VIDEO ENCODING AND DECODING METHOD AND DEVICE USING SAID METHOD |
摘要 |
The present invention minimizes the clipping of a pixel value in upsampling and interpolation filter processes in reference to a restoration image of a reference layer by an enhancement layer in an SVC decoder and thus minimizes a decrease in picture quality. Also, by adjusting and limiting the motion vector of the enhancement layer to the position of an integer pixel when deriving a differential coefficient of the reference layer by using a motion vector of the enhancement layer in the GRP process, it is possible to create a differential coefficient without performing additional interpolation on the image of the reference layer. |
