Abstract

Macroblock level Horizontal Spatial Prediction(HSP) based intra frame coding scheme for High Dimension(HD) video sequences was proposed in this paper. According to the correlation experiment on HD sequences, most HD pictures have the stronger horizontal spatial correlation than the vertical spatial correlation, about 2dB stronger. This phenomena drop a valuable hint to us that the horizontal spatial prediction can be used in HD video intra coding without considering the vertical spatial prediction. An adaptive divide and predict intra frame coding scheme has been proposed by Piao which has the similar idea. But this method divided the whole picture into several parts which is not conform to the conventional macroblock based video coding framework and it has the high computation complexity in motion estimation procedure.
