9033-OM (V4.0) 9033 PRODUCT MANUAL 1-7
Introduction
9033 Functional Description
Video Processor Description
Video Processor
The 9033 provides full color processing control (luma gain and lift, chroma
saturation, and color phase) of the output video.
AFD Inserter
This function provides for assignment and insertion of AFD codes into the
SDI output video. Using this function, AFD codes in accordance with the
standard 4-bit AFD code designations can be applied to the output video.
When used in conjunction with a separate downstream card capable of
providing AFD-directed scaling, the image can in turn be scaled in
accordance with the AFD coding embedded by this card.
The function also allows the selection/changing of the AFD code and
ancillary data line number for the outputted AFD code.
Dolby ® Metadata Extractor/Re-inserter (9033-DEC only)
This function allows Dolby ® metadata from the Dolby decoder, to be inserted
in the output SDI. The extracted metadata is buffered and then output on a
user-selectable line number on the SDI output, and on an RS-485 port on
cards equipped with an appropriate Rear I/O Module.
Timecode Processor
(See Figure 1-2.) This function provides for extraction of timecode data from
the input video (for SD formats), and in turn re-insertion of timecode data into
the output SDI. Timecode insertion (depending on raster format) can select
and prioritize among SDI VITC, SDI ATC VITC, and SDI ATC LTC
timecode sources.
The function provides conversion between various timecode formats and
provides independent insertion and line number controls for each SDI
timecode output format.
Option +LTC allows bidirectional transfer and conversion
between VBI formats over SDI and audio LTC, as well as RS-485 LTC.
Audio LTC can be received or sent over a selected balanced analog audio
input, or as digital audio over a selected AES input.
