Multicasting of Images to Remote Sites

Note that the RMP package is currently not yet available!

In this appendix, we discuss the multicasting of images to remote clients. This is an extension to the "local" RTD functionality: the applications and widgets detailed below are not an integral part of the RTD and are not required by the RTD in normal operation.

In short, the multicasting functionality allows users to receive images from designated remote image servers. A multicast server process can be started on any machine on which a CCD is creating image data. Client processes can browse for any available servers and connect to the required remote camera, after which images will be received at time intervals governed by the server process operator. Several options and formats exist for the image transmission; these are discussed in more detail below.

The multicasting applications are contained in the RTD release but they do not have to be installed. See the installation notes for more information.
