FAST INTRA MODE DECISION METHOD IN H.264 ENCODING

摘要

PURPOSE: A fast intra mode determining method during H.264 encoding is provided to determine intro mode at high speed using encoding information of a reference frame. CONSTITUTION: A corresponding macro block of the same location as a current macro block of a current frame is searched from a reference frame(500). When the current macro block and the corresponding macro block are non-variable, intra mode determined for the corresponding macro block is determined as intra mode of the current macro block(504). When the current macro block and the corresponding macro block are not non-variable, the intra mode of the current macro block is determined by an intra mode estimation scheme(506).
