Dolby E Video Delay
The
PAM1-3G8
features a
1 frame (40 ms) video delay
setting which can be inserted
into the
Downconverted
video display to compensate for the latency caused by decoding
a
Dolby E
signal. If selected and activated, the delay will be switched into the video signal
path automatically when a
Dolby E
input signal is detected and decoded. The
Video
Confidence
window on
PAM1-3G8
will be subject to a
1 frame delay
when the video
delay mode is active.
