Abstract: In HEVC (High Efficiency Video Coding), a 2N×2N coding unit can be partitioned into various partition types hierarchically. The coding system uses a criterion to determine the best partition, where RD-rate is often used as the criterion. N×N partition at level k becomes redundant if 2N×2N at level k+1 will be evaluated. In order to eliminate the above redundancy, the allowable partition sizes are constrained according to a method previously disclosed. In the current invention, the complexity is further reduced. According to one embodiment, N×N partition is not allowed for any INTER mode regardless of the coding unit size. Furthermore, flexibility is provided so that either the method and apparatus with further complexity reduction can be selected or an alternative method and apparatus can be selected. Syntaxes to support embodiments according to the present invention are also disclosed.

Abstract: Three block concepts are introduced in HEVC: coding unit (CU), prediction unit (PU), and transform unit (TU). The overall coding structure is characterized by the various sizes of CU, PU and TU in a recursive fashion. For transform processing in current HEVC, a hierarchy RQT (Residual Quad Tree) is used and the TU size is related to the CU size, but independent of the PU size. This results in high encoding complexity and also causes increased processing time to process the syntax of residual quad tree. Accordingly a modified transform unit partition with reduced complexity is disclosed. According to an embodiment, the TU size may be restricted to the minimum of PU width and height, except for a 2N×2N coding unit with the 2N×2N partition type. In another embodiment, the maximum TU size equals to maximum of PU width and height, and the minimum TU size equals to minimum of the PU width and height, except for a 2N×2N coding unit with the 2N×2N partition type. In yet another embodiment, the TU size is selected between 2N×2N and N×N for the 2N×2N, 2N×N, N×2N and N×N partition types. The syntax element, split_transform_flag, is used to indicate the selection of 2N×2N or N×N TU size when needed. Furthermore, a method with reduced complexity of selecting the best merge candidate for the 2N×2N CU merge mode is disclosed. The method relies on R-D cost associated with the motion vector of merge candidate to reduce required computation.

Abstract translation: 在HEVC中引入了三个块概念：编码单元（CU），预测单元（PU）和变换单元（TU）。 总体编码结构的特征在于以递归方式各种尺寸的CU，PU和TU。 对于当前HEVC中的变换处理，使用层次RQT（残余四叉树），并且TU大小与CU大小相关，但与PU大小无关。 这导致高编码复杂度，并且还导致处理剩余四叉树语法的处理时间增加。 因此，公开了具有降低的复杂性的修改的变换单元分区。 根据实施例，除了具有2N×2N分区类型的2N×2N编码单元之外，TU大小可以被限制为PU宽度和高度的最小值。 在另一个实施例中，除了具有2N×2N分区类型的2N×2N编码单元之外，最大TU大小等于PU宽度和高度的最大值，并且最小TU大小等于PU宽度和高度的最小值。 在另一个实施例中，对于2N×2N，2N×N，N×2N和N×N个分区类型，在2N×2N和N×N之间选择TU大小。 语法元素split_transform_flag用于在需要时指示2N×2N或N×N TU大小的选择。 此外，公开了一种选择2N×2N CU合并模式的最佳合并候选的复杂度降低的方法。 该方法依赖于与合并候选的运动矢量相关联的R-D成本来减少所需的计算。

Abstract: Novel trivalent organophosphite ligands having the structure of general formula (I): wherein R is an alkyl or aryl group containing 1 to 30 carbon atoms; Ar1 and Ar2 are aryl groups containing 4 to 30 carbon atoms; R1 to R6 are H or alkyl or aryl hydrocarbon radicals containing 1 to 40 carbon atoms; and X is a connecting group or a simple chemical bond, were developed and found to be very active for hydroformylation processes for ethylenically unsaturated substrates. Catalyst solutions prepared from these ligands with a Rh metal show an unusual “ligand acceleration effect” for simple alkenes, i.e., the hydroformylation activity increases as the concentration of ligand increases, and are capable of producing linear or branched aldehydes under typical hydroformylation conditions.
