Abstract:

An apparatus for processing a substrate, comprising a processing chamber and a substrate support and lift pin assembly disposed within the chamber. The substrate support and lift pin assembly are coupled to a lift mechanism that controls positioning of the substrate support and the lift pins and provides rotation for the substrate support. The lift mechanism includes at least one sensor capable of generating a signal when clearance between the substrate support and the lift pins allows rotation of the substrate support to begin. The substrate support capable of concurrent axial motion and rotation may be used in a processing chamber comprising multiple processing zones separated by edge rings. Substrates may be subjected to successive or cyclical processes by moving between the multiple processing zones.

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:

A method for intra prediction mode decoding for a current block based on multi-level most probable mode (MPM) sets. The method includes determining one or more MPM candidates for a first-level MPM set, and determining one or more most probable remaining mode (MPRM) candidates for a second-level MPM set. Wherein the one or more MPRM candidates are identified based on a mode of a neighboring block of the current block, and the one or more MPRM candidates are different from any MPM candidate in the first-level MPM set. The method also includes decoding syntax information related to a current intra prediction mode corresponding to the current block according to the multi-level MPM sets using a decoder, and decoding the current block based on the determined current intra prediction mode.

Abstract:

A method for chroma intra prediction mode decoding includes decoding a chroma intra prediction mode for a current chroma block according to a codeword set corresponding to a chroma intra prediction mode set, wherein the codeword set comprises at least one codeword with a first length type and at least one codeword with a second length type. If a codeword is one of said at least one codeword with the first length type, the chroma intra prediction mode is decoded as a Luma-based chroma prediction Mode (LM) or a Direct Mode (DM). The method also includes determines the chroma intra prediction mode based on an intra prediction mode of a current luma block if the chroma intra prediction mode is the DM.

Abstract:

Embodiments according to the present invention configure the intra prediction mode candidates into multi-level MPM sets, which comprise at least a first-level MPM set and a second-level MPM set. Encoding or decoding a current intra prediction mode is based on the multi-level MPM sets, where one syntax element of the syntax information to be generated or decoded respectively is associated with evaluating the current intra prediction mode using the first-level MPM set. A method and apparatus for spectively is associated with evaluating the current intra prediction mode using the first-level MPM set. A method and apparatus for chroma intra prediction mode encoding and decoding are also disclosed. The chroma intra prediction mode set includes a Luma-based chroma prediction Mode (LM), a Direct Mode (DM) and four other modes. The codeword set comprises variable-length codewords and fixed-length codewords, and the fixed-length codewords are longer than the variable-length codewords. The variable-length codewords are used for the DM and LM, and the fixed-length codewords are used for the four other modes.
