Abstract

We have investigated super high definition (SHD) images supporting resolutions beyond 2048×2048 pixels/frame with 24-bit color separation at 60 frames/s for many professional applications of multimedia communications. However, 6 Gbps is needed to transmit moving SHD image sequences without any compression. This paper expands the MPEG2 standard from main profile at high level (MP@HL) to main profile at super high level (MP@SHL) to transmit SHD images via B-ISDN networks. The transmission of MPEG2 compressed SHD images over ATM networks is simulated. The strong burstiness of compressed SHD images is clarified and the transmission characteristics of these images over 155 Mbps and 600 Mbps ATM lines are determined
