• 3.7 Video references - BNC sockets (looping)
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).
