Adaptive Video Distribution Model with Tile Structure of JPEG2000 : QHD Still Image Version

Abstract

We authors are aware of the further spread of the high-definition system and have developed the following two (next generation) formats that can provide even higher visual precision: one is WHO format (Wide/Double HDTV:3840*1028 pixels) that has twice as much pixels as existing HDTVs in the horizontal direction. The other is QHD format (the Quadruple HDTV:3840*2048 pixels) , which has twice as much pixels in both vertical and horizontal directions and accomplishes the precision equivalent to or beyond that of 35mm films. This paper describes the overview of the concept of WHD/QHD camera and projector that we have been researching and developing. We also would like to propose an image distribution model as one of the applications of WHD/QHD images for homes. Using the tiling function of JPEG2000, this model offers the contents which are effective, high precision and adapted for a viewers' needs.
