Abstract
Converting a first format frame to one or more second format frames. In one embodiment, a method includes accessing a first format frame using n coefficients, where n is the total number of coefficients used for the Y, U and V planes of the first format frame. The method further includes mapping the coefficients of the first format frame to coefficients of one or more second format frames. The one or more second format frames have n coefficients across all of the second format frames matching the n coefficients of the first format frame.
