Quad Viewer
As a standard feature, Mira includes a built-in Quad Viewer which displays the outputs of a set of four video channels on a single dedicated
digital video output. This Quad Viewer appears on a dedicated HD-SDI digital video connector on the Mira server rear panel.
The Quad Viewer only appears when Mira is operating in HD video formats, 720 or 1080. The Quad Viewer output is disabled when Mira
is operating in SD video formats, 525 or 625. If you will be operating Mira in standard definition, then please use the desktop Viewer that is
built into the Mira Explorer user interface instead of this Quad Viewer.
To locate the BNC connector that supplies this Quad Viewer image, please refer to item “(J)” in the illustration found in Figure 1 on page
19 above. Mira 8-Channel servers feature two of these BNC connectors: one for ChA-ChD; the other for ChE-ChH.
The four video images are full-motion low-resolution images of the four video channel outputs. Superimposed over each video channel is a
status display which includes the following:
A.Channel Label (ChA, ChB, ChC, ChD) and (ChE, ChF, ChG, ChH) for the Mira 8-Channel server.
B.Calibrated Audio Metering (8-Track audio is standard; 16-Track audio is optional)
C.“Play Speed / RECORDING” Indicator (the illustration below shows ChA-ChC with the RECORDING indicator; ChD is shown with
play speed indicator)
D.Clip Name (length varies, according to Clip Name; if length of Clip Name is very long, then the right end of the Clip Name will be
truncated)
E.Timecode (field mode is appended with “f1” or “f2”; frame mode is appended with “f1-2”)
The opacity of the text and black rectangles within the status overlay can be adjusted in the Mira Engineering Setup menu. These overlay
characters and background can be made semi-transparent, so video images behind the overlay can be made visible through the overlay.
Please refer to the procedure “Engineering Setup — Quad Viewer” on page 220 above to change the overlay opacity.
The illustration in Figure 10 below provides a sample image of the Quad Viewer output.
