FUNCTIONAL DESCRIPTION

SD or HD video can be supplied to the PGM A or PGM B input for either path. 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 1920x1080p59.94/50 signals may be supplied to converter inputs. 7814 series
modules support 10 bit 4:2:2, 1920x1080p59.94 single link signals with Level A or Level B formatting per
SMPTE 425M. All modules include integrated frame synchronization capabilities and have an external
genlock input for adjusting output video timing. In addition, 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 is re-inserted into the outgoing video signal with audio delay matching
video path processing delay.
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 per path on –AES8 versions of all modules. AES
outputs can carry different audio than the audio that is being embedded. On –AES8 versions, stereo to
5.1 up mixing is also supported with the +UMX2 option.
Figure 1-1, provides the block diagram for the UDX, the UC, the XC and the HDC variations of the 7814
series products. Figure 1-2 depicts the audio processing block on all -AES8 variations of the 7814 series
products
