The rapid shift towards Ethernet-based technologies in ProAV systems has exposed signi?cant challenges in the integration and convergence of diverse media transport protocols. Con?icting assumptions among de facto and o?cial standards about underlying network features often result in severe incompatibilities. The situation is exacerbated by the absence of an overarching use case model to guide the development and application of these protocols. To address this, the authors propose a generic use case model grounded in real-world ProAV requirements, especially for live events and productions. This model focuses on system integration and interoperability, taking into account the coexistence of various signal and control tra?c types, loose collaborative teams, and the contrast to traditional IT network design principles. Through this model, the authors aim to clarify requirements, shape realistic expectations for products and implementations, and stimulate discussion for the next evolution in AV networking.
