Overview
The UDC-8225A is a universal cross-converter designed for broadcast use. It can provide SD to
HD up-conversion, HD to SD down-conversion, as well as HD to HD cross-conversion.
The UDC-8225A supports all popular standard definition and high definition video formats, with
or without four groups (16 channels) of embedded 48kHz synchronous audio, including 480i,
576i, 720p, and 1080i. The format of incoming video is automatically detected, simplifying
system setup.
A licensed software option for the UDC-8225A includes an additional input which is used to
insert additional content in the blank areas of the converted output (Letter Box and Pillar Box).
This is accomplished through implementing a Box Mask, which matches the active area on the
converted output, and enabling the insertion of the input on a signal that has been converted by
our aspect ratio converter.
The UDC-8225A converts the incoming SDI video, on the main SDI In, to any supported video
format. Using advanced video de-interlacing algorithms, dynamic edge detection, adaptive noise
reduction circuitry and full 10-bit processing, format conversion is performed with the highest
possible picture quality. As part of the format conversion process, a flexible aspect ratio converter
allows the video to be re-sized to a number of standard aspect ratios.
The UDC-8225A incorporates a video frame synchronizer, allowing the output video to be timed
to an external video reference.
Any openGear DFR-8300 series frame supports a distributed frame reference, allowing incoming
reference sync signals to feed timing information to all modules in a frame. Thus, a single
composite or tri-level sync signal can be used for multiple cross-converters. Alternatively, each
card accepts an additional reference signal providing additional system timing flexibility.
To make configuration easier, the cross-converter offers a unique Heads-Up Display (HUD) on a
separate composite monitoring output. When activated, card status and parameters can be viewed
and adjusted using the card-mounted finger joystick and an easy to use menu system. Alternately,
you can configure the UDC-8225A using the DashBoard Control System which also enables you
to install licensed software features such as the Wings Input option.
The UDC-8225A is fully compliant with all openGear technical specifications and supports
remote monitoring via the DashBoard Control System.
