摘要

The present invention provides a method for encoding, a method for decoding, an apparatus for encoding and an apparatus for decoding a video signal. The video signal at the encoder is first transformed into the frequency domain. Based on a video signal in the frequency domain, filter data are determined to be used for filtering in the frequency domain. The filter data are then provided to a decoder side. A decoder in accordance with the present invention is capable of obtaining such filter data for filtering in frequency domain from the encoder side, based thereon setting-up a filter to be applied in the frequency domain, and filtering a video signal by the filter.
