The previously developed universal pattern-matching coding technique (PMC) uses different coding modes, and adaptively chooses the proper coding mode instantaneously for a given input subblock. To improve the adaptability of the coding-mode selection, we introduced the delayed-decision mechanism with the (M,L) algorithm, which can be considered a kind of multi-path tree search algorithm, and reported its superiority over the existing instantaneous coding-mode selection. However, the coding performance of our previousely developed method degraded because of the discontinuity of raster scanning. The work herein proposes a scanning which does not contain any discontinuity and demonstrates that this scanning method improves coding performance to some extent.
