    • The present invention relates to a method for increasing video compression efficiency in a video encoder that uses conversion in a block unit. The invention provides a compressive encoding apparatus and method which can increase compression efficiency without influencing the picture equality by reducing data to be compressed. Thus, the method comprises the steps of: configuring a filter which importantly sets DC data and filter coefficients around the DC data by considering that data conversion sensitively works on the eyes of a person when closer to a low frequency and insensitively works on the eyes of a person when closer to a high frequency, if data is converted into frequency components during the data conversion; calculating a cost which is necessary for removing the compressed and encoded data relative to a conversion block that has passed through conversion and quantization by using the filter; determining the data removal relative to a set basic block by using reference values which are set for the calculated cost; and determining the data removal relative to a macro block in which the corresponding basic block is included, thereby removing data for the determined block.
    • 本发明涉及一种用于在使用块单元中的转换的视频编码器中提高视频压缩效率的方法。 本发明提供了一种压缩编码设备和方法,它可以通过减少要被压缩的数据来提高压缩效率而不影响图像相等。 因此,该方法包括以下步骤:配置滤波器,该滤波器通过考虑数据转换灵敏地在人的眼睛上工作,当接近低频并且不敏感地在眼睛上工作时重要地设置DC数据周围的DC数据和滤波器系数 如果数据在数据转换期间转换为频率分量,则更接近高频; 相对于通过使用滤波器已经通过转换和量化的转换块,计算去除压缩和编码数据所需的成本; 通过使用为所计算的成本设置的参考值来确定相对于设置的基本块的数据移除; 以及确定相对于其中包括相应的基本块的宏块的数据移除,从而移除针对所确定的块的数据。
