<p>Disclosed are a device and a method for transforming first coding coefficients of video signals into second coding coefficients of the video signals. The device includes a first storing unit for storing the first coding coefficients; a second storing unit for storing a transform matrix; a multiplication unit for multiplying the first coding coefficients by coefficients of the transform matrix; an addition unit for adding each of values resulted from the multiplication operation of the multiplication means to form a sum; and a shifting unit for shifting the sum to obtain the second coding coefficients. According to the present invention, signals compressed by various transforms may be transformed to each other, so as to make various compression signals compatible. Thus, the signals can be compatible with more standards and are more universal.</p> |
