UPC-166 Functional Description

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

UPC-166 does not offer Dolby

decoding or encoding, but will pass Dolby

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 UPC-166. 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 ancillary
data line number for the outputted AFD code.
