METHOD FOR VIDEO ENCODING MODE SELECTION AND A VIDEO ENCODING APPARATUS PERFORMING THE SAME CAPABLE OF EFFICIENTLY SELECTING A VIDEO CODING MODE SUITABLE FOR A VIDEO

摘要

PURPOSE: A method for video encoding mode selection and a video encoding apparatus performing the same are provided to select an appropriate encoding mode by effectively calculating rate-distortion costs.;CONSTITUTION: A video coding apparatus transforms an original image block into a frequency domain(610). The apparatus quantizes the transformed image block(620). The apparatus presumes the distortion of coding block corresponding to a coding mode(630). The apparatus presumes the coding rate of the coding block corresponding to the coding mode(640). The apparatus selects suitable coding mode(670).;COPYRIGHT KIPO 2012
