    摘要: A motion vector predicting method and apparatus for predicting motion vectors in image coding and decoding, including predicting a motion vector of each small block in a macro block divided into at least one small block. The method may include selecting at least one small block, where a motion vector can be estimated, using motion vector information of adjacent small blocks, and includes simultaneously performing a motion vector prediction of the selected small block. By reducing a 16-operation process, conventionally required for processing a macro block with 4×4 blocks, into an 11-operation process, the image coding and decoding processing times can be reduced without using a complicated motion vector predicting apparatus.

    摘要: Provided is a method for encoding and decoding a motion picture frame, which achieve natural picture conversion of frames near an Instantaneous Decoding Refresh-I (IDR-I) frame. The decoding method includes: decoding a first frame which is a P frame that is to be displayed last among a plurality of P frames that are to be displayed before an IDR-I frame is displayed; decoding the IDR-I frame; decoding a second frame which is a P frame that is to be displayed first among a plurality of P frames that are to be displayed after the IDR-I frame is displayed; and maintaining a reference frame stored in a buffer, for decoding the first frame until the second frame is decoded. Therefore, by allowing frames near an IDR-I frame to access reference frames stored in a buffer, natural picture conversion is possible, and accordingly smooth picture conversion without flickering is possible.
