    • This disclosure describes filtering techniques applied by an encoder and a decoder during the prediction stage of a video encoding and/or decoding process. The filtering techniques may enhance the accuracy of predictive data used during fractional interpolation, and may improve predictive data of integer blocks of pixels. There are several aspects to this disclosure, including a useful twelve-pixel filter support that may be used for interpolation, techniques that use coefficient symmetry and pixel symmetry to reduce the amount of data needed to be sent between an encoder and a decoder to configure the filter support for interpolation, and techniques for filtering data at integer pixel locations in a manner that is similar to sub-pixel interpolation. Other aspects of this disclosure concern techniques for encoding information in the bitstream to convey the type of filter used, and possibly the filter coefficients used. Predictive coding of filter coefficients is also described.

    • This disclosure describes selective deblock filtering techniques that are particularly useful with coding standards that do not specify in-loop deblock filtering for standard compliance. In accordance with this disclosure, deblock filtering may be selectively performed with respect to block boundaries of a given video block being coded, a motion compensation process can be performed using a filtered version of the prediction video frame used to code the given video block, or both. This disclosure also provides selection rules that can be applied to determine what type of deblocking techniques to apply in various scenarios. The selection rules may improve the video coding and may also ensure that mismatch between video blocks at an encoder and a decoder is not introduced by the deblock filtering.

    • This disclosure recognizes and exploits the fact that some of the filter coefficients defined at the encoder may possess symmetry relative to other filter coefficients. Accordingly, this disclosure describes techniques in which a first set of the filter coefficients are used to predictively encode a second set of the filter coefficients, thereby exploiting any symmetry between filter coefficients. Rather than communicate all of the filter coefficients to the decoding device, the encoding device may communicate the first set of filter coefficients and difference values associated with the second set of filter coefficients. Using this information, the decoder may be able to reconstruct all of the filter coefficients. In some cases, if exact symmetry is imposed, the need to send the difference values may be eliminated and the decoder may be able to derive the second set of filter coefficients from the first set of filter coefficients.
    • 本公开识别和利用了在编码器处定义的一些滤波器系数相对于其它滤波器系数可能具有对称性的事实。 因此,本公开描述了其中使用第一组滤波器系数来预测性地编码第二组滤波器系数的技术,从而利用滤波器​​系数之间的任何对称性。 编码设备不是将所有的滤波器系数传送到解码设备,而是可以传送与第二组滤波器系数相关联的第一组滤波器系数和差值。 使用该信息,解码器可以能够重构所有的滤波器系数。 在一些情况下,如果施加精确的对称性,则可以消除发送差值的需要,并且解码器可以能够从第一组滤波器系数导出第二组滤波器系数。

A prediction of an original video signal in a current frame is constructed from the video sequence. A residual signal is formed by subtracting the prediction of the original video signal from the original video signal in the current frame. A transform is applied to the residual signal. A plurality of transform coefficients is quantized. A refinement coefficient is mapped to a ternary refinement symbol. Refinement symbols are grouped in a certain coding order.

    • The present invention generally comprises TFTs having semiconductor material comprising oxygen, nitrogen, and one or more element selected from the group consisting of zinc, tin, gallium, cadmium, and indium as the active channel. The semiconductor material may be used in bottom gate TFTs, top gate TFTs, and other types of TFTs. The TFTs may be patterned by etching to create both the channel and the metal electrodes. Then, the source-drain electrodes may be defined by dry etching using the semiconductor material as an etch stop layer. The active layer carrier concentration, mobility, and interface with other layers of the TFT can be tuned to predetermined values. The tuning may be accomplished by changing the nitrogen containing gas to oxygen containing gas flow ratio, annealing and/or plasma treating the deposited semiconductor film, or changing the concentration of aluminum doping.

    • The present invention generally relates to an offset electrode TFT and a method of its manufacture. The offset electrode TFT is a TFT in which one electrode, either the source or the drain, surrounds the other electrode. The gate electrode continues to be below both the source and the drain electrodes. By redesigning the TFT, less voltage is necessary to transfer the voltage from the source to the drain electrode as compared to traditional bottom gate TFTs or top gate TFTs. The offset electrode TFT structure is applicable not only to silicon based TFTs, but also to transparent TFTs that include metal oxides such as zinc oxide or IGZO and metal oxynitrides such as ZnON.
