9067 Functional Description
1-10 9067 PRODUCT MANUAL 9067-OM (V4.4)
Closed Captioning Processor
This function provides support for closed captioning setup. The function also
allows the selection of the ancillary data line number where the ancillary
closed caption data is outputted when the output is HD.
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
9067 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.
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 9067. 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.
Audio Processor Description
The audio processor operates as an internal audio router. The router function
chooses from the following inputs:
• 16 channels of embedded audio from the SDI video input
• Four independent internal tone generators (described below)
• Internal Down Mix and Mono Mixer outputs (described below)
• Digital silence (mute) setting
