    摘要： The present invention relates to a method of channel estimation comprising two major steps. The first step is the least-squared and minimum mean-square error (MMSE) estimations on the pilot resource elements to generate the channel response estimates at the predefined pilot locations. The second step of the channel estimation, which utilizes the results from the first step to compute the channel response estimates for the remaining resource elements, comprises the following three operations: (i) averaging of each pair of adjacent pilot resource elements in the frequency direction to obtain the channel response estimate of the resource element in the middle of those two pilot resource elements; (ii) MMSE interpolation in the time domain for all the sub-carriers containing pilot signals; and (iii) linear interpolation in the frequency direction for all the sub-carriers not containing any pilot signals.

    摘要： A method and apparatus for adaptive de-blocking filter are disclosed. One or more parameters associated with a de-blocking filter are determined. De-blocking filter using the derived parameters are then applied to reconstructed blocks. Each set of parameters is used for each picture, slice, coding tree unit (CTU) or CU (coding unit). The parameters can be signalled in VPS (video parameter set), SPS (sequence parameter set), PPS (picture parameter set), slice header, CTU (coding tree unit) or CU (coding unit) of the video bitstream. The parameters correspond to one or more values used as thresholds, clipping boundaries, or both the thresholds and clipping boundaries for the de-blocking filter. In one embodiment, the parameters for the current picture are determined using a training process using a current coded picture a previous coded picture as training data.

    摘要： Improvements in a bracket is disclosed for mounting an electrical box onto a mounting bar. An electrical box can be preinstalled onto the bracket and clamped onto the mounting bar using wings. Bendable tabs can be articulated to secure the bracket and onto a rail. Fasteners are used to secure an electrical junction box onto the bracket and an additional fastener secures the sub assembly to the rail. The tabs can be unbent for removal. An installer can secure the bracket and electrical box using a screw and adjust the position of the bracket on the mounting bar. The bracket provides a low profile assemble that allows the bracket to be installed between the inner surfaces of stud walls.

    摘要： Improvements in a conduit locking connector that connects rigid conduit to an electrical junction box. Rigid conduit provides the benefit of allowing an installer to screw onto the side of the rigid conduit to frictionally lock into the rigid conduit with the conduit locking connector. A screw engages into rigid conduit that provide a hard bearing surface on opposing sides of the screw. This provides minimal bending of the rigid conduit for a firmer grip of the rigid conduit to the conduit locking connector. The conduit locking connector provides a physical interface that locks onto the rigid conduit and locks onto the junction box. The conduit locking connector provides anti-rotation between the rigid conduit and the junction box. Anti-rotation is with tabs that extend below a planar surface of the conduit locking connector and engage into holes in recesses in the junction box.

    摘要： A method of illumination compensation for three-dimensional or multi-view encoding and decoding. The method incorporates an illumination compensation flag only if the illumination compensation is enabled and the current coding unit is processed by one 2N×2N prediction unit. The illumination compensation is applied to the current coding unit according to the illumination compensation flag. The illumination compensation flag is incorporated when the current coding unit is coded in Merge mode without checking whether a current reference picture is an inter-view reference picture.
