As one of the applications of ultra high-definition image, we focus on the 3-dimensional CG (Computer Graphics) close to reality with radiosity methods. We have developed the technology to convert the image quality on the transcoding proxy distributed on network in response to the clients and to reduce the load on the contents server and the network in delivering the generated CG images to multiple points on the Internet. Moreover, we conducted the experiment in the communication sharing CG image, moving image and sound in multiple points.
