Fiber1 3G Detect This parameter configures 3G operation of the Fiber 1 video input. The input can be
set for 1080p50/60 (single video), Dual Stream 3G SDI (two muxed videos), or Auto-
Detect whether the input is 1080p50/60 single or Dual Stream 3G video (requires
SMPTE Format ID to be present in the SDI Input). See parametr 4 SDI 1 3G Detect for
an illustration and details.
Fiber2 Input
Protect This parameter allows you to protect Input Fiber 2 from being taken by a Dual
Stream selection made in 6 Fiber1 3G Format Detect setting.
In the Normal setting (default), the Fiber 2 video signal always comes from the SDI 2
physical input. Choosing Dual Stream video in parameter 6 does not switch away
from the physical input.
In the Dual Stream setting, the FS2 assumes both channels of Dual Stream 3G video
are muxed onto a single wire at the Fiber 1 input. The Fiber 2 video signal is then
taken internally from the Fiber 1 Channel 2 signal instead of the Fiber 2 Input
connector.
Genlock Source Genlock Source selects the source of reference video used to genlock to, either
automatically or explicitly.
Note: HDMI can be used as a reference (with SYSTEM 8 Genlock Source set to Vid1
Input or Vid2 Input), but HDMI is not a valid reference source when the signal on
the HDMI input originates from a VESA-format computer DVI signal.
