Continuous Presence (or CP for short) is a method used in video conferencing whichbasically means that all participants, or a subset of these participants, including the active speaker, are seen on the screen at the same time.

CP involves a lot of graphical manipulations on the streams received by the different endpoints, including scaling and mixing the images. Today, with SVC technology, CP can be achieved without graphical manipulations, but only in closed H.264-based deployments, which are still not common.
