Introduction
9071 Functional Description
9071 Functional Description
Figure 1-1 shows a functional block diagram of the 9071. The AFD inserter
function provides for assignment and insertion of AFD codes into the SDI
output video. Using this function, AFD codes in accordance with the standard
4-bit AFD code designations can be applied to the output video.
This function checks for any existing AFD code within the received video
input. If a code is present, the code is displayed. When used in conjunction
with a separate downstream card capable of providing AFD-directed scaling,
the image can in turn be scaled in accordance with the AFD coding embedded
by this card.
The function also allows the selection/changing of the AFD code ancillary
data line number for the outputted AFD code.
9071 Input/Output Formats
The 9071 provides the following inputs and outputs:
• Inputs:
• HD/SD SDI IN – dual-rate HD/SD-SDI input
• Outputs:
• SDI OUT – four HD/SD-SDI buffered video outputs
• RCK OUT – four HD/SD-SDI reclocked buffered video outputs
