METHOD AND APPARATUS FOR DETERMINING THE QUALITY OF OPTICAL DISK READ SIGNAL |
摘要 |
The invention provides a method and apparatus l,for determining the quality of the optical disk read signal. Said method comprises: comparing said optical disk read signal with a preset reference signal to acquire the signal values correlated with said preset reference signal in said optical disk read signal, with said correlated signal values satisfying a preset condition; sampling said optical disk read signal to acquire a, plurality of sampled signal values; acquiring, with respect to each of said signal values, two sampled signal values that are adjacent to each of said signal values according to said signal values and said sampled signal values; and finally determining the quality of said optical disk read signal on the basis of the preset relationship between the average and the maximum values of the differences of said two adjacent sampled signal values that are corresponding to each of the signal values. |
