Figure 1-1 shows a functional block diagram of the 9902-DC-4K. The
9902-DC-4K includes input routing to accommodate up to four 3G/HD-SDI
inputs for converting 4K quadrant-division and 2SI (two-sample interleave)
content into 3G-SDI. The 9902-DC-4K precisely combines four
quadrant-divided or 2SI individual SDI feeds into a combined SDI image
directly suitable for broadcast production usage or monitoring purposes.
Frame sync is optionally available which equips each path with independent
frame sync. The output is available as a 2x DA 3G/HD-SDI output or HDMI/
DVI.
The 9902-DC-4K provides the following inputs and outputs:
Inputs:
•
• SDI IN A thru SDI IN D
quadrant-division or 2SI inputs)
Outputs:
•
• 3G/HD-SDI OUT
outputs
• HDMI/DVI OUT
audio embedding (suitable for direct connection to monitor panels)
Note: Although the inputs will receive SMPTE 424M, 292M, or 259M inputs,
quadrant-combined 4K content is realized only using 3G (SMPTE 424M)
inputs for all inputs.
