Parameters

expand all

Specify the IPv4 address of the computer to which you send the video frames. To broadcast the video frames to all listening computers, enter 255.255.255.255. The Remote IP port to send to parameter specifies the port for the destination.

Specify the computer port to which you send the video frames. The IP address sent to (255.255.255.255 for broadcast) parameter specifies the IP address for the destination.

Specify the computer port from which to send the video frames.

To assign automatically a port for the computer, enter -1.

Select this check box to enable the transmission of variable-length frames. For example, use this option for compressed frames because the length of each frame varies.

If you select this check box, the Data port sends the actual data. The Length input port sends the number of bytes being transmitted. If the port size is less than Length, the block sends up to the port size.

If this check box is not selected (default), the block sends only fixed-length packets.

Dependency

Selecting this parameter displays the Length output port.

Enter the base sample time or a multiple of the base sample time. -1 means that sample time is inherited.
