Abstract: To encode a coding unit in the inter modes, there exist multiple inter modes that signal the motion information using a Motion Vector Predictor (MW) list. The MW lists for different coding modes include spatial predictors. In one embodiment, for all coding modes that use MVP lists, the top spatial predictor is first added to the motion vector predictor list before the left spatial predictor. In another embodiment, a subset of coding modes adds the top spatial predictor before the left spatial predictor, and another subset of coding modes adds the left spatial predictor before the top spatial predictor. For example, all merge modes add the top spatial predictor first, and all AMVP modes add the left spatial predictor first. In another example, all non-sub-block modes add the top spatial predictor first, and all sub-block modes add the left spatial predictor first.

Abstract: The invention relates to a method for determining a set-point voltage for a piezoelectric actuator system to achieve a desired optical response of the piezoelectric actuator system, such as an optical power. The method is based on a mathematical model, OP(V,T,n) describing a relationship between the applied voltage and the optical response. Calibration and use of the model involves determining a transition time count value. During use, e.g. at given intervals, the model is updated based on actual values of the temperature and the transition time count value. The set-point voltage required to achieve a desired optical response is determined based on the updated model and the set-point voltage is applied to the piezoelectric actuator.

Abstract: A video encoder or decoder processes portions of video using virtual temporal affine motion candidates. Under the general aspects, virtual temporal affine candidates are created using only the classical temporal motion buffer information, avoiding the storage of additional affine parameters in a temporal motion buffer. A motion field for encoding or decoding a video block is generated based on the virtual temporal affine candidates. In one embodiment, collocated motion candidates are rescaled by adjusting the picture order count of the determined motion field. In another embodiment, resolution adaptation is performed to enable a current motion buffer to correspond to a reference motion buffer.
