Abstract

Public communication networks provide a reliable and non expensive means of transmitting relevant Safeguards data. A wide infrastructure has been created for digital communications based on the Integrated Services Digital Network (ISDN) standard from the International Telecommunications Union (ITU) which is widely accessible both for national and international communications throughout Europe. To investigate the use and efficiency of ISDN for the transmission of images. 2 projects have been launched. In the first one, ISDN oriented commercial equipment and aims at the long term testing of image transmission and encryption. The equipment connects up 10 standard colour cameras to a programmable video digitizer which outputs a compressed data stream using the JPEG standard. The data are then passed to an ISDN terminal adapter which establishes the 64 Kbps data link. At the reception, a terminal adapter passes the data to a demultiplexing and JPEG decompression box outputting a standard programmable array logic (PAL) analogue signal. The second project uses a standard personal computer (PC) equipped with an ISDN interface and a video codec board and aims at the evaluation of the use of video conferencing standars for Safeguards remote surveillance. A dedicated software tool box was developed, together with an appropriate user interface. The technical characteristics of the different equipment and the potential of remote surveillance using ISDN are discussed.
