    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.

    摘要: A method and apparatus for encoding and decoding depth lookup table (DLT) using a constrained table value range are disclosed. For a decoder, a constrained table value range from a minimum table value to a maximum table value of the DLT is decoded from the coded DLT information. Bit map values for depth values in a depth range from (the minimum table value+1) to (the maximum table value−1) are then decoded. The bit map values indicate whether the depth values are in the DLT respectively. The DLT for the current depth map can be reconstructed based on the constrained table value range and the bit map values for the depth values in the depth range. For an encoder, a constrained table value range from a minimum table value to a maximum table value of the DLT is determined and encoded the DLT into coded DLT information.

    摘要: A method and apparatus for three-dimensional and multi-view video coding are disclosed, where the motion vector (MV) or disparity vector (DV) candidate list construction process for a block depends on whether the target reference picture corresponds to an inter-view reference picture or whether the inter-view candidate refers to an inter-view reference picture. In one embodiment, an MV or DV candidate list for a block coded in Merge mode is constructed, and an inter-view candidate in the MV or DV candidate list is set lower than the first candidate position if the inter-view candidate refers to an inter-view reference picture. In another embodiment, an MV or DV candidate list for a block coded in advanced motion vector prediction mode is constructed, and an inter-view candidate is set lower than the first candidate position if the inter-view candidate refers to an inter-view reference picture.
