1. A method for interfacing a plurality of videoconferencing client devices comprising a video routing client and a video mixing client, wherein said mixing client comprises a Multiparty Conference Unit able to receive a plurality of client video streams and to generate a mixed video stream by mixing said plurality of client video streams the method comprising, in a computer server connected to the client devices:
receiving a first client video stream from the video routing client; tagging a video image of the first client video stream received from the video routing client, sending, through a bidirectional communication channel, the first client video stream to the mixing client, receiving, through the bidirectional communication channel with the mixing client, a mixed video stream from said mixing client, detecting in the mixed video stream received from the mixing client a video image portion which is different from the tagged video image of the first client video stream, extracting the detected video image portion from the mixed video stream, generating a second client video stream from the extracted video image portion; sending the second client video stream to the video routing client. |
