Editorial Reviews

Describes recent developments in the technology and standards for communicating multimedia signals through such media as videophones, video teleconferencing in the conference room or on the desktop, and remote access to multimedia databases. Primarily concerned with new standards developed by the ITU and ISO that define the procedures, to which Schaphorst himself has contributed significantly. Video compression techniques, speech coding, mobile radio, local-area networks, and multipoint graphic communication are among the topics. No bibliography. Annotation c.
