A split block coding method for video coding, a split block decoding method for video decoding, and a recording medium that realizes this.

摘要

PROBLEM TO BE SOLVED: To extend a predictive coding selection method in-screen or between screens for a sub-divided block of a block divided at the time of video coding so that both in-screen and inter-screen predictive coding modes can be selected. And a recording medium that realizes this. SOLUTION: An input screen is divided into coding unit blocks S103, a coding unit block is divided into lower blocks S107, and the lower block is one or more of in-screen predictive coding or inter-screen predictive coding. S111, S112 to be selectively used and encoded. In addition, the decoding process is performed through the reverse process of the coding method. [Selection diagram] Fig. 3
