Abstract

A hub (4) for multimedia multipoint video teleconferencing includes having a plurality of input/output ports (22), each of which may be coupled to a communication channel (12) for interchanging teleconferencing signals with remote sites (2). The hub (2) includes a plurality of signal processing functions (30) that can be selectively applied to teleconferencing signals so that the signals distributed by the hub (4) are in a form desired by the recipients or required by their equipment. Signal processing may include video, data, graphics, and communication protocol or format conversion, and language translation. The hub (4) may generate data (82) relating to the use of its processing capabilities during a teleconference, so that accounting or billing for a teleconference may be based at least in part on which hub resources were used, the extent of their use, and the person desiring their use. The identification of a signal processing function (30) to be used during a teleconference may be automatically performed in response to the content of signals received at the hub (4) during the teleconference.
