Reference Source Selection
To operate as part of a broadcast system, or to operate stand-alone,
Imagestore digital video frames must be synchronised to a reference source.
Miranda Technologies Ltd recommends the use of a common analogue
"black and burst" reference source. Once the initial phase-lock has been set
up, phase locked loop circuits within the Imagestore automatically maintain
the synchronisation.
The alternative to a common analogue reference source is to use the
background SDI signal as the source of timing. This may be more suitable
where the unit is used within a simple presentation system.
To check or change the setting, choose Select Reference from the System Set-
up menu and press the enter key. The current setting is shown enclosed in
brackets. To return to the "boot-up" menu, press the escape key repeatedly.
To change the setting, use the arrow keys
