<p>A multipoint multimedia server (130) includes a number of different compression codecs (134), a multipoint switch (132), separate audio (136) and video (138) processors, and at least one controller (140). Data streams of different compression standards enter the server (130) wherein the data streams are directed to the appropriate codec. The signals are mixed and switched by the controller (140) and the multipoint switch (132) and then routed back to the appropriate codecs. The signals are recompressed to the appropriate standard for each user before exiting the server (130).</p> |
