Abstract (in Japanese) (See Japanese page) 
(in English) Recent all standard video formats are based on BT.601 which was recommended in early 80'. This standard was aimed to keep all of analogue video signal with the gamma conversion (compensation) and 8 or 10 bit quantization includes margin. HDTV standards which were recommended in mid of 90' were changed to square pixel, however, the structure of pixel value were almost kept. On the other hand, PC application of video was dramatically changed, and the correspondence to HDR (High Dynamic Range) image becomes important. Therefore, it is doubtable that the digital video formats based on the analogue extension is best. To realize high versatility and utility of video, we discuss the range coding with plural pixels combination. Further more, to extend tone, the quantization method with offset threshold is proposed. To test the picture quality, pseudo 16 bit HDR images made from 10 bit HDTV are used.
