The FS1 does not insert an AFD code into the output. If the video input has an AFD
code and the FS1 is not Up/Down/Cross converting it, the input AFD code will be
passed through to the output.
If the FS1 is not upconverting or downconverting the input video, the input AFD
code is passed through. If there is no AFD code on the input video, a “Full Frame”
(8) code is inserted. If the FS1 is upconverting, the appropriate AFD code will be
chosen based on the upconvert mode.
The FS1 always inserts a “Box > 16:9 (center)” AFD code (4), which indicates that
the HD image has an aspect ratio greater than 16:9 as a vertically centered
letterbox within the 16:9 frame.
The FS1 always inserts a “Full Frame” AFD code (8), which indicates that the HD
image is full frame, with an aspect ratio that is 16:9.
The FS1 always inserts a “4:3 (center)” AFD code (9), which indicates that the HD
image has a 4:3 aspect ratio as a horizontally center pillarbox image within the
16:9 frame.
The FS1 always inserts a “16:9 (with complete 16:9 image protected)” AFD code
(10), which indicates that the HD image is full frame, with a 16:9 aspect ratio and
all image areas are protected.
The FS1 always inserts a “14:9 (center)” AFD code (11), which indicates that the
HD image has a 14:9 aspect ratio as a horizontally centered pillarbox within the
16:9 frame.
The FS1 always inserts a “4:3 (with alternate 14:9 center)” AFD code (13), which
indicates that the HD image has a 4:3 aspect ratio and with an alternative 14:9
centered pillarbox image within the 16:9 frame.
The FS1 always inserts a “16:9 (with alternative 14:9 center” AFD
code (14), which indicates that the HD image has a 16:9 aspect ratio with an
alternative 14:9 center within the 16:9 frame.
The FS1 always inserts a “16:9 (with alternative 4:3 center)” AFD code (15), which indicates
that the HD image has a 16:9 aspect ratio with an alternative
4:3 center within the 16:9 frame.
