20130225773 | CATALYST COMPONENT FOR OLEFIN POLYMERIZATION REACTION AND CATALYST THEREOF - A catalyst component for olefin polymerization which contains magnesium, titanium, halogen and electron donors is provided in the present invention. The electron donors are selected from at least one succinate compounds of following general formula (I), and the content of said succinate compounds with the structure as shown in Formula (II) in said succinate compounds (I) is less than 100%, but not less than 51.0 wt %. Compared with the mesomer whose content with the structure as shown in Formula (II) is 100%, the catalyst component provided by the present invention not only greatly decreases the manufacturing cost, but also improves certain properties of the catalyst, for example the molecular weight distribution of polymer obtained by catalytic reaction using said catalyst is wider, which is beneficial for improving processing properties of polymers. The corresponding catalyst is also provided. | 08-29-2013 |

20140098189 | PREDICTION PARAMETER INHERITANCE FOR 3D VIDEO CODING - A three-dimensional (3D) video codec encodes multiple views of a 3D video, each including texture and depth components. The encoders of the codec encode video blocks of their respective views based on a set of prediction parameters, such as quad-tree split flags, prediction modes, partition sizes, motion fields, inter directions, reference indices, luma intra modes, and chroma intra modes. The prediction parameters may be inherited across different views and different ones of the texture and depth components. | 04-10-2014 |

20140286408 | INTER-LAYER PIXEL SAMPLE PREDICTION - Systems, devices and methods are described including performing scalable video coding using inter-layer pixel sample prediction. Inter-layer pixel sample prediction in an enhancement layer coding unit, prediction unit, or transform unit may use reconstructed pixel samples obtained from a base layer or from a lower enhancement layer. The pixel samples may be subjected to upsample filtering and/or refinement filtering. The upsample or refinement filter coefficients may be predetermined or may be adaptively determined. | 09-25-2014 |
20140286409 | ENHANCED REFERENCE REGION UTILIZATION FOR SCALABLE VIDEO CODING - Techniques to identify one or more candidate reference blocks used to generate a prediction block to encode a current coding block. The candidate reference blocks can be in the same layer as the current coding block or a different layer. In addition, the candidate reference blocks do not have to be co-located with the current coding block. Motion vectors and shift vectors can be used to identify the one or more candidate reference blocks. In addition, uniform and non-uniform weighting can be applied to the one or more candidate reference blocks to generate the prediction block. Accordingly, an encoder can determine and identify reference blocks to a decoder that can provide desirable rate-distortion cost. | 09-25-2014 |
