Figure 1-1 shows a functional block diagram of the BBG-1022-2FS. The
BBG-1022-2FS dual-channel frame sync provides two independent signal
paths ( and
Path 1 Path 2
on a single device. The two paths share an input and output SDI crosspoint to
receive and send two discrete SDI inputs and outputs. The BBG-1022-2FS
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 (per path) 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-1022-2FS 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.
The BBG-1022-2FS 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
or
SDI IN A SDI IN B
opposite channel of this pair.
CVBS coaxial analog video input.
• CVBS IN –
BNC (AES-3id, 75Ω) ports as AES input (number of
• AES IN –
ports dependent on model).
Up to four balanced analog audio embed inputs
• AN-AUD IN –
(number of inputs dependent on model).
Outputs:
•
• 3G/HD/SD-SDI OUT (1-4)
outputs. Each output can be independently set as processed output
video or selected input video reclocked.
BNC (AES-3id, 75Ω) ports as AES outputs (number of
• AES OUT –
ports dependent on model).
• AN-AUD OUT –
(number of outputs dependent on model).
CVBS coaxial analog video usable with SD video
• CVBS OUT –
streams.
