Abstract:
Provided are an inter prediction method and a motion compensation method. The inter prediction method includes: performing inter prediction on a current image by using a long-term reference image stored in a decoded picture buffer; determining residual data and a motion vector of the current image generated via the inter prediction; and determining least significant bit (LSB) information as a long-term reference index indicating the long-term reference image by dividing picture order count (POC) information of the long-term reference image into most significant bit (MSB) information and the LSB information.

Claim (Index 1):
A video decoding apparatus comprising:\n a receiver to receive a bitstream; and a motion compensator to obtain, from the bitstream, LSB (Least Significant Bits) information regarding picture order count (POC) information of a current long-term reference image of a current image, to determine MSB (Most Significant Bits) information regarding the POC information of the current long-term reference image of the current image based on MSB information regarding POC information of a previous long-term reference image of the current image and a difference between the MSB information regarding the POC information of the current long-term reference image and the MSB information regarding the POC information of the previous long-term reference image of the current image, to determine the POC information of the current long-term reference image of the current image by using the LSB information and the MSB information regarding the POC information of the current long-term reference image of the current image, and to reconstruct the current image by using the current long-term reference image of the current image corresponding to the POC information of the current long-term reference image of the current image, wherein the MSB information regarding POC (Picture Order Count) information of the current long-term reference image of the current image is information regarding a quotient generated by dividing a value related to the POC information of the current long-term reference image of the current image by a maximum size of the LSB information, and the LSB information is information regarding a remainder value generated by dividing the POC information of the current long-term reference image of the current image by the maximum size of the LSB information.
