  • Patent number: 10469869
    Abstract: Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. In some examples, an apparatus includes processing circuitry for video decoding. The processing circuitry decodes prediction information for a first block in a current picture from a coded video bitstream. The prediction information is indicative of an inter prediction mode that determines a first motion vector for the first block from a motion vector predictor. The processing circuitry then constructs, in responses to the inter prediction mode, a candidate list of candidate motion vector predictors with an exclusion from a second block that requires an operation to finalize a second motion vector for the second block in a motion vector derivation. Then, the processing circuitry determines, based on the candidate list, the first motion vector for the first block, and reconstructs the first block according to the first motion vector for the first block.
