1. A universal bridge for a multimedia conferencing system, comprising:
- an interface, configured to carry streams of transport frames according to a transport protocol, each frame having a stream identifier;
a media relay input processor, coupled to the interface and configured to deliver to the interface transport frames carrying compressed media received from a media relay endpoint;
a decoder module, coupled to the interface and configured to obtain a stream of transport frames carrying compressed media and generate a stream of transport frames carrying decoder module data units;
a first type media combiner module, coupled to the interface and configured to combine a plurality of streams of transport frames carrying decoder module data units into a stream of transport frames carrying combined media targeted toward a legacy endpoint;
an encoder output module, coupled to the interface and configured to obtain a stream of transport protocol frames carrying decoder module data units and generate a stream of transport frames carrying compressed media;
a media relay endpoint output processor, coupled to the interface and configured to obtain one or more streams of transport frames carrying compressed media originated by a first media relay endpoint or a first legacy endpoint and deliver one or more streams of packets toward a second media relay endpoint; and
a control module that controls data traffic to and from the interface and allocates stream identifiers for streams of transport frames.

Abstract
A novel universal bridge (UB) can handle and conduct multimedia multipoint conferences between a plurality of MREs and LEPs without using an MRM, an MCU and a gateway. Further, a UB can be configured to allocate and release resources dynamically according to the current needs of each conferee and the session.
