METHOD FOR STORING MOVEMENT PREDICTION-RELATED INFORMATION IN AN INTERSCREEN PREDICTION METHOD, AND METHOD FOR CALCULATING THE MOVEMENT PREDICTION-RELATED INFORMATION IN THE INTER-SCREEN PREDICTION METHOD

摘要

Provided are methods for storing and obtaining motion prediction-related information in inter motion prediction method. The method for storing the motion prediction-related information may include obtaining size information of prediction unit of a picture, and adaptively storing motion prediction-related information of the picture on the basis of the obtained size information of prediction unit of the picture. The method for obtaining the motion prediction-related information may include searching a first temporal motion prediction candidate block to obtain first temporal motion prediction-related information in the first temporal motion prediction candidate block, and searching a second temporal motion prediction candidate block to obtain second temporal motion prediction-related information in the second temporal motion prediction candidate block. Thus, a memory space for storing the motion prediction-related information may be efficiently utilized. Also, an error between the prediction block and an original block may be reduced to improve coding efficiency.
