    • 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.
    • 自适应可变长度编码技术可以用于由预测性视频编码产生的残差块系数的熵编码。 这些技术可以应用于使用零运行来编码非零变换系数的位置的方案。 可以将诸如块结束(EOB)移位和VLC码本选择表的编码参数保持为内部状态,而不是用编码的视频片段数据发送它们。 可以基于在编码过程期间收集的统计信息周期性地更新表格条目。 特殊的EOB移位表可以将符号集合中的特殊EOB符号的位置适应于诸如编码周期的编码条件的幅度大于1的有效系数的概率。 色度块可以使用独立的EOB移位,特殊EOB移位和VLC码本选择表独立于亮度块进行编码。

    • 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.

    • 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.
    • 本公开涉及使用广义细粒度可伸缩性(FGS)方法来支持空间可伸缩性的视频编码技术。 可以通过以广义的FGS格式发送空间可缩放的增强层来实现不同程度的空间可伸缩性。 空间可缩放的增强比特流可以被任意地截断以符合网络条件,信道条件和/或解码器能力。 用于空间可扩展性的编码系数和语法元素可以嵌入广义的FGS格式。 对于良好的网络或信道条件和/或增强的解码器能力,经由一个或多个增强层接收到的附加比特允许以增加的空间分辨率重建经过编码的视频并且跨越不同的空间分辨率连续改善视频质量。 这些技术允许空间可扩展性层被编码为FGS层,而不是离散层,允许任意的可扩展性。 这些技术可以包括抑制由于部分解码而可能出现的误差传播的特征。

    • 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.

In this manner, the techniques of this disclosure may allow a video content viewer the ability to choose a ROI to watch.

    • A capping layer may be deposited over the active channel of a thin film transistor (TFT) in order to protect the active channel from contamination. The capping layer may affect the performance of the TFT. If the capping layer contains too much hydrogen, nitrogen, or oxygen, the threshold voltage, sub threshold slope, and mobility of the TFT may be negatively impacted. By controlling the ratio of the flow rates of the nitrogen, oxygen, and hydrogen containing gases, the performance of the TFT may be optimized. Additionally, the power density, capping layer deposition pressure, and the temperature may also be controlled to optimize the TFT performance.
