BBG-1022-FS Functional Description
BBG-1022-FS Functional Description
Figure 1-1 shows a functional block diagram of the BBG-1022-FS. The
BBG-1022-FS frame sync 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. 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.
BBG-1022-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-based (waveform) timecode.
BBG-1022-FS Input/Output Formats
The BBG-1022-FS 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.
•
CVBS IN –
CVBS coaxial analog video input.
•
AES IN –
BNC (AES-3id, 75
Ω
) ports as AES input (number of
ports dependent on model).
•
AN-AUD IN –
Up to four balanced analog audio embed inputs
(number of inputs dependent on model).
•
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.
•
AES OUT –
BNC (AES-3id, 75
Ω
) ports as AES outputs (number of
ports dependent on model).
•
AN-AUD OUT –
Up to four balanced analog audio de-embed outputs
(number of outputs dependent on model).
•
CVBS OUT –
CVBS coaxial analog video usable with SD video
streams.
