Audio Meter Window
The Audio Meter window displays VU meter, PPM meter or mixed
VU/PPM (a VU meter with a top bar showing the PPM value). Enable
the audio meter window through
OSD_VUDisp .
When you select VU meter or PPM meter, a white bar on the top
indicates the peak hold value. It holds for one second in 525-line
standard and 1.2 seconds in 625-line standard.
The audio meter shows the audio levels for both the left and right
channels. Each channel displays three sections, colored red, yellow and
green. Adjust the level of top of yellow and top of green through
OSD_VUYTop and OSD_VUGTop , respectively. Adjust the position
of the audio meter window via OSD_VUPosX and OSD_VUPosY and
use OSD_Opaque to adjust its opacity.
String Display
With an RS-422/Ethernet controller, the DVR-3901 can write strings
(for example, a clip name) for display on the on screen display. Refer to
the
DVR-3901 Automation Control Developer’s Manual for more
information.
