摘要： Disclosed are an image encoding method using a skip mode and a device using the method. The image encoding method may comprise the steps of: judging whether there is residual block data of a prediction target block on the basis of predetermined data indicating whether residual block data has been encoded; and, if there is residual block data, restoring the prediction target block on the basis of the residual block data and an intra-screen predictive value of the prediction target block. Consequently, encoding and decoding efficiency can be increased by carrying out the encoding and decoding of screen residual data only for prediction target blocks where there is a need for a residual data block in accordance with screen similarity.

摘要： A water ring scanning apparatus configured to process an initial data set, such as a video frame, is disclosed. The water ring scanning apparatus is configured to write a portion of data from the initial data set into a data string. The initial data set is organized with at least one initial origin enveloped by a plurality of nested initial environs successively surrounding each other in the initial data set. The scanner is configured to write a portion of the data from the initial data set into the data string by starting at the RC grouping corresponding to the initial origin (initial water ring (0)) and by sequentially progressing outwardly from the family of RC groupings corresponding to the nearest nested initial environ (initial water ring (1)) towards the family of RC groupings corresponding to a furthest nested initial environ (initial water ring (n)).
