摘要： An apparatus is provided in one example and includes a camera configured to receive image data associated with an end user involved in a video session. The apparatus further includes a display configured to interface with the camera. The camera and the display cooperate such that the apparatus can initiate the video session involving the end user, and activate a retracting mechanism configured to move the camera such that the camera is retracted from a view of the display and the camera moves to an inactive state.

摘要： A method, an apparatus, and logic for testing a video data path. One method includes sending video data corresponding to a video test pattern to an input port of a video data path; receiving video data at an output port of the video data path; and calculating a function of at least the active part of the received video data. The function is selected such that it has a correct value when the at least the active part of the received video data accurately corresponds to the corresponding part of the sent video data. The method further includes ascertaining whether the function of at least the active part of the received video data has the correct value to ascertain whether or not an error has occurred.

摘要： A system for enhancing eye gaze in a telepresence system includes a plurality of local cameras coupled to at least one local display. Each local camera is directed to at least one respective local user section and operable to generate an image of the respective local user section. The system also includes a plurality of remote displays. Each remote display is operable to reproduce the local video image of the local user section. Within the system the plurality of remote displays and the plurality of local cameras are aligned such that when a first local user within a local user section looks at a target at least one remote display is operable to reproduce the local video image of the first user section comprising the first local user such that the eye gaze of the reproduced image of the first local user is directed approximately at a corresponding target.
