DESCRIPTION: After loss of input video is detected, a preset delay
can be set before the page of text defined by the LP (Loss P

command is displayed. This applies only if the Loss Detect (LD)

the unit. Code 1 (white noise) is used when, upon loss of video, the
input becomes white noise such as loss of signal from a satellite feed or
the end of a tape on a VCR. Special software within the unit analyzes
the noise to determine if valid video (sync) is present or if it is just
random noise.
