Abstract
Some examples include a video encoding/decoding technique for improving compression efficiency. For instance, the technique includes selecting a prediction mode to be performed among a plurality of prediction modes including an intra-prediction mode and an inter-prediction mode. The technique further includes calculating a predictive motion vector in case an inter-prediction mode is selected as the prediction mode to be performed, and calculating a motion vector by summing the calculated predictive motion vector and a differential motion vector decoded from a coded stream, in case the inter-prediction mode is selected as the prediction mode to be performed. Further, some examples may include performing an inter-prediction process of the selected prediction mode using the calculated motion vector in case the inter-prediction mode is selected as the prediction mode to be performed.
