Introduction
BBG-1002-2UDX Functional Description
BBG-1002-2UDX Functional Description
Figure 1-1 shows a functional block diagram of the BBG-1002-2UDX. The
BBG-1002-2UDX 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-1002-2UDX 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-1002-2UDX 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-1002-2UDX Input/Output Formats
The BBG-1002-2UDX 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.
