Abstract: The present invention relates to a method for control of a video interface (4) associated to a user (12) for use in conference situations and the like, comprising the steps of capturing a frame (11) of a video stream originated from the user (12), recognizing a face (10) of the user (12) within the video frame (11), detecting an orientation of the face (10) of the user (12) within the video frame (11), and providing a control signal indicating the orientation of the face (10). The invention also relates to a method for operation of the video interface (4) comprising the steps of the above control method, mapping the orientation of the face (10) based on the control signal to a focus area (15) of the video interface (4), and highlighting the focus area (15). The invention further relates to a face orientation detector (6) and a video conferencing server (5), which are adapted to perform the above methods.

Abstract: A method for monitoring transmission characteristics in a network including a media client, a media server, and a data processor, the method including establishing a connection with the data processor; establishing an end-to-end encrypted channel between the media client and the data processor for exchanging streaming media content over the connection; sending a probing message to the data processor over the channel, the probing message carrying a first timestamp indicating the sending time of the probing message; receiving a response to all of the probing message from the data processor, the response carrying a second timestamp indicating the arrival time of the probing message at the data processor; and deriving latency information, including an upstream latency between the media client and the data processor, from a difference between the second timestamp and the first timestamp.
