    摘要： A method of encoding video data for blocks (120) of video data is disclosed. The method comprises determining whether to encode a first current block of video data using a first precision motion vector for the first current block or a second precision motion vector for the first current block, wherein the first precision motion vector is a higher precision than the second precision motion vector, encoding (154) the current block of video data using the first precision motion vector for the first current block (120) based on a determination that a reference frame is the closest reference frame temporally to the first current block, generating a first signal value indicative of the use of the first precision motion vector for the first current block, outputting the encoded first current block and the first signal value, determining whether to encode a second current block of video data using the first precision motion vector for the second current block or the second precision motion vector for the second current block, encoding (154) the second current block of video data using the second precision motion vector for the second current block (120) based on a determination that a reference frame is not the closest reference frame temporally to the second current block, generating a second signal value indicative of the use of the second precision motion vector for the second current block, and outputting the encoded second current block and the second signal value.
