Video Processor Description

9032-OM (V4.1)
Video Processor
The 9032 provides full color processing control (luma gain and lift, chroma
saturation, and color phase) of the output video.
Frame Sync Function
This function provides for frame sync control using either one of two external
reference signals distributed with the card frame, or the input
EXT REF IN (1,2)
video as a frame sync reference.
This function also allows horizontal and/or vertical offset to be added
between the output video and the frame sync reference.
A video delay offset function allows adding or reducing video delay from any
audio delay. This function is useful for correcting lip sync problems when
video and audio paths in the chain experience differing overall delays. A
Reset Framesync function resets the frame sync following any horizontal or
vertical offset changes, clearing any buffered video and re-establishing the
frame sync.
In the event of input video loss of signal, this function provides for disabling
the video, going to a desired color raster, or freezing to the last intact frame
(for analog, last frame free of timing errors).
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.
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.
