摘要： A method for preventing movement in a telepresence system, includes a plurality of cameras. Each camera has a respective field of vision for viewing one or more users. The fields of vision each have lateral boundaries. The system also includes a plurality of restrictive elements. Each restrictive element is positioned along a respective lateral boundary of a field of vision of the fields of vision of the plurality of cameras such that viewed users each positioned within a field of vision of the plurality of cameras are restricted by the plurality of restrictive elements from moving outside of the field of vision in which each viewed user is positioned.

摘要： A display device may reduce the latency of the display of a digital signal by reducing the latency that the display device adds to the digital signal. After a digital signal is received by an input module, the signal is stored in a frame buffer as a plurality of pixels. A controller determines the input frame rate of the digital signal and a pixel delay. The controller monitors the frame buffer to determine when the frame buffer has stored a number of pixels greater than or equal to the pixel delay. After the frame buffer contains enough pixels, the controller initiates transmission of the pixels from the frame buffer to a display module. In certain embodiments, the controller initiates transmission of the pixels to the display module before the frame buffer has stored all pixels corresponding to the frame.

摘要： Methods and systems that compensate for display latency when separate speakers are used during video conferencing. A method includes determining whether speakers, which are not controlled by a display, are to be used in connection with a video conferencing session. The method further includes sending, to the display, data that causes the display to generate a predetermined pattern, capturing imagery of the effects of the predetermined pattern shown on the display, calculating a latency of the display based on a difference in a time the data was sent and the imagery of the effects is received, and storing a value of the latency of the display in a device that enables the video conferencing. When the speakers, which are not controlled by the display are selected, are selected, the audio portion of the video conferencing session is redirected to those speakers, but delayed for an amount of time substantially equivalent to the value of the latency of the display. In this way audio and video synchronization may be improved.
