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

Method for control of a video interface, method for operation of a video interface, face orientation detector, and video conferencing server

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.
