About Re-Entry
Normal Re-Entry permits the switcher to select the output of one M/E for use as an input
source to another M/E. The signals are routed internally. Enabling Re-Entry allows the
secondary or primary output of an ME to be used as an input for the other side of the
same ME. (Secondary into the Primary or Primary into the Secondary).
A Grass Valley switcher system supports M/E re-entry in any order. For example, an output
of ME-2 can be sent to ME-1, and an output of ME-1 can be sent to ME-3. Infinite looping re-
entry (for example, ME-1 sent to ME-2 and ME-2 sent back to ME 1) is allowed but should
only be done carefully
About Source Patching
Facility engineers need to know the exact routing of all the video signals connecting all the
devices they are responsible for. These engineers need to be able to identify video signals in
a way that will help them connect devices properly. Production personnel, on the other
hand, are interested in the content they work with for their shows, and are generally not
concerned about which individual device or routing path is used to make those signals
available. They just need a way to identify the content and access it when they need it. To
support these differing needs, two source naming mechanisms are available on GV
Switcher systems; Engineering Source ID and Logical ID.
