METHOD AND APPARATUS FOR INTER-PREDICTION AND MOTION-COMPENSATION

摘要

PURPOSE: An inter prediction method, a device thereof, a motion compensation method thereof, and a device thereof are provided to save an extra image number storage space for only a long-term reference image by pointing the long-term reference image by using POC(Picture Order Count) information. CONSTITUTION: An inter prediction device performs the inter prediction of a current image by using a long-term reference image stored in a DPB(Decoded Picture Buffer)(13). The inter prediction device a motion vector and residual data of the current image according to the inter prediction(15). The inter prediction device determines LBS(Least Significant Bits) information as a long-term reference index by dividing POC information into MSB(Most Significant Bits) information and the LSB information(17). [Reference numerals] (13) Perform an inter prediction using a long-term reference image; (15) Determine a motion vector and residual data; (17) Determine LBS information for POC information of the long-term reference image; (AA) Start; (BB) End
