Reliability for Media Systems: Patterns and Anti-Patterns in Design and Operations

Software-intensive systems have become pervasive in media facilities, and as systems and their components fail in new ways, the traditional design strategy of reliability through hardware redundancy has become less effective. Designers must consider not only hardware failures arising from physical phenomena, which tend to be independent between units or correlated only with factors such as equipment age and temperature, but also software failures, which are more likely to affect multiple units simultaneously and to propagate spontaneously between units. This tutorial paper reviews reliability engineering fundamentals and traditional reliability prediction methods for electronic equipment and systems. Through examples drawn from the authors' experiences in large-scale television production and distribution facilities, the limitations of this hardware-centric perspective and the implications for system and facility design are explored. Design and operating strategies to reduce the risk of software failures and mitigate their consequences are discussed, with an emphasis on practical application to media facilities. Systems engineering techniques such as failure mode and effects analysis and fault tree analysis are also described.
