We have developed a digital move communication system for SHD images. The system can transmit extra high quality digital full color movies of 2048 by 2048 pixel resolution using 622 Mbps ATM transmission systems, and display them at the frame rate of 60 frames per second. The system consists of an image data server, ATM transport interfaces, a real-time JPEG decoder and an SHD image display frame buffer. The motion SHD images have such high quality that the system has been designed for professional movie applications such as tele- medicine, education and commercial movie theaters. The image data server is constructed on a workstation to store motion image data and transmit them to the decoder via 622 Mbps ATM links. The real-time decoder is a parallel DSP system to decode the received movie data stream into raw SHD move images. The frame buffer is connected to the decoder via optical links offering at total of 12 Gbps to show complete movie images on CRTs or large size projectors.
