ABSTRACT:
Provided is a fast mode-searching apparatus and method for motion-prediction. The fast mode-searching apparatus includes a probability information obtaining unit, a first inter mode searching unit, a second inter mode searching unit, and a selective intra mode searching unit. The probability information obtaining unit detects whether at least one of a macroblock of a previous frame, a macroblock of a current frame, and adjacent macroblocks corresponds to at least one of P16×16, P16×8, and P8×16. The first inter mode searching unit performs an inter mode search on a block that is not detected by the probability information obtaining unit. The second inter mode searching unit determines whether the macroblock of the current frame corresponds to P16×16 as a result of performing the inter mode search on a block detected by the probability information obtaining unit. The selective intra mode searching unit performs an intra mode search if the macroblock of the current frame corresponds to P16×16.
