    摘要: This disclosure describes techniques for coding of header information of video blocks. In particular, the techniques of this disclosure select one of a plurality of prediction modes for use in generating a prediction block of a video block of a coding unit, the plurality of prediction modes including unidirectional prediction modes and multi-directional prediction modes that combine at least two unidirectional prediction modes. An encoding device encodes the prediction mode of the current video block based on prediction modes of one or more previously encoded video blocks of the coding unit. Likewise, a decoding unit receives encoded video data of a video block of a coding unit and decodes the encoded video data to identify one of a plurality of prediction modes for use in generating a prediction block of the video block based on prediction modes of one or more previously decoded video blocks of the coding unit.

    摘要: In a video processing system, a method and system for applying transforms larger than 8×8 and non-rectangular transforms, and generating transform size syntax elements indicative of the transforms for video decoding are provided. The transform size syntax element may be generated by an encoder based on a prediction block size of a video block and the contents of the video block. Further, the transform size syntax element may be generated according to a set of rules to select from 4×4, 8×8, and larger transform sizes during an encoding process. A decoder may perform an inverse transform based on the transform size syntax element and the rules used by the encoder. The transform size syntax element may be transmitted to the decoder as part of the encoded video bitstream.

    摘要: Adaptive variable length coding techniques may be used for entropy coding of residual block coefficients produced by predictive video coding. The techniques may be applied to schemes that code positions of nonzero transform coefficients using zero runs. Coding parameters such as end of block (EOB) shift and VLC codebook selection tables may be maintained as internal states, instead of sending them with coded video slice data. Table entries may be periodically updated based on statistics collected during a coding pass. A special EOB shift table may adapt the position of a special EOB symbol in a symbol set to probability of significant coefficients with magnitude greater than one for a coding condition, such as a coding cycle. Chroma blocks may be coded independently of luma blocks using separate EOB shift, special EOB shift, and VLC codebook selection tables.

    摘要: Embodiments disclosed herein generally relate to TFTs and methods of fabricating the TFTs. In TFTs, the active channel carries the current between the source and drain electrodes. By tailoring the composition of the active channel, the current can be controlled. The active channel may be divided into three layers, a gate control layer, a bulk layer, and an interface control layer. The separate layers may have different compositions. Each of the gate control, bulk and interface control layers may additionally comprise multiple layers that may have different compositions. The composition of the various layers of the active channel comprise oxygen, nitrogen, and one or more elements selected from the group consisting of zinc, indium, cadmium, tin, gallium and combinations thereof. By varying the composition among the layers, the mobility, carrier concentration and conductivity of the various layers may be controlled to produce a TFT having desired properties.

    摘要: The disclosure is directed to video coding techniques that support spatial scalability using a generalized fine granularity scalability (FGS) approach. Various degrees of spatial scalability can be achieved by sending spatially scalable enhancement layers in a generalized FGS format. Spatially scalable enhancement bitstreams can be arbitrarily truncated to conform to network conditions, channel conditions and/or decoder capabilities. Coding coefficients and syntax elements for spatial scalability can be embedded in a generalized FGS format. For good network or channel conditions, and/or enhanced decoder capabilities, additional bits received via one or more enhancement layers permit encoded video to be reconstructed with increased spatial resolution and continuously improved video quality across different spatial resolutions. The techniques permit spatial scalability layers to be coded as FGS layers, rather than discrete layers, permitting arbitrary scalability. The techniques may include features to curb error propagation that may otherwise arise due to partial decoding.

    摘要: The present invention generally relates to thin film transistors (TFTs) and methods of making TFTs. The active channel of the TFT may comprise one or more metals selected from the group consisting of zinc, gallium, tin, indium, and cadmium. The active channel may also comprise nitrogen and oxygen. To protect the active channel during source-drain electrode patterning, an etch stop layer may be deposited over the active layer. The etch stop layer prevents the active channel from being exposed to the plasma used to define the source and drain electrodes. The etch stop layer and the source and drain electrodes may be used as a mask when wet etching the active material layer that is used for the active channel.

    摘要: Embodiments disclosed herein generally relate to a method for seasoning a sputtering target in-situ with a substrate to be processed. New semiconductor compounds containing oxygen, nitrogen, and an element such as zinc, cadmium, tin, indium, and gallium are beginning to replace silicon as the material for active channels in TFTs. The new semiconductor compounds may be deposited by a reactive sputtering process. During the sputtering process, reactive gas reacts with the metal from the sputtering target and deposits on the substrate. Some of the reactive gas may react at the surface and lead to a buildup of a compound at the target surface. Because oxygen and nitrogen are quite reactive, an oxide or nitride compound may develop at the target surface. The oxide or nitride may be removed by seasoning the sputtering target. The seasoning may occur while the substrate is within the processing chamber.

    摘要: This disclosure describes techniques for region-of-interest (ROI) encoding. In accordance with the techniques described herein, an encoding device may determine a temporal spatial dependency value for a candidate reference video block for inter-coding a current block in a video frame. The encoding device may compare the temporal spatial dependency value to a threshold value and select a coding mode for the current block based on the comparison. A decoding device may receive data defining a ROI as well as the temporal spatial dependency value and decode a video block in the ROI based at least in part on the temporal spatial dependency value. In this manner, the techniques of this disclosure may allow a video content viewer the ability to choose a ROI to watch.
