9922-FS Functional Description
Figure 1-1 shows a functional block diagram of the 9922-FS. The 9922-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.
The 9922-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.
9922-FS Input/Output Formats
The 9922-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 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.
•
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 card power is lost.
•
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.
