摘要：
A video decoder and a video encoder include a noise reduction operation including at least two denoising operations and adapting the second denoising operation in dependence of the difference before and after the first denoising operation, thus correcting the quality reduction occurred due to the application of the first denoising operation. Corresponding methods serve to encode and decode video signals.
