    Abstract: A method can include selecting a block of pixels. It may be determined whether the block of pixels contains an edge pixel. If the block of pixels contains an edge pixel, a first pixel may be selected among the block of pixels. If it is determined that the first pixel is a ringing noise pixel, a ringing filter may be applied. An edge-preserved filter may be applied if the first pixel is not a ringing noise pixel.

    Abstract: A method is disclosed for decoding multiple-coded symbols from a coded input symbol stream in a single clock cycle. The method constructs an original Huffman look-up table by extending the associated Huffman tree to decode multiple symbols in one clock cycle in a first embodiment and decodes multiple DCT coefficient symbols in an alternate embodiment. An advantage of the method is that the depth of the new Huffman tree is adjustable thereby making the method easily adaptable to various hardware architectures. A further advantage of the present invention is that the decoding process speed is significantly increased while the size of the lookup table is nominally increased.

    Abstract: Methods and systems to apply motion estimation (ME) based on reconstructed reference pictures in a B frame or in a P frame at a video decoder. For a P frame, projective ME may be performed to obtain a motion vector (MV) for a current input block. In a B frame, both projective ME and mirror ME may be performed to obtain an MV for the current input block. The ME process can be performed on sub-partitions of the input block, which may reduce the prediction error without increasing the amount of MV information in the bitstream. Decoder-side ME can be applied for the prediction of existing inter frame coding modes, and traditional ME or the decoder-side ME can be adaptively selected to predict a coding mode based on a rate distribution optimization (RDO) criterion.

    Abstract translation: 基于在B帧或视频解码器的P帧中的重建参考图像应用运动估计（ME）的方法和系统。 对于P帧，可以执行投影ME以获得当前输入块的运动矢量（MV）。 在B帧中，可以执行投射ME和镜ME两者以获得当前输入块的MV。 可以在输入块的子分区上执行ME处理，这可以在不增加比特流中的MV信息的量的情况下减少预测误差。 解码器端ME可以应用于现有的帧间编码模式的预测，并且传统的ME或解码器侧的ME可以被自适应地选择以基于速率分布优化（RDO）准则来预测编码模式。
