| 20110298965 | SCENE-AWARE AUTOMATIC-EXPOSURE CONTROL - A scene-aware auto-exposure control process stabilizes changes in a camera's auto-exposure settings so as to reduce lighting and color flicker during image capture operations. A metric, referred to as the Modified Adjusted Luminance (MAL) metric, is defined to remain relatively constant as long as the lighting of the scene being captured remains relatively constant. Thus, scene changes such as an object moving into, out of, or around in a scene do not significantly affect the MAL metric's value and do not, therefore, trigger an exposure adjustment. Once the MAL metric indicates a scene's lighting is stable, the camera's auto-exposure operation may be suppressed. As long as incoming frames indicate a stable lighting condition (based on the MAL metric), auto-exposure operation may remain suppressed. When incoming frames result in a substantially different MAL over a specified number of frames, auto-exposure operation may be restored. | 12-08-2011 |

| 20110298886 | Auto Exposure Techniques for Variable Lighting Conditions - Systems, methods, and a computer readable medium for performing auto exposure (AE) techniques that are beneficial in variable lighting conditions—and particularly applicable to handheld and/or mobile videoconferencing applications—are disclosed herein. Handheld and/or mobile videoconferencing applications—unlike their fixed camera counterparts—are often exposed to a wide variety of rapidly changing lighting and scene conditions, and thus face a difficult trade-off between adjusting exposure parameter values too frequently or not frequently enough. In personal electronic devices executing such handheld and/or mobile videoconferencing applications, it may be desirable to: use a small, centered, and center-weighted exposure metering region; set a relatively low brightness target value; and adjust the camera's exposure parameter values according to a distance-dependent convergence speed function. The use of such techniques, in conjunction with a relatively large stability region, may also improve the quality of a video encoder's temporal predictions—and thus video quality—in videoconferencing applications. | 12-08-2011 |

According to the present invention, an encoder designates a reference frame as a long term reference (LTR) frame and transmits the LTR frame to a receiver. Upon receiving feedback from the receiver acknowledging receipt of the LTR frame, the encoder periodically codes subsequent frames as reference frames using the acknowledged LTR frame as a reference and designates subsequent reference frames as secondary LTR frames. A determined number of frames after each secondary LTR frame may be coded using a preceding secondary LTR frame as a reference. | 10-13-2011 |

The statistics information may comprise a collection of data values, calculated statistics, or instructions for the suggested post-processing adjustments. Accumulated supplemental information may be transmitted from the encoder to the decoder via an out-of-band channel, associated with the encoded video sequence transmitted on a communications channel. | 12-08-2011 |
| 20110299605 | METHOD AND APPARATUS FOR VIDEO RESOLUTION ADAPTATION - A system and method for gradually changing the resolution of a video signal to avoid a large spike in the video data transmitted between an encoder and a decoder. Upon detection of a change in the quality of source video, of the quality of the encoding process, or of the channel conditions, any of which may negatively impact the rate of frame transmission from encoder to decoder, or the quality of frames transmitted, a responsive change in the resolution of the video frame may be gradually implemented. To change the resolution by increasing the effective image size, each successive frame in a sequence of frames may contain additional pixel blocks in the expansion image area at the new resolution. In an embodiment, the decoder displays the video image at the original resolution until the resolution switch has been completed. | 12-08-2011 |
| 20120170654 | VIDEO CODING SYSTEM USING IMPLIED REFERENCE FRAMES - A video coding/decoding system builds implied reference frames from a plurality of reference frames developed during coding.

Thereafter, coding of new input data may proceed using the implied reference frame as a source of prediction. The method may be used to identify visual elements such as background elements that may persist in video over a longer period that can be captured by the system under conventional reference frames assembly and eviction. Implied reference frames may be built at both an encoder and a decoder to serve as sources of prediction. | 07-05-2012 |
| 20120207214 | WEIGHTED PREDICTION PARAMETER ESTIMATION - Video coding systems incorporate techniques for deriving scalars W and/or O for use in weighted prediction. W represents a scaling factor and O represents an offset value. Given a frame of input video to be coded, a prediction match may be established one or more reference frames. The input frame may be parsed into a plurality of regions. Thereafter the scaling factor W and/or offset value O may be derived by developing a system of equations relating a predicted pixel to the pixel in the frame by the scaling factor W and/or offset value O. Equations within the system may be prioritized according to priority among regions, and scaling factor W and/or offset value O may be solved for. The scaling factor W and/or offset value O may be used during weighted prediction of the input frame. | 08-16-2012 |
| 20130027581 | ADAPTIVE AUTO EXPOSURE ADJUSTMENT - Techniques for adjusting exposure parameters of a camera such that video data captured by the camera may be coded efficiently.

| 20090279652 | Synchronizing Clocks Across a Communication Link - Apparatus, system and method for synchronizing one or more clocks across a communication link. A slave clock may be synchronized to a master clock by means of a synchronization signal sent from the master to the slave clock side of the link. The synchronization signal may be an expected signal pattern sent at intervals expected by the slave side. The slave clock may correlate received signals with a representation of the expected synchronization signal to produce a correlation sample sequence at a first sample rate which is related as n times the slave clock rate. The synchronization signal receipt time indicated by the correlation sample sequence may be refined by interpolating the correlation sample sequence around a best correlation sample to locate a best interpolation at an interpolation resolution smaller than the sample resolution. The best interpolation may in turn be further refined by estimating between interpolator outputs adjacent to the best interpolation output. The synchronization signal receipt time thus determined is compared to the expected time based upon the slave clock, which is adjusted until the times match. After initialization, all slave clock errors are preferably accumulated to prevent long-term slip between the slave and master clocks. Formerly independent master and slave clocks synchronized across the communication link constitute a noncommon clock which may be compared on each side of the link to secondary independent clocks, and the secondary independent clocks may then be separately synchronized by adjusting one to have the same difference from its local noncommon clock as the secondary clock on the other side of the link has from its local noncommon clock. | 11-12-2009 |

| 20120097796 | Satellite orbit raising using electric propulsion - Apparatus and methods for raising the orbit of a satellite having electric propulsion thrusters, an Earth sensor and an inertial reference sensor such as a gyro. A satellite positioning system generates orbital data and a profile generator generates an ideal electric orbit raising profile of the satellite. The ideal profile is one that the satellite must follow so that the perigee, apogee and inclination of the satellite can be adjusted simultaneously in a mass-efficient manner. A state machine processes the ideal profile and a true anomaly to generate a desired electric orbit raising profile. Steering apparatus generates signals that are used to control the attitude of the satellite to follow the desired profile. The desired profile places the satellite in an Earth-pointed attitude when the satellite is at a predefined point in the orbit, slews the satellite from the Earth-pointed attitude to an ideal orbit raising attitude, steers the satellite according to the ideal profile during orbit raising, and steers the satellite from the desired attitude to the Earth-pointed attitude. | 04-26-2012 |
