Operation
42

Seven input parameters (Input > AFD/VI/WSS De-embedder) on SFS6803
+
modules
indicate the presence of AFD, WSS, and VI data when you determine the lines where
this data is likely to appear, if present.

The single processing parameter ( Out Aspect Ratio , which appears at Processing >
Video > AFD/VI/WSS) determines the options for the AFD Select and VI Select
parameters.

Fifteen output parameters (Output > AFD/VI/WSS Embedder) determine the line to
embed AFD, WWS, and/or VI codes on, the code(s) to be embedded, and what
happens when a code disappears from the input.
Cross-Functional Parameter Changes
When you configure certain parameters, you force a change in other associated
parameters. The various conditions that affect parameter availability or settings are
described in the following sections:

Out Aspect Ratio on page 42

ADS Clean Parameter on page 43

Frame Sync Bypass Parameter on page 43

Channel Word Length on page 44

Parameter Availability Based on Operating Mode on page 44
Out Aspect
Ratio
When the Out Aspect Ratio parameter (Processing > Video > AFD/VI/WSS) is set to 4:3,
the AFD Select and VI Select parameters (Output > AFD/VI/WSS Embedder) have the
following options:

16:9 top

14:9 top

>16:9 in 4:3

4:3 full

16:9 l

14:9 l

4:3 a 14:9

16:9 l a 14:9

16:9 l a 4:3
When the Out Aspect Ratio parameter (Processing > Video > AFD/VI/WSS) is set to 16:9,
the AFD Select and VI Select parameters (Output > AFD/VI/WSS Embedder) have the
following options:

16:9 full

14:9 p

>16:9 in 16:9

4:3 p

16:9 prtctd

4:3 p a 14:9

16:9 a 14:9

16:9 a 4:3
