Security Feature for Video Conferencing Applications

      In video conferencing applications, there are many times that
is required to ensure privacy during a session, one party may want to
conference in private.  users want the system to alert them to a call
rather than have a call be automatically answered and interrupt
another meeting confidential discussions are held in rooms with
microphones and  cameras and it is important that these devices are
not unintentionally  sending data out of the room.  It is
inconvenient (and undesirable) to  plug and un-plug mics and cameras.
It is also inconvenient (due to time  involved), to power equipment
up/down.  One way to deal with this problem  is shown in the figure
below:
   In the normal conference mode of operation (shown above), a
    status indicator (e.g., a light on the front panel of a box
    or an icon on the PC screen) shows that the conference is set
    up properly.  The user (or near end) camera sends its images
    to the far end.  Similarly, audio from the user is picked up
    by the microphones and sent to the remote participants.  Video
    and audio from the far end is connected to the users TV set
    and speaker, respectively.

      When one wants to ensure privacy, a switch is thrown which does
the following simultaneously:
     The normal operation indicator is removed and a privacy
    indicator takes its place.  a video switch disconnects the
    user video from the transmission circuit and inserts a far
    end notification sig...
