Abstract: PURPOSE: A bit rate control method and a device thereof are provided to perform real time bit rate control for encoding an ultra definition video by considering a hierarchical encoding structure. CONSTITUTION: A bit rate control unit allocates a bit amount for an intra section (S430). The bit rate control unit allocates a bit amount for a Group Of Picture (GOP) (S440). The bit rate control unit allocates a bit amount by frame (S450). The bit rate control unit applies a bit amount allocation weighted value to each hierarchy level by using a relative ratio of each result bit amount after performing initial frame encoding to each frame type/hierarchy level by using an initial quantization parameter. [Reference numerals] (AA) Start; (BB,DD,FF) No; (CC,EE,GG) Yes; (HH) End; (S410) Determine an initial quantization parameter; (S420) Encode an I frame; (S430) Allocate a bit amount for an intra section; (S440) Allocate a bit amount for a GOP; (S450) Control a bit rate by frame; (S460) Has the current GOP ended ?; (S470) Has the current intra section ended ?; (S480) Has an image encoding process ended ?

Abstract: PURPOSE: A method and apparatus for estimating an image intra and a method and apparatus for decoding an image by applying the same are provided to improve the quality of a decoding target image by an intra prediction in a compression decoder. CONSTITUTION: An image intra predicting apparatus backs up a boundary pixel value of a decoding target block(410). The boundary pixel value of the decoding target block is corrected based on a correlation between boundary pixels and adjacent pixels(420). The decoding target block is predicted according to an intra mode based on the corrected boundary pixel value(430). The boundary pixel value of the backed up decoding block is restored(440).
