摘要： A method and apparatus for video coding including an Intra transform Skip mode is disclosed. When the transform Skip mode is ON for a transform unit, embodiments according to the present invention apply different coding processes to the transform unit. The coding process with the transform Skip mode ON uses a different scan pattern from the coding process with the transform Skip mode OFF. According to various embodiments, the transform Skip mode is enabled when the transform unit size is 4x4, the prediction unit and the transform unit having the same size, or the prediction unit uses an INTRA_NxN mode. When the transform Skip mode is enabled, a flag can be signaled in the bitstream to indicate the transform Skip mode selection. Furthermore, the flag can be incorporated in a picture level, a slice level or a sequence level of the video bitstream.

摘要： The intra transform skip mode in HEVC is restrictedly enabled only when Prediction Unit (PU) is equal to Transform Unit (TU), which reduces the encoding complexity and saves the signaling bits for transform skip flag. The scan order is inversed for intra transform skip mode to adapt the different energy distribution for transform off case, which is easy to implement and coding performance is improved.

摘要： A method and apparatus for deriving a motion vector predictor (MVP) candidate set for motion vector coding of a current block. Embodiments according to the present invention determine a redundancy-removed spatial MVP candidate set by removing any redundant MVP candidate from the spatial MVP candidate set. The redundancy-removal process does not apply to the temporal MVP candidate. In another embodiment of the present invention, a redundancy-removed spatial-temporal MVP candidate set is determined and the number of candidates in the redundancy-removed spatial-temporal MVP candidate set is checked to determine whether it is smaller than a threshold. If the number of candidates is smaller than the threshold, a zero motion vector is added to the redundancy-removed spatial-temporal MVP candidate set. The redundancy-removed spatial-temporal MVP candidate set is then provided for encoding or decoding of the motion vector of the current block.

摘要： Apparatus and methods for autonomously controlling fluid flow in a subterranean well are presented, and in particular for providing a fluid diode to create a relatively high resistance to fluid flow in one direction and a relatively low resistance to fluid flowing in the opposite direction. The diode is positioned in a fluid passageway and has opposing high resistance and low resistance entries. In one embodiment, the high resistance entry has a concave, annular surface surrounding an orifice and the low resistance entry has a substantially conical surface. The concave, annular surface of the high resistance entry preferably extends longitudinally beyond the plane of the orifice. In a preferred embodiment, the fluid will flow in eddies adjacent the concave, annular surface.

摘要： An apparatus and method are described for autonomously controlling flow of fluid in a subterranean well, where fluid flow is controlled based on a fluid characteristic, such as viscosity or density, which changes over time. Fluid flows into a vortex assembly where a centrifugal force is imparted to the fluid. A less viscous fluid will have a relatively greater velocity and centrifugal force than a more viscous fluid. The fluid exits the vortex chamber by both a vortex outlet and a peripheral outlet. An autonomous valve element moves between an open position, in which fluid flows freely through the peripheral outlet, and a closed position, in which fluid flow through the peripheral outlet is restricted. The valve element is moved by the centrifugal force of the fluid, such that a fluid having a higher centrifugal force moves the valve element to the closed position, thereby reducing the total fluid flow through the vortex assembly.
摘要翻译：描述了一种用于自主控制地下井中的流体流动的装置和方法，其中基于随时间变化的流体特性（例如粘度或密度）来控制流体流动。流体流入涡流组件，其中离心力被施加到流体。较粘稠的流体将具有比较粘稠的流体相对更大的速度和离心力。流体通过涡流出口和外围出口都离开涡流室。自主阀元件在流体通过周边出口自由流动的打开位置和闭合位置之间移动，在该位置中流过外围出口的流体受到限制。阀元件通过流体的离心力移动，使得具有较高离心力的流体将阀元件移动到关闭位置，从而减少通过涡流组件的总流体流量。

摘要： A method and apparatus for selecting an intra interpolation filter for multi-line intra prediction based on a reference line index for decoding a video sequence includes identifying a set of reference lines associated with a coding unit. A first type of interpolation filter is applied to reference samples included in a first reference line, of the set of reference lines, that is adjacent to the coding unit to generate a first set of prediction samples based on the first reference line being associated with a first reference line index. A second type of interpolation filter is applied to reference samples included in a second reference line, of the set of reference lines, that is non-adjacent to the coding unit to generate a second set of prediction samples based on the second reference line being associated with a second reference line index.

摘要： A method of variably restricting flow in a subterranean well can include resisting the flow through a sidewall of a tubular string, and then selectively opening a device in response to a predetermined pressure signal being transmitted. The opening of the device can substantially reduce a resistance to the flow through the tubular string sidewall. A flow restrictor system for use with a subterranean well can include a flow restrictor which resists flow through system, a pressure sensor, and an initially closed device which opens and thereby permits the flow to bypass the flow restrictor, in response to a predetermined pressure signal being detected by the sensor.
