Abstract
The transition to video surveillance systems for international safeguards requires the provision of special components, indispensable to the maintenance of reliable and authentic video information. Under the Federal Republic of Germany Support Programme for the International Atomic Energy Agency, a tamper resistant TV-link (TRTL) was developed to authenticate video signals passing through standard transmission lines (coaxial cables, optical fibres) which are assumed to be accessible to third persons. The TRTL is a universal tool for optical video surveillance systems in international safeguards. It includes error report facilities and service help. The user can choose a simple one-to-one authentication between a video signal and a recording device or a multiplexed, multichannel, multiprocessor system. A limited performance evaluation in view of a production model, suitable for multiplexed TV-applications will be conducted in 1989. For these tests, a computer controlled 'tamper box' will be used to insert a v?riablc number of pixels into the video signal at random locations. The paper describes the final design concept of the TRTL, the test conditions and perspectives for commissioning.
