9902-UDX-FS Functional Description
Figure 1-1 shows a functional block diagram of the 9902-UDX-FS. The
9902-UDX-FS dual-channel card provides same-card dual independent signal
paths (
Path 1
and
Path 2
) of UDX conversion/frame sync (Path 1), and frame
sync (Path 2). Both paths provide audio embedding and de-embedding on a
single card (with channel swapping available between the two paths). The two
paths share an input and output SDI crosspoint to receive and send two
discrete SDI inputs and outputs. The 9902-UDX-FS also includes AES/
analog audio support and CVBS video I/O. In addition to a basic signal
presence input failover function, a Quality Check option allows failover to
alternate inputs based on user-configurable subjective criteria such as black or
frozen frame. A moving-box insertion can be enabled to serve as a dynamic
raster confidence check even in cases where the input video image is static or
lost.
The 9902-UDX-FS also provides timecode/closed-captioning conversion
from packet-based timecode formats and CEA608/708 HD formats to HD
ATC, SD_ATC, and SD VITC waveform-based timecode.
9902-UDX-FS Input/Output Formats
The 9902-UDX-FS provides the following inputs and outputs (which can be
independently used for Path 1 and/or Path 2:
•
Inputs:
•
3G/HD/SD SDI IN A thru SDI IN D
– four 3G/HD/SD-SDI inputs.
SDI IN A
or
SDI IN B
can be set to failover to
A
or
B
in absence of
opposite channel of this pair.
•
CVBS IN –
CVBS coaxial analog video input.
•
AES IN –
BNC (AES-3id, 75
Ω
) ports as AES input (number of
ports dependent on rear I/O module used).
•
AN-AUD IN –
Four balanced analog audio embed inputs.
•
Outputs:
•
3G/HD/SD-SDI OUT (1-4)
– four 3G/HD/SD-SDI buffered video
outputs. Each output can be independently set as processed output
video or selected input video reclocked.
•
AES OUT –
BNC (AES-3id, 75
Ω
) ports as AES outputs (number of
ports dependent on rear I/O module used).
•
AN-AUD OUT –
Four balanced analog audio de-embed outputs.
•
CVBS OUT –
CVBS coaxial analog video usable with SD video
streams.
Note:
Input select also allows internal connection from one processing path output
to the opposite processing path input. This allows “serial” processing
connections without requiring external jumpering on the card rear I/O module.
