    • Encoders and methods of encoding that incorporate deblocking into the encoding process. An encoder performs a two-cycle encoding process. First, an original block is processed and then reconstructed and deblocked. The reconstruction and the deblocked reconstruction are compared to the original and an intermediate block is created that contains the portions of the reconstruction or the deblocked reconstruction that are more similar to the original. In the second cycle, the intermediate block serves to generate a modified original block, which is then used in a prediction process to create a new prediction block. The new prediction block as compared to the original gives new residuals. The new prediction and new residuals are entropy coded to generate the encoded video data. The new prediction block and new residuals incorporate the deblocking elements selectively identified during the first cycle, thereby eliminating the need for deblocking at the decoder. The prediction operation may be motion prediction or spatial prediction.
    • 编码器和编码方法,将解封装入编码过程。 编码器执行两周期编码处理。 首先,处理原始块,然后重建和解块。 将重建和解块重构与原始的重建进行比较,创建一个包含与原来更接近的重构或解块重构的部分的中间块。 在第二周期中,中间块用于产生经修改的原始块,然后将其用于预测过程以创建新的预测块。 与原来相比,新的预测块产生了新的残差。 新的预测和新的残差被熵编码以产生编码的视频数据。 新的预测块和新的残差包括在第一周期期间选择性地识别的去块元件,从而消除了在解码器处的解块的需要。 预测操作可以是运动预测或空间预测。
