Paper Abstract

This paper reviews image telecommunications standards that exist or are under development. Included are a broad range of services, from facsimile to desktop videoconferencing systems and other multimedia applications. Image compression standards including T.4, T.6, JPEG, JBIG, MPEG, H.261 and H.263, and supporting communication protocol standards are examined. Communication facilities that carry these applications include the switched telephone network (PSTN), Integrated Services Data Network (ISDN), LAN and the mobile cellular telephone system. Still image communication of bilevel, gray scale and color images by means of Group 3 and Group 4 facsimile using T.4, T.6, JPEG and JBIG coding is included. Families of standards for videoconferencing applications (H.320 for N-ISDN, H.324 for PSTN, H.310/H.321 for ATM networks, H.322/H.323 for LAN and the T. 120 multi-point data protocol) are examined. Audio standards that support the videoconferencing applications are reviewed.
