Spigot Pages
The Spigot pane details:
• Spigot direction;
• Associated BNC connector;
• Current status;
• The last Take performed on the spigot.
Streaming
Select the Ethernet connectors to use for this spigot. This will also determine the bandwidth to
be used. Options are:
• Dual - use both Ethernet connectors, and so all available bandwidth.
• Single - use either Ethernet connector, and so half of the available bandwidth.
• A or B - use one particular Ethernet connector, and so half of the available bandwidth.
Format
Select the format to be used on this spigot. This will ensure that the appropriate level of
bandwidth is allocated.
Video Standard
Select the standard for the incoming video, or set to Auto to detect the standard automatically.
Num Audio Channels
If the number of audio channels is known, select the number present on this spigot. Otherwise,
set to
Auto .
Audio Delay
Move the slider to set an Audio Delay as required. Click P to return to the preset default value.
Make/Break Mode
Specifies how changes to an output’s destination will be made. Make before Break causes the
new destination to buffer data before connection to the previous destination is broken; this
results in a smoother transition, but requires more bandwidth.
Break before Make simply
swaps the output’s destination without buffering.
Select the required mode from the drop-down list.
Flow Pane
The Flow pane provides status information for video, audio and metadata. It also allows the
flow type, loopback and multicast IP/port details to be defined for the selected spigot.
Note: It is important to use the Auto setting unless the actual number of
audio channels in the stream is known definitively. Setting an
inaccurate number of audio channels may result in unpredictable
behavior.
