1-6
Figure 1-1 shows a functional block diagram of the 9922-2FS. The 9922-2FS
dual-channel frame sync provides two independent signal paths (
) of frame sync / audio embedding and de-embedding on a single card.
Path 2
The two paths share an input and output SDI crosspoint to receive and send
two discrete SDI inputs and outputs. The 9922-2FS 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 9922-2FS also provides timecode/closed-captioning conversion from
packet-based timecode formats and CEA608/708 HD formats to HD ATC,
SD_ATC, and SD VITC waveform-based timecode.
The 9922-2FS 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
SDI IN A
opposite channel of this pair.
• CVBS IN –
• AES IN –
ports dependent on rear I/O module used).
• AN-AUD IN –
Outputs:
•
• 3G/HD/SD-SDI OUT (1-4)
outputs. Each output can be independently set as processed output
video or selected input video reclocked.
• AES OUT –
ports dependent on rear I/O module used).
• AN-AUD OUT –
• CVBS OUT –
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 card rear I/O module.
