BBG-1002-UDX Functional Description
BBG-1002-UDX Functional Description
Figure 1-1 shows a functional block diagram of the BBG-1002-UDX. The
BBG-1002-UDX up/down/cross converter also optionally 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. Two discrete character burn strings and timecode burn can be
inserted on output video, with each string inserted as static text and/or insert
only upon LOS. 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 uses a built-in web server that allows control/
monitor over computers or smart devices.
The BBG-1002-UDX also provides ARC processing and timecode/
closed-captioning conversion from packet-based timecode formats and
CEA608/708 HD formats to HD ATC, SD_ATC, and SD VITC-based
(waveform) timecode. Closed captioning from CEA708 to HD formats and
line 21 SD closed captioning are available on the processed HD-SD-SDI
outputs.
BBG-1002-UDX Input/Output Formats
The BBG-1002-UDX provides the following inputs and outputs:
•
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.
•
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.
•
RLY BYP B
–3G/HD/SD-SDI which outputs a copy of
SDI OUT 1
under normal conditions, or passive outputs the SDI input on
SDI IN B
as a relay failover if device power is lost.
•
Certain models also provide analog audio inputs/outputs, and
coaxial AES inputs/outputs that allow audio embed/de-embed.
Certain models also provide an CVBS analog video input and
output.
