Input Video Controls
Allows manual or failover selection of SDI program
video inputs and displays status and raster format of
received SDI video.
• Input Video Source/Status Selects the input video source to be applied to the Path 1 and
Path 2 program video inputs.
Note: • SDI inputs selected must be used with Rear I/O Module
correspondingly equipped with intended input ports.
• Input select also allows internal connection from one
processing path output to the opposite processing path input.
This allows “serial” or cascaded processing connections
without requiring external jumpering on the rear panel. Serial
jumpering can, in addition to other functions, provide identical
program video output streams with a delay offset between the
two streams.
• Care should be taken to make certain an output from a video
path is not applied as an input for the same path. Also, if
framesync Lock to Input else Free Run is selected, the initial
“upstream” path must be selected using Lock to Input Path
control (for example, if Path 1 cascades to Path 2, this control
must be set for Path 1 as lock source).
• Unless upstream locked to same reference,
simultaneously-used inputs should be ref locked on this unit
using this unit’s Frame Sync function (see Framesync
(p. 3-18).
Input SDI Raster Size / Frame Rate Filtering
The controls shown below allow user filtering to exclude selected raster or rate formats from being received by an input.
SDI A thru SDI D and
CVBS Status show
raster/format for all
card inputs. If signal is
not present or is
invalid, Unlocked is
displayed. (These
status indications are
also propagated to the
Card Info pane.)
Input Format Disabled by User indicates raster size and/or frame rate
has been rejected from being passed by card (as described below in
Input SDI Raster Size / Frame Rate Filtering).
Default settings have all raster sizes and frame rates “checked”, thereby providing no filtering (exclusion.)
In the example below, only 720p and 29.97 are checked, filtering allowed input to only be 720p 29.97 (“720p half-rate”).
Note: Rates shown in selector are frame rates and not field rates.
