1. OVERVIEW
In live shows there is always the risk that certain actions, on the part of an artist or an intruder, might be
offensive to certain viewers. The Evertz HDSD9545DLY-PRO Profanity Protection device is designed to
give an operator complete control over the program content being broadcast to air.
The HDSD9545DLY-PRO enables the operator to insert the desired time delay, via a front panel control
and a display panel. There are two program paths that are HD and SD compatible. The main program
feed will usually be focused on the main detailed action. The secondary back-up path will generally offer a
wide angle shot, or some suitable alternative picture to the main content. Both channels are delayed by
the same amount of time. If an unscheduled, offensive event occurs, the operator has only to hit one
remote button to cause the program video and audio output to be clean switched to the alternative back-
up channel. When the offensive material is no longer present, the output can be returned to the main
detailed image, without the audience noticing that an edit has occurred.
On the standard unit the delay can be adjusted up to a maximum of 24 seconds for HDTV or SDTV. The
user can allocate this maximum delay to primary and secondary paths. Typically it is set for max 12
seconds primary and max 12 seconds secondary. When the –HD40 option is added, the delay can be
adjusted up to a maximum of 40 seconds for HDTV or 240 seconds for SDTV.
The HDSD9545DLY-PRO includes a built-in HD/SD quad split output that shows all four pictures on one
monitor. The four pictures are as follows:
