摘要
This invention is a 2-slice MPEG-2 coding method. The MPEG-2 standard defines the slice structure where that the first and the last macroblock of a slice are in the same horizontal row of macroblocks. Two vertically adjacent macroblocks belong to two different slices. Any MPEG-2 slice can be decoded or encoded independently of other slices in the same frame because there is no dependency between slices. Due to these properties, this invention can decode or encode two consecutive macroblock rows alternately to fit the H.264 MBAFF scan order. This reduces the external memory access bandwidth and imposes no frame delay between decoder and encoder.
