9903-UDX-ADDA Functional Description
Figure 1-1 shows a functional block diagram of the 9903-UDX-ADDA. The
9903-UDX-ADDA also includes AES/analog audio support and CVBS/
component video I/O. IA basic signal presence input failover function allows
routing from an alternate SDI source when an input LOS is detected.
The 9903-UDX-ADDA 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.
9903-UDX-ADDA Input/Output Formats
The 9903-UDX-ADDA provides the following inputs and outputs:
•
Inputs:
• 3G/HD/SD SDI IN A and SDI IN B
– two 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/YPbPr IN –
CVBS and component coaxial analog video input
which can receive SD/HD analog video for processing and
up-conversion.
• AES IN –
BNC (AES-3id, 75
Ω
) ports as AES input (number of
ports dependent on rear I/O module used).
•
AN-AUD IN –
Two balanced analog audio embed inputs.
•
Outputs:
•
3G/HD/SD-SDI OUT (1-4)
– four 3G/HD/SD-SDI program video
outputs.
• CVBS/YPbPr OUT –
CVBS and component coaxial analog video
outputs.
•
AES OUT –
BNC (AES-3id, 75
Ω
) ports as AES outputs (number of
ports dependent on rear I/O module used).
• AN-AUD OUT –
Two balanced analog audio de-embed outputs.
