Abstract

Variable bit rate high-definition-television (HDTV) communication in asynchronous-transfer-mode (ATM) networks is discussed. Terminal functions required for support of variable-bit-rate HDTV communication are outlined. Detection of lost and misdelivered cells, handling of cell delay variation, source clock frequency recovery, and segmentation and reassembly of user information are shown to be adaptation layer requisites. Multimedia multiplexing, virtual channel control, and required network quality for multimedia communication are also discussed. Adaptation functions for intrafield adaptive differential pulse-code modulation coding are described, and an experimental HDTV codec and an ATM terminal adapter are presented
