Introduction
BBG-1002-UDX-FS Functional Description
BBG-1002-UDX-FS Functional Description
Figure 1-1 shows a functional block diagram of the BBG-1002-UDX-FS. The
BBG-1002-UDX-FS dual-channel unit provides two independent signal paths
(
Path 1
and
Path 2
) of UDX conversion, frame sync, and audio embedding and
de-embedding on a single unit. The two paths share an input and output SDI
crosspoint to receive and send two discrete SDI inputs and outputs. The
BBG-1002-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 BBG-1002-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.
BBG-1002-UDX-FS Input/Output Formats
The BBG-1002-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 unit rear panel.
