US 6,332,153 B1 · Apparatus and method for multi-station conferencing

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.

Dependent claims

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.
