FUNCTIONAL DESCRIPTION
SD or HD video can be supplied to the PGM A or PGM B input. Either PGM A or PGM B may be selected
for video processing and up/down/cross conversion. With the –3G versions of these modules, single link
or dual link 1920x1080p59.94/50 signals may be supplied to converter inputs. 7812UDXD series modules
support 10 bit 4:2:2, 1920x1080p59.94 single link signals with Level A or Level B formatting per SMPTE
425M. When configured to accept dual link SMPTE 372M signals, both PGM A and PGM B inputs are
used. Nominally, PGM A is used to accept LINK A and PGM B is used to accept LINK B. Internally, 7812
modules have the ability to swap the source for LINK A and LINK B if required. When set to output dual
link SMPTE 372M signals, PGM OUT 1/2 are assigned for LINK A and PGM OUT 3 is assigned for LINK
B. All modules include integrated frame synchronization capabilities, the cards support FRAME
REFERENCE inputs as supported on the 7700FR-G and the 7800FR.
The video signal selected for processing (PGM A or PGM B) is routed through a number of advanced
processing stages including frame synchronization, audio/Dolby metadata extraction, noise reduction, de-
interlacing, aspect ratio conversion, up/down/cross conversion, video proc adjustment and detail
enhancement. De-embedded audio and Dolby metadata is re-inserted into the outgoing video signal with
audio delay matching video path processing delay.
One of the final stages of processing includes keying of the FILL input or embedded compact flash
content onto the output image (+F or +CF2G option only). With the +F option, the PGM B input is used to
supply a FILL input signal that can be keyed into unused portions of the output image raster (i.e. side
panels typically generated when converting from 4:3 to 16:9). When operating in this mode, the FILL input
signal is automatically frame synchronized so that pre-timing of FILL input signals
is not
required. With
the +CF2G option, static or animated side panels may be stored in the on-board compact flash to be
keyed into image side panels. Content for the compact flash is generated using Evertz’ Overture Media
Design and may be loaded to 7812UDXD series modules using Overture Media Manager. Files may also
be sent directly to the modules on-board compact flash using standard FTP techniques. As another
alternative, the compact flash may also be physically extracted from the card, loaded remotely and then
replaced again.
Note: FILL input signals are not up/down/cross converted so it must match the output
resolution configured for the module
.
Note: When ordering the +CF2G option, the functionality delivered by the +F option is
automatically included as well.
Within the audio processing block, audio delay is matched to track video delay. In addition, channel
swapping, gain and inversion processing is available. Down-mixed audio is also generated in this block.
8x AES inputs and 8x AES outputs are supported on –AES8 versions of all modules. AES outputs carry
the same audio that is being embedded. On –AES8 versions, stereo to 5.1 up-mixing is also supported
with the +UMX option.
Figure 2-1 provides the block diagram for the 7812UDXD series products. Figure 2-2 depicts the audio
processing block on all -AES8 variations of the 7812UDXD series products.
