METHOD FOR CONVERTING THE FORMAT OF A FRAME INTO A CHROMA SUBSAMPLING FORMAT

摘要

Method for converting a first format frame (402) to one or more second format frames (404). In one embodiment, the method includes the step of accessing a first format frame using n coefficients, where n is the total number of coefficients used for the Y (408), U (410) and V (416) planes of the first format frame. The method further includes the step of 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.
