The eavesdrop server handles receipt of images from the local rtdServer, image processing prior to the transmission of image data (this may include compression or conversion to X colour data), transmission of data to active clients using RMP, as well as interaction with the eavesdrop server operator and acknowledgement of clients.
To run the multicast server, go to the INSTALL_DIR/lib/rtd/demos directory and type rtdmcserv.
In order for the eavesdrop server to become "visible" to remote clients, it must first be connected to a local CCD. To do this, select the required camera in the LabelMenu (this list is formed from the configuration file discussed in the previous section) and invoke the "Connect" toggle button to the side of this. After a short time, a message will appear on the server transcript window to the effect that a new RMP group has been created and the camera LabelMenu will become inactive. Disconnection from a camera is possible by reinvoking the "Connect" button, after which the label menu will become active again.
Images will be received from the connected camera when remote clients connect to the eavesdrop server. Diagnostic messages will appear on the transcript window as clients connect and disconnect to the server and images are transmitted.
