embedded SMPTE ST 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.
The support of AFD (Active Format Description) SMPTE ST 2016, VLI (Video Line Index) RP-186 and WSS (Wide
Screen Signaling) allows the card to adjust its ARC automatically without any external intervention. It will also re-insert
the proper AFD, VLI or WSS on the output along with other HANC and VANC information. With the integration of the
frame sync, incoming feed signals can be synched to house and have the proper ARC when entering the facility. The
XVP-3901-DPI also offers a video proc-amp with full YUV/RGB level controls and RGB gamut correction.
The XVP-3901-DPI provides audio capabilities with processing of up to 32 channels of audio, with automatic delay to
keep lip-sync. It provides shuffling and down-mixing and four AES inputs/outputs for additional flexibility.
The XVP-3901 generates audio/video fingerprints for both outputs (via an iControl option) to detect and measure lip
sync errors in a broadcast facility.
The XVP-3901-DPI allows up to 10 cards to fit in a Densité 3 frame. A bypass relay, on both the XVP-3901-75-3DRP-
R and XVP-3901-110-3DRP-F rears, is available to automatically bypass the card’s processing when the card loses
power or if it is removed from the frame.
The XVP-3901-110-3DRP-F rear has integrated fiber I/O for applications where fiber connectivity is required. A fiber
input/output cartridge is offered as an option. This integrates and makes fiber connectivity easier to install and
configure. Once the cartridge is installed, the inputs or outputs are selectable through the control interface. The input
of the card allows you to select between fiber and copper inputs. The outputs offer 3G/HD path on copper and the SD
path on copper, but the fiber module allows you to select between the SD or 3G/HD outputs to be sent to each fiber
connector.
All card parameters and statuses can be controlled or monitored through iControl.
