A method for implementing real time communication between two users by separately transferring multiple video media streams to different devices used by one user of a conference system comprising a conference system server, wherein each media stream of the multiple media streams relates to the conference and is sent to the conference system server by a different conference attendee, the method comprising: loading, by a browser of a first device used by the user, a Web application of the conference system: searching, by the browser, for at least two second devices of the user that may be configured to present a media stream; sending, by the browser, to the Web application, obtained information about at least two second devices of the user that may be configured to present a media stream; sending, by the browser, Session Description Protocol, SDP, Offer information to the conference system server by using the Web application, wherein the SDP Offer information carries indication information indicating that the user is a multi-device user; receiving, by the browser, SDP answer information from the conference system server; obtaining, by the browser, the multiple media streams from the conference system server, wherein the obtained multiple media streams have not been mixed by the conference system server; parsing, by the browser, the obtained media streams and presenting the obtained media streams to the user; receiving, by the browser, a media stream transfer request from the user by using the Web application, wherein the media stream transfer request indicates that the user designates a first specific media stream to be sent to a first selected second device of the user and a second specific media stream to be sent to a second selected second device of the user; marking, by the browser, each obtained media stream according to the media stream transfer request; transferring, by the browser, the first specific media stream to the first selected second device and the second specific media stream to the second selected second device. searching, by the browser, for at least two second devices of the user that may be configured to present a media stream; sending, by the browser, to the Web application, obtained information about at least two second devices of the user that may be configured to present a media stream; sending, by the browser, Session Description Protocol, SDP, Offer information to the conference system server by using the Web application, wherein the SDP Offer information carries indication information indicating that the user is a multi-device user; receiving, by the browser, SDP answer information from the conference system server; obtaining, by the browser, the multiple media streams from the conference system server, wherein the obtained multiple media streams have not been mixed by the conference system server; parsing, by the browser, the obtained media streams and presenting the obtained media streams to the user; receiving, by the browser, a media stream transfer request from the user by using the Web application, wherein the media stream transfer request indicates that the user designates a first specific media stream to be sent to a first selected second device of the user and a second specific media stream to be sent to a second selected second device of the user; marking, by the browser, each obtained media stream according to the media stream transfer request; transferring, by the browser, the first specific media stream to the first selected second device and the second specific media stream to the second selected second device.
