6 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 parameter 4 SDI 1 3G Detect for an illustration and
details.
7 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.
8 Genlock Source
This parameter 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.
9 Frame Rates
This parameter selects the HD video frame rate associated with the video standard.
NOTE: Changing the Frame Rates selection automatically selects a new value for 2 Output Format.
Each Frame Rates selection remembers its own Output Format settings.
Auto Detect (default)
1080p50/60
Dual Stream 3G
Automatically detects presence of 1080p50/60 or muxed
video.
Configures the Fiber 1 input for 1080p50/60 video.
Configures Fiber 1 for Dual Stream 3G Video (uses SDI1 and
SDI2 in Input Crosspoint matrix).
Normal (default)
Dual Stream
Fiber 2 cannot be used by Dual Stream 3G SDI video present
on Fiber 1.
Allows Fiber 2 to be used by a Dual Stream 3G SDI input
present on Fiber 1.
Reference (default)
Vid1 Input
Vid2 Input
Free run Use the signal on the Ref connector as the genlock source.
Use the Vid1 input signal as the genlock source.
Use the Vid1 input signal as the genlock source.
Free run mode (FS2 syncs to its own timebase, not locked to an
external source).
59.94/23.98 (default)
50/25
60/24 Select 59.94/23.98 if your desired rate is either 59.94 or 23.98.
Select 50/25 if your desired rate is either 50 or 25 (PAL).
Select 60/24 if your desired rate is either 60 or 24.
