Abstract: With the combination of digital TV and digital networking technologies the transport of professional broadcast services is undergoing a tremendous evolution. After a move from analog to digital, specialized leased lines are progressively being replaced by powerful general purpose ATM (Asynchronous Transfer Mode) based networks. The most critical issue for the adoption of this new technology by the broadcast industry is the transport of live real-time broadcast services, for which the most serious constraints appear. The level of performance, which can be expected for this type of application, is a key point for the end-user broadcaster. Real-time services are most often transported compressed using video compression formats such as MPEG-2 or DV. Transit delay, jitter performance, robustness against transmission errors, synchronization between receivers and emitters are typical parameters to qualify the related constraints. After reminding some key elements of the ATM technology, this paper focuses on performance aspects. The mechanisms put in place, leading to commitments that both the end-user broadcaster and the network operator have to fulfill to meet a given level of performance are explained. Practical performance results are given, and examples of large-scale deployments are described.
