This feature allows two or more instances of Viz Engine on one system to show the same content by using the same physical input without the need for a distribution amplifier.

Configuration

To share the input, all instances must have their corresponding input channels configured the same to be used.

Example: Matrox0.VideoIn1.MapToVizChannel = 0

Important

The first instance of Viz Engine that is started owns the physical connector of the input. All other instances started after share the content on the video board. If the first instance (in control of the input connector) is closed, all other instances referring to that connector lose their content as well, and need to be closed and restarted again. There is no automatic recovery when the owning instance of Viz Engine crashes.

It is required to set the flag Matrox.InputHost = 1 (Matrox section) in the first instance to be started. As the startup sequence is not clearly defined, it is recommended to add this flag to all instances.

The delay increases by one frame.

Note: It is imperative that the first engine fully boots before the others can allocate the shared resource.

Watchdog configuration is also not supported in this case.

Info: This feature is available on system topology boards only (xMio3, DSX.LE4 and successors).
