Abstract:
1. A method of encoding a video by considering a skip and split order, the method comprising: splitting a picture into a maximum coding unit including coding units being data units in which the picture is encoded; for the maximum coding unit, determining coding units having a tree structure including coding units of coded depths and determining encoding modes for the coding units of the coded depths by performing encoding based on coding units according to depths, the coding units according to depths obtained by hierarchically splitting the maximum coding unit as a depth deepens and the depths being proportional to a number of times the maximum coding unit is split; and outputting information about a maximum coding unit size and, for the maximum coding unit, information indicating an order of split information and skip mode information which is selectively determined for the coding units according to depths, information about the encoding modes for the coding units of the coded depths including the split information and the skip mode information which are arranged according to the order, and encoded video data, wherein the information indicating the order of the split information and the skip mode information indicates whether the split information precedes the skip mode information in the information about the encoding modes, or whether the skip mode information precedes the split information in the information about the encoding modes, wherein the information indicating the order of the split information and the skip mode information indicates, for a first coding unit in the maximum coding unit, a first order of the split information and the skip mode information, and wherein the information indicating the order of the split information and the skip mode information indicates, for a second coding unit in the maximum coding unit, a second order of the split information and the skip mode information, different from the first order.
