1 UDC-3901 3G/HD/SD Up, Down & Cross Converter
1.1 Introduction
The Densité Series UDC-3901 from Grass Valley, a Belden Brand is a compact utility grade 3G/HD/SD
up/down/crossconverter with video, audio and metadata processing. It offers up/down/crossconversion, with
simultaneous 3G, HD and SD outputs.
The processor performs all the up/down/ crossconversion, color space and aspect ratio conversion needed to
maintain the chosen output formatting, irrespective of whether the input is 3G (Level A or B), HD 1080i, HD 720p or
SD. To ensure that up/downconverted television is presented in the correct aspect ratio when aired, the UDC-3901
supports AFD (Active Format Description) SMPTE-2016. This provides automatic aspect ratio control using
embedded control commands, and prevents on-air aspect ratio errors such as the postage stamp effect. In addition to
AFD, the UDC also supports VLI (Video Line Index) RP-186 and WSS, which allows the card to adjust its ARC
automatically without any external intervention. The UDC-3901 also processes and converts other ancillary data such
as CC (608/708), timecode, teletext/OP-47 and SCTE-104 ST2010.
An SFP input/output plug-in cartridge option offers a choice of additional input/outputs based from a wide selection of
SFP including CVBS, HDMI, Copper and Fiber SDI. When an SFP cartridge is fitted, the card can select between SFP
additional inputs and BNC/DIN inputs and can output both electrical and optical signals simultaneously.
The UDC-3901 processor’s on-board audio capabilities allows 16 channels of audio, with automatic delay to keep lip
sync, gain control, shuffling and downmixing.
Based on the proven Densité modular framework of over 100 functional cards, the flexible, space-efficient UDC-3901
cards accommodate the transition to multiformat production elements into broadcasting workflows, while protecting
operational methods and investment in installed equipment. With flexibility to configure up to 24 UDC-3901 modules in
the new Densité 3+ FR4 frame with dual SD and 3G/HD simulcast each, the Densité platform scales to new market-
leading density of 6 UDC/RU which means space- and cost-efficient scaling — today and tomorrow.
The Densité UDC-3901 can be controlled by the proven iControl and IControl Solo.

2 Installation
2.1 Installation of Rear Connector Panels
Grass Valley Densité-series cards are each associated with a rear connector panel, which must be installed in the
Densité frame before the card can be inserted.
The UDC-3901 card is designed to fit into Grass Valley’s Densité-3 or Densité 3+ frame. A rear connector panel is
available for each frame type:
•UDC-3901-3+SRP Single-slot-width panel for the Densité 3+ series frame, DIN connectors
•UDC-3901-3DRP Double-slot-width panel for the Densité 3 series frame, BNC connectors
See section 2.6 for details of the signal connections available on each of these panel types.
All cards and rear panels can be installed with the frame power on. The card has connectors which plug into a mid-
frame mother board for distribution of power and for connection to the controller card, and a second connector which
plugs directly into the rear connector panel for input and output.
The rear connector panel must be installed with the card out of the frame.
•To remove an existing card from the slot, tilt up the swivel handle on the front of the card to lever the connectors
apart, then use the handle to pull the card straight out of the slot.
Figure 2.1 Densité-3 frame – rear panel installation
To install the connector panel:
1. If a card is installed in the slot whose rear panel is being changed, remove it as described above.
2. Remove the existing panel (either blank or belonging to an existing card that is being changed) by releasing the
captive screw at the bottom.
3. Position the new panel and secure it in place with the captive screw at the bottom.

2.2 Card Installation
Once a matching rear connector panel has been installed, install the UDC-3901 card as follows:
1. Open the front panel of the frame.
2. Slide the UDC-3901 card into the slot and push gently on the handle to seat the connectors.
The card should be inserted into the right-most slot associated with the double-slot or triple-slot rear panel.
Inserting the card into the wrong slot will not damage the card, and will be flagged by the on-card status LED
flashing red to indicate that there is no connection to the rear panel.
3. Close the front panel of the frame.
2.3 Installation of the Optical Interface (option)
Refer to ANNEX 3 – Installing the Optical Interface on page 94.
2.4 ABUS Connection to Companion Audio Cards
When the UDC-3901 is used in conjunction with one or
two companion audio cards (Grass Valley’s AAP, DAP
or UAP series), the ABUS flat cable must be installed
between the ABUS connector of the UDC-3901 and the
connectors on the audio cards. The ABUS flat cable is
supplied with the audio card.
Note that audio cards from the Densité 2RU series will
require 3RU extenders for both the card and the
associated rear panel in order to fit into the Densité
3RU frame with the UDC-3901.
Note: If only one audio card is used, you must use the
two end connectors on the ABUS cable, and leave the
center connector unplugged

2.5 Rear Panels and Connectors
2.5.1 Summary of rear panel connections
The chart summarizes the connections featured on each of the available UDC-3901 rear connector panels.
Figure 2.3 UDC-3901 Rear Panels
2.5.2 Details of rear panel connections
REF IN – Studio reference input
For external synchronization, connect a black studio reference signal to the BNC labeled REF IN.
The reference input must conform to SMPTE 170M/SMPTE 318M/ITU 624-4/BUT 470-6 for standard definition
signals and SMPTE 274M / SMPTE 296M for high definition signals and is used to phase the HD/SD SDI outputs to
the studio. A reference mismatch may occur if there is a difference between the input video format’s frame rate and
the reference format’s frame rate. When a mismatch occurs, the output will freeze to the reference frame rate and
produce an input error and the card-edge Status LED will turn red to indicate the mismatch.
Note that in the case of HD signals of the same frame rate, any reference signal may be used to genlock any output
signal, regardless of scan type (progressive or interlaced). When a 720p/tri-level sync reference signal is used with an
interlaced output, the output is synchronized but there may be a delay of one field depending on when the
synchronization started.
