OVERVIEW
The 7812UDXD-AES8-HD and 7812UDXD-HD are Broadcast Quality Up/Down/Cross Converters that
convert between common SD/SMPTE 259M and HD/SMPTE 292M video signals. With its dual scaler and
dual output architecture, the 7812UDXD series simultaneously generates two different HD/SD outputs
with independent phasing. –3G versions add support for common 3G/SMPTE 424M video signals. These
modules support frame synchronization and use FRAME REF inputs on the 7800FR to obtain card
genlock.
With the +3D option, the internal dual scaler architecture is re-configured to receive full resolution Left Eye
+ Right Eye stereoscopic signals and generate a single 1.5Gbs signal with Side-by-Side or Top-Bottom
3D display formatting.
The 7812UDXD series of converters incorporates Mosquito Noise Reduction (MNR) and Block Artifact
Reduction (BAR) in addition to motion adaptive spatial-temporal (3D) noise reduction. The 7812UDXD
series also incorporates new de-interlacing technologies for superior resolution and artifact reduction.
The 7812UDXD series supports dual broadcast quality scaling engines and offers both standard and user
defined ARC modes. AFD (SMPTE 2016) based steering of ARC modes and stamping of AFD codes is
fully supported. Transitions between AFD modes are frame accurate/glitch free. With the +F option,
signals applied to the PGM B IN input can be keyed into image side panels for one of the program
outputs. FILL inputs are frame synchronized so that pre-timing of FILL inputs is not required. With the
{+CF2G} option, static or animated side panels can be stored locally and keyed into image side-panels for
one of the program outputs.
Dual broadcast quality color correction and detail enhancement processors are integrated into the
7812UDXD series. RGB based color legalization is also supported. ITU Rec 709
⇔
601 color space
conversions are performed as needed.
The 7812UDXD series supports 16 channels of embedded audio with audio delay automatically matching
video delay. Additional audio delay is available. Full audio proc is supported including per channel audio
gain, channel swapping and inversion controls. Surround sound (5.1 PCM) to stereo (Lt/Rt or LoRo)
down-mixing is supported.
-AES8 versions of the 7812UDXD series supports 8x discrete AES inputs and outputs in addition to
advanced audio processes like stereo to 5.1 up-mixing (+UMX), Dolby® E/AC-3 Decoding (+DD),
Dolby®E Encoding (+DEE), Dolby®AC-3 Encoding (+AC3E) and IntelliGain® Loudness Management
(+IG). Any two Dolby® encode or decode functions may be integrated into a single card including dual
decoders or dual encoders.
These modules transfer closed caption and time code information from input to output and perform all HD
↔ SD data translations and time code re-calculations. SFP based fiber inputs and outputs are available
with the -F variations.
