Definitions

  • the present invention relates to a conference system comprising a central unit and at least one delegate unit connectable to the central unit.
  • a conference system includes a central unit in connection with several delegate units for the participating delegates.
  • the central unit serves to combine audio channels from various delegate units and for distributing the received audio and data channel and combinations of these channels.
  • these delegate units are connected to the central unit either by using a fully wired or a fully wireless infrastructure. It is not possible to use a mixture of both. This substantially reduces the flexibility of the digital conference system.
  • Patent application WO2005/117409 relates to a conference system comprising a central unit and speaker units connectable to the central unit.
  • the central unit is provided with an adaptive filter for suppressing feedback.
  • Each speaker unit comprises an adaptive filter coupled between a microphone and a loudspeaker.
  • the adaptive filter serves as an echo canceller, while serving as a feedback suppressor when the speaker unit is activated.
  • the second connection means comprises an output connector for connecting an external antenna.
  • the invention in another aspect relates to a conference system comprising a central unit as previously described and at least one delegate unit as described.
  • Fig. 3 represents a general view of the conference system according to the present invention.
  • the add-on module (10) for operation in wired mode comprises the specific components required for making the delegate unit (1) operable as a wired unit :
  • Each audio channel (floor channel, interpreted channels) has a fixed position in the frame. These frames are transmitted on the wired network with a LVDS link. Therefore on the add-on module an LVDS network driver and receiver is necessary.
  • the interface between motherboard and add-on module is modified in a way that data communication is possible between the processing unit on the motherboard and network drivers. In this example this can be LVDS (low voltage differential signalling) or TTL logic depending on the network drivers and receivers used. Placing the delegate units in daisy chain makes it possible for each delegate unit to receive the transmitted data from the central unit and, if needed, to add data in the uplink stream. At system start-up the motherboard learns which module has been connected by reading the identifier on the module.
