Internal
The internal setting allows an overall refresh rate for the processor to work at, which can be
23.98, 24, 25, 29.97, 30, 50, 59.94 and 60 fps, irrespective of the frame rate of sources coming
in to the processor. The processor will automatically compensate where the source frame
rate and the internal refresh rate are different
.
Reference In
The M Series processor can synchronise its system and panel refresh to an external bi-level
or tri-level reference. The processor will automatically compensate for sources that do not
match the refresh rate of the external reference.
Locking to Video Inputs
Tessera processors can lock the processors internal refresh and fixture refresh to the
refresh rate of an incoming source, whether it be on the DVI-I input, or in the case of the M
series processor additionally on either of the two SDI inputs. The processor will automatically
compensate for sources that do not match the refresh rate of the selected source.
Note:îIf the frame rate of the incoming video input is different to the reference, be it internal,
another video input or a bi-level or tri-level sync, then the processor will match the referenced
frame rate by either doubling frames or dropping frames depending on whether the incoming
frame rate is less than or greater than the reference frame rate. There is no guarantee that
every processor will do this at the same time. For critical synchronisation between two or more
processors then the incoming frame rate should match the referenced frame rate.
