Abstract: PURPOSE: A de-blocking method for a prediction block and a device thereof are provided to increase the efficiency of an encoding or decoding process by determining a boundary filtering strength when a skip encoding mode is applied to a boundary block. CONSTITUTION: When one or more encoded blocks exist in a block p and a block q, a de-blocking device determines a boundary filtering strength as 0 (S800, S810). When one or more intra-encoded blocks exist in the block p and the block q, the device determines the matching state between the boundary of the block p and the block q and the boundary of macro block (S820, S830). The device determines the boundary filtering strength according to the determination result (S840, S890).
Abstract translation: 目的：提供一种用于预测块及其装置的解块方法，用于通过在将跳过编码模式应用于边界块时确定边界滤波强度来提高编码或解码过程的效率。 构成：当在块p和块q中存在一个或多个编码块时，解块装置将边界滤波强度确定为0（S800，S810）。 当在块p和块q中存在一个或多个帧内编码块时，装置确定块p的边界与块q和宏块的边界之间的匹配状态（S820，S830）。 设备根据确定结果确定边界过滤强度（S840，S890）。
