A method ( 400 ) of aspect ratio conversion for an imager ( 16 ) having random row access includes the steps of periodically receiving ( 402 ) a predetermined number of input video lines, vertical format converting ( 404 ) the predetermined number of input video lines to provide a converted video input having a portion of the predetermined number of input video lines, and periodically multiplexing ( 406 ) a black input line with the converted video input during a waiting period during the vertical format converting step. The method can also include the step of presenting ( 408 ) on the imager the converted video input along with a plurality of black lines that were periodically multiplexed with the converted video input.
