A key point in Short Time Fourier Transform is the choice of window function. Although rectangle window is regarded as the first choice because it's featured by integral harmonic to filter signals and by DC component, decaying DC component and frequency shift of signals cause great error to rectangle window STFT. In addition, transient signals contain rich information of faults, but the fixed time window of STFT fail to collect these information.

STFT 算法关键问题之一是窗函数的选择，矩形窗以滤除信号整数次谐波和直流分量的特点自然称为首选窗，但衰减直流分量和信号的频率偏移对矩形窗 STFT 造成了很大误差；其次，暂态信号中含有丰富的故障信息，傅立叶变换固定的频窗忽略了这些特征信息。

The process is characterized in that, the zoomed image being defined by its horizontal and vertical homothety ratio with respect to the coded image (1, 7), it performs the following steps: calculation of the horizontal and vertical sizes of an initial display rectangle (8) from which would be obtained the sizes of the target display rectangle (2) as defined by the profile and level information by applying the horizontal and vertical homothety ratios, storage in the display_horizontal_size and display_vertical_size fields of an MPEG2 video data stream of the horizontal and vertical sizes of the initial display rectangle.

该方法的特点是被缩放图像由它针对被编码图像(1，7)的水平和垂直缩放率定义，它执行下面的步骤：通过应用水平和垂直缩放率来计算初始显示长方形(8)的水平和垂直尺寸，从中可以获得按照轮廓和级别信息定义的目标显示长方形(2)的尺寸，在MPEG2视频数据流的display_horizontal_size和display_vertical_size字段中存储初始显示长方形的水平和垂直尺寸。
