Abstract
A method of decoding a video signal, apparatus, and a non-transitory computer-readable storage medium are provided. The method includes obtaining a video block from the video signal, obtaining spatial neighboring blocks based on the video block, obtaining up to one left non-scaled motion vector predictor (MVP) based on the multiple left spatial neighboring blocks, obtaining up to one above non-scaled MVP based on the multiple above spatial neighboring blocks, deriving, at the decoder and by reducing possibility of selecting scaled MVPs derived from the spatial neighboring blocks, an MVP candidate list based on the video block, the multiple left spatial neighboring blocks, the multiple above spatial neighboring blocks, receiving a best MVP based on the MVP candidate list, and obtaining a prediction signal of the video block based on the best MVP.
