Abstract(in English) As the next generation video application, ultra-high resolution video whose resolution is much higher than conventional full HDTV is quite attractive, and the new encoding scheme which gives higher coding performance than H.264/MPEG-4 AVC is strongly required. As the related work, extending macroblock size schemes are proposed to effectively eliminate the redundancy under the pretty high spatial correlation as the representative feature of ultra-high resolution video signals. Among conventional extending macroblock size schemes, the spatially adaptive macroblock size selection based on the analysis of spatially local image feature within a video frame is regarded as the potentially effective approach. In this paper, the effectiveness of the spatially adaptive macroblock size selection scheme is strictly evaluated for 7680x4320 resolution sequences under the practical condition for encoder parameters.
