    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;
