Method and device for video down-sampling transcoding

摘要

image reduction transcoding method and apparatus . Image reduction transcoding method according to an exemplary embodiment is inputted CIF (Common Intermediate Format) size of the MPEG simple profile in the video bit stream to the pixel domain image (Pixel Domain) reduces by 1/2 QCIF (Quarter CIF) size of the H .264 baseline profile is converted into a video bitstream . Can be performed in the MPEG-4 to H.264 image reduction by the present invention at a high speed .
