Coding Control of Super High Definition Video for the High Reality Presentation

Abstract

Very high resolution video system such as 4k (4096x2160) enables super close view that distance is almost same as picture height. However, very short distance causes significant different view in a picture. Therefore, uniform processing for a picture may not be always best. At first, we calculate the actual view size of a pixel depends on the pixel position in the case of a picture height distance. the coding performance is checked for the weighted picture in frequency band limitation, contrast conversion and geometric image conversion the coding performance is checked for the weighted picture in frequency band limitation, contrast conversion and geometric image conversion. 4k resolution processing is realized by 4 pattern of HDTV picture coding with H.264 and HEVC. As the results of experiments, the possibility of 10 to 25 percent bit rate reduction is recognized.
