Overview
Where signals from more than one source are to be processed, it is essential
that these signals are precisely synchronised and perfectly in-phase, prior to
processing. Within certain specified tolerances, described later, Imagestore is
able to automatically re-synchronise the signals that are applied to its three
signal inputs.
As signals pass through Imagestore, or any other equipment, they are
unavoidably subjected to a propagation delay. The value of the delay may
vary depending on the mode configuration of the unit and will certainly be
affected if an EasySound/EasyPlay audio mixer card is installed. Rather than
exhibiting a non-quantifiable propagation delay, Imagestore is provided with
a timing adjustment that enables the integrator or user to set a specifically
determined propagation delay through the unit. This timing adjustment may
be used to match an Imagestore to the propagation delays of other
Imagestores or of other broadcast equipment.
Miranda Technologies Ltd always recommends the use of a separate
analogue, "Black and Burst", reference signal for timing all the equipment
within a system. Where this method of timing is used, it is common for the
reference source to be located some distance from the Imagestore and it is
possible that the synchronisation of the SDI input signals and the "Black and
Burst" reference may be displaced by several video "lines". Where this
preferred form of timing is chosen the Imagestore timing adjustment is given
a second parameter to allow for the potential "line" discrepancy.
Timing Adjustment
The timing adjustments available for Imagestore do not affect the automatic
synchronisation of input and output signals. The set-up adjustment simply
controls the value of propagation delay through the Imagestore.
Where analogue reference is selected an additional parameter providing for a
line correction factor becomes available. The following paragraphs discuss
the adjustments in detail.
