A High Speed Serial Bus connecting teleconference devices, such as video conference unit, speakerphone, external loudspeakers or microphones is disclosed. The disclosed embodiments enable the distributing and sharing of controls among the linked devices. They enable incremental upgrades or capacity increases of the teleconference system.

Method and apparatus for combining speakerphone and video conference unit operations

A conference link between devices in teleconference system at one site is disclosed. The linked devices include video conference units, speakerphones or stand-alone loudspeakers. Audio data can be transmitted through the conference link between devices. Audio data processing can be performed in either a video conference unit or a speakerphone. The microphones and loudspeakers in the video conference unit may be eliminated. The microphones and loudspeakers in the speakerphone are used. Other data, for example directories of dialing information, may also be transmitted through the conference link and the data processing may be allocated among processors in devices connected by conference links. The conference link may be wired or wireless, analog or digital. The devices may be linked by conference link in parallel or series. A dialing program can adapt the dialing stream with the locations of the near end site and the dialed far end site. The dialing program can automatically select a mutually supported network or protocol to establish a connection between two sites.
