Over the past two decades, the movie theatre industry has undergone a digital transformation, with traditional film projection technologies being replaced by Digital Cinema technologies. SMPTE has established a comprehensive set of D-Cinema standards covering everything from digital copies (DCPs) to theatrical release. Despite this, the management of databases for the vast number of movie theatres worldwide—each equipped with Digital Cinema technologies like projectors, servers, and IMBs—remains outdated. Currently, there are no industry-wide mechanisms for automatically registering or updating D-Cinema equipment databases, which are often maintained independently by studios, distributors, and laboratories. This lack of integration complicates the management of Key Delivery Messages (KDMs), which enable encrypted content playback. In contrast, the television broadcast industry has seen rapid advancements in IP technologies, particularly with the adoption of SMPTE ST 2110 standards and NMOS AMWA open specifications. These specifications facilitate the discovery, registration, and management of networked media devices. Applying NMOS principles to the Digital Cinema sector could address current challenges by enabling automated discovery, registration, and management of D-Cinema equipment through a unified networked framework. This approach could significantly enhance the efficiency and accuracy of managing D-Cinema nodes, aligning with the rapid technological progress in media industries.
