    Abstract: PURPOSE: A video encoding and decoding apparatus and a method using context information based adaptive post filter are provided to improve the efficiency of video encoding. CONSTITUTION: A reconstitution video generator(120) creates the reconstructed image using the differential signal and the restored prediction frame. The reconstitution video generator applies the deblocking filter. A post filter unit(130) decides whether to apply the fixed post filter based on the contextual information of the reconstructed image to the reconstructed image. The post filter unit decides whether to apply the post filter adaptively based on the contextual information of the reconstructed image to the reconstructed image. The post filter unit applies the fixed post filter or the post filter which was adaptively generated to the reconstructed image.

    Abstract translation: 目的:提供一种使用基于上下文信息的自适应后置滤波器的视频编码和解码装置和方法,以提高视频编码的效率。 构成:重构视频发生器(120)使用差分信号和恢复的预测帧创建重构图像。 重构视频发生器应用去块滤波器。 后置滤波器单元(130)基于重构图像的上下文信息来确定是否将该固定后置滤波器应用于重构图像。 后置滤波器单元基于重构图像的上下文信息自适应地将后置滤波器应用于重构图像。 后置滤波器单元将自适应生成的固定后置滤波器或后置滤波器应用于重建图像。
