Freeway
can handle video signals of either 525/60 standard or 625/50 standard
(analogue or digital). Some users wish to route both types of signal simultaneously.
Most routers only provide for a single video ‘house reference’ and this presents a
problem because a PAL reference cannot be used to ensure vertical (‘flash-less’)
switching of a 525/60 signal. The converse is also true.
Freeway
delivers maximum
flexibility by providing inputs for both PAL and NTSC ‘house reference’ signals.
Ideally colour-black, the ref signal may also be any stable video signal. Users may
assign which inputs are 525/60, and which are 625/50 via the configuration editor
(described later in this manual).
