Claim:
1. A method for a set-top box implementing a multi-party conference call, comprising: in a conferencing state, a first set-top box sending to a network server that is used to manage a conference a request message for adding a second set-top box into a conference where the first set-top box is located; the first set-top box receiving an acknowledgement message fed back by said network server for indicating that said second set-top box has joined the conference; said first set-top box sending an HTTP message to said network server to request to add a third set-top box into the conference; said network sever sending a join-in conference request to said third set-top box; said third set-top box returning a join-in conference acknowledgement message to said network server; said network server returning the join-in conference acknowledgement message to said first set-top box, meanwhile notifying said second set-top box that said third set-top box newly joins in the conference where said second set-top box is located; and sending audio and/or video signals to be transmitted by said first set-top box to said network server which converts the audio and/or video signals into multiple-channel parallel signals and distributes the multiple-channel parallel signals to other members of said conference by HTTP connection.
