Abstract: A near-eye-display (NED) includes a tracking system and a waveguide assembly. The waveguide assembly includes an infrared (IR) light source and an output waveguide. The output waveguide includes at least a decoupling element that outcouples the IR light emitted by the IR light source to form the structured light pattern. The structured light pattern is projected toward one or more regions of a user's face, for example, the user's eyes. The structured light pattern is reflected off the one or more regions of the user's face and captured by the tracking system. The tracking system can determine tracking information such as eye tracking information as well as face tracking information based on the captured reflected structured light pattern.

The QP value is variable such that varying the QP value controls a degree of masking of the ROI.

Abstract: Entropy coding/decoding techniques are disclosed in which data is coded alternately as a series of nonzero values and zero values until the transmitted data is consumed. Nonzero values may be coded first with transmission of data identifying a number of consecutive nonzero values that appear in scan order followed by transmission of the nonzero values themselves. Thereafter, if other data remains to be transmitted, data may be transmitted identifying a number of consecutive zero values that appear next in scan order followed by transmission of a next nonzero value encountered in scan order. By transmitting the nonzero values as a group, it is expected that the proposed entropy-coding process will achieve higher efficiency than competitive techniques.

More specifically, embodiments of the present invention relate to a method of triggering or activating a video camera to record and/or transmit images of a physical environment over a network only when measurements taken by a separate structural sensor camera or depth-sensing device indicate that sufficient physical changes have occurred in the environment to warrant video recording.

Abstract: A video encoding method eliminates the need for back channel feedback by using long-term reference frames for recovering data transmission errors. A videoconferencing endpoint captures image data and designates a first frame as a long term reference (LTR) frame. Subsequent intra frames us the LTR frame for reference. When a new LTR frame is designated, subsequent frames use the newly designated LTR frame for reference only after it is determined that the newly designated LTR frame is fully operational to serve in that role.
