Dolby

Metadata Extractor/Re-inserter
This function extracts and preserves Dolby
®
metadata from the input SDI, and
in turn allows the metadata to be re-inserted in the output SDI. This allows 
scaling and/or format conversions without losing Dolby
®
metadata. (The
9066 does not offer Dolby
®
decoding or encoding, but will pass Dolby
®
E
and/or Dolby
®
Digital™ encoded signals and metadata intact.) The extracted
metadata is buffered and then output on a user-selectable line number on the 
SDI output, and on the 
DOLBY META
RS485 connector (on cards equipped
with appropriate Rear I/O Module).
AFD Processor
This function provides aspect ratio controls and assignment of AFD codes to 
the SDI output video.
Using this function, aspect ratios in accordance with the standard 4-bit AFD 
codes can be applied to the output video. Additionally, custom aspect ratios 
can be independently defined for any of the AFD codes. 
Separate, independent AFD controls are provided for both 16:9 coded and 4:3 
coded frames.
This function also provides AFD-controlled ARC by checking for any 
existing AFD code within the received video input. If a code is present, the 
code is displayed. With the Scaler function 
Aspect Ratio Conversion
set to
Follow AFD Settings
, the H and V settings corresponding to the received code
are applied to the video by the 9066. The default, standard aspect ratio 
described by the AFD code can be applied, or custom horizontal/vertical 
scaling can be applied for a given code.
The function also allows the selection/changing of the AFD code and 
ancillary data line number for the outputted AFD code.
