SUMMARY OF THE INVENTION A need has therefore arisen for a conferencing system that provides for improved capabilities for exchanging data. The present invention provides a conferencing system comprising a plurality of endpoints communicating data including control data according to a communication protocol. A local endpoint may control or be controlled by a remote endpoint. The endpoints may comprise speakerphones, IP telephones, cell phones, video conferencing units, computers, conference bridges, or other communication devices.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1A depicts an exemplary block diagram of a conferencing system in accordance with one embodiment of the present invention.
DETAILED DESCRIPTION OF THE INVENTION As shown in the exemplary drawings wherein like reference numerals indicate like or corresponding elements among the figures, an embodiment of a system according to the present invention will now be described in detail.
According to one embodiment of the present invention, the digital link 360 couples the video conference unit 400 and the speakerphone 500 through the HSSB interfaces 449 and 549, respectively. There are two dedicated bidirectional buses in the HSSB: a data bus and a clock bus. The HSSB interface may send or receive in either direction. The physical layer of the link 360 preferably uses LVDS (Low Voltage Differential Signaling). LVDS is one of the many signaling standards capable of supporting high speed communication at low power consumption. In one embodiment, the HSSB is physically similar to an Ethernet connection, using Category 5 type of cable for the connection, i.e., a cable with unshielded four pairs of twisted copper wires. But the HSSB interface uses its own link protocol for transmitting data.

Referring now to FIG. 13, the audio signal frequency spectrum 1200 after being filtered by the notch filter 1106 is shown. A portion 1300 of the audio signal frequency spectrum 1200 has been-filtered out by the notch filter 1106. A modulated carrier signal 1400 is created for insertion into the portion 1300 of the audio signal frequency spectrum 1200, as shown in FIG. 14.
