Apparatus and method for multi-station conferencing
First Claim
1. A method for multi-media half-duplex conferencing in a half-duplex conference server operating in a wide area network comprising a plurality of stations in communication with said half-duplex conference server, the method comprising the steps of:
- receiving at least one packet at said half-duplex conference server from at least one station of said plurality of stations said at least one packet including a digital representation of information comprising at least audio information;
detecting voice activity from at least one of said plurality of stations for identifying at least one of said stations of said plurality of stations as a transmitting station; and
responding to said detecting voice activity including;
blocking packets from all other stations of said plurality of stations at said half-duplex conference server, except from said one transmitting station; and
distributing from said half-duplex conference server, at least one packet received from said transmitting station to at least one of any other of said stations of said plurality of stations that are operatively coupled to said half-duplex conference server.

Abstract
A system and method for multi-media half-duplex conferencing in a computer network comprising a plurality of stations and a control server. The method and system include, respectively, means for and the steps of receiving a packet at the server from one station of the plurality of stations including a digital representation of information of at least one information type selected from audio information and video information, identifying the station as a transmitting station, blocking packets transmitted from the plurality of stations at the server except from the first transmitting station, distributing packets from the transmitting station, thereby providing audio information generated by a user of the transmitting stations to users of the other stations of the plurality of stations and repeating the steps of receiving, identifying, blocking and transmitting for a different one of the plurality of station, thereby replacing the transmitting station with a different transmitting station, thereby providing the half-duplex multi-station conference.

visually indicating to said stations the station which is said transmitting station.
-
-
3. The method of claim 2, wherein said step of visually indicating comprises the steps of:
-
transmitting at least one packet including a user identification from a station of said plurality of stations to said half-duplex conference server;
adding said user identification to a participants list of users participating in said half-duplex conference, thereby providing a current participants list;
storing said current participants list with an indication which station is said transmitting station;
providing said participants list to at least one of said stations; and
displaying said participants list including said indication of said transmitting station.
-
-
4. The method of claim 3, wherein said step of storing said current participants list comprises the steps of:
-
storing an update of said current participants list with an indication which station is said transmitting station;
retrieving said update by each of said stations; and
displaying said update and said indication of said transmitting station.
-
-
5. A conferencing system for multi-media half-duplex conferencing, operating in a computer network, said conferencing system including a half-duplex conferencing server comprising:
-
means for receiving at least one packet at said half-duplex conferencing server from one station of said plurality of stations, said at least one packet including a digital representation of information of at least one information type selected from audio information and video information;
a voice activity detector for identifying one station of said plurality of stations as a transmitting station;
means for responding to detected voice activity, said responding means configured for, blocking packets from all other stations of said plurality of stations at said half-duplex conferencing server, except from said one transmitting station; and
distributing from said half-duplex conferencing server, at least one packet received from said transmitting station to at least one other station of said plurality of stations. - View Dependent Claims (6, 7, 8)
means for visually indicating to said stations the station which is said transmitting station.
-
-
7. The system of claim 6, wherein said indicating means are configured for:
-
transmitting at least one packet including a user identification from a station to said conferencing server;
adding said user identification to an identification list of users participating in said half-duplex conference, thereby providing a current participants list;
storing said current participants list with an indication of which station is said transmitting station;
providing said participants list to at least one of said stations; and
displaying said participants list including said indication of said transmitting station.
-
-
8. The system of claim 7, wherein said indicating means comprises:
-
means for storing an update of said current participants list with an indication which station is said transmitting station;
means for retrieving said update in each of said stations; and
means for displaying said update and said indication of said transmitting station.
