Title: (EN) Method and apparatus for motion compensation prediction
(ZH) 用于运动补偿的视频解码方法和视频解码器
Abstract: front page image
(EN) The invention relates to a motion compensation performed under an inter-frame prediction. A fractional sample interpolation is applied on retrieved samples to generate fractional samples. The fractional sample interpolation comprises a plurality of filtering operations, and all of filtered results from the filtering operations are truncated down to a predetermined bit depth independent of the bit depth of the samples stored in the reference picture memory.
(ZH) 视频解码方法和视频解码器。视频解码方法包括计算机可执行步骤,由视频解码器的处理器执行,以实现:从基准图片存储器检索基准样本;在第一方向上对检索出的样本应用第一分数样本插值,以生成第一组分数样本;在第二方向上对第一组分数样本应用第二分数样本插值,以生成第二组分数样本,基准样本利用第一比特深度表示并被按比例放大至第二比特深度,第二比特深度对于基准样本恒定,通过样本插值生成一个第二组分数样本和另一个第二组分数样本,判断是否需要进行双向平均处理,判断为需进行该双向平均处理时将这两个第二组分数样本组合来取得双向预测样本,两个第二组分数样本彼此不同,双向预测样本的值被截取以利用基准样本的第一比特深度来表示。
