9062 Functional Description
1-10 9062 PRODUCT MANUAL 9062-OM (V4.6)
Closed Captioning Processor
This function provides support for closed captioning setup. The function
allows the selection of the ancillary data line number where the ancillary
closed caption data is outputted when the output is HD. When receiving
HD-SDI, both CEA 608 and CEA 708 are supported, with CEA 608 and CEA
708 (containing CEA 608 packets) converted to line 21 closed captioning on
outputs down-converted to SD (on up-convert of SD, only CEA 608 closed
captioning is generated).
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
9062 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 9062. 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.
