METHOD FOR STORING TEMPORAL MOTION VECTOR AND APPARATUS USING THE SAME

摘要

PURPOSE: A method for storing a temporal motion vector and a device with the same are provided to prevent increases of the size of a memory space and a memory access bandwidth that the temporal motion vector needs. CONSTITUTION: A restored image is filtered in a loop. The dynamic range of a motion vector is restricted. An image and a motion vector are stored in an image buffer and a motion vector buffer. The dynamic range of the motion vector is restricted and stored. The motion vector is a temporal motion vector. The temporal motion vector is used in an encoding/decoding target block wherein the dynamic range of the temporal motion vector is restricted.
