Forward-looking perspective on the future of television broadcasting
In a groundbreaking development, the European Broadcasting Union (EBU) has announced the Media eXchange Layer (MXL) as the key focus for its Dynamic Media Facility (DMF) project [1]. Launched in April 2023, the DMF initiative aims to explore the benefits of highly flexible and dynamic technology approaches for future media productions [2].
The MXL, an open-source code package, is designed to standardize how media processing functions in virtualised environments can share and exchange data with each other [3]. This standardisation is crucial for the DMF vision of replacing traditional, dedicated hardware boxes with virtual containers running on local servers or in the cloud [1].
At the heart of MXL lies its role as a data exchange standard and integration layer. It allows different media processing functions, encapsulated as containerized applications, to communicate seamlessly [1]. This enables dynamic, flexible, and scalable media production workflows that can adapt to rapidly changing requirements and leverage cloud and IT infrastructure advances [1].
The DMF project's reference architecture consists of three major blocks: IT architectures, media infrastructure, and aspects that cut across all layers, such as discovery, monitoring, and security [4]. MXL plays a pivotal role in the media infrastructure block, providing the "virtualised cabling" that facilitates the DMF vision [5].
The Linux Foundation and the North American Broadcasting Association (NABA) have become closely involved with the development of MXL [6]. Several workshops and seminars are scheduled for MXL, with the expectation that people will contribute to the code, download it, and use it [7].
The initiative has already gained attention, with DMF being a vibrant topic at NAB and discussions about it at other events [8]. The EBU has published a full archive of white papers and publications related to DMF and MXL, which can be accessed at https://www.ebu.ch/home [9].
The DMF project aims to develop a Reference Architecture that offers a structured framework for users to express and evaluate their requirements using common models, interfaces, and terminology [10]. The project also plans for extensive documentation, including use cases that will benefit from a DMF approach, and a high-level model for the lifecycle of media workloads as part of the Reference Architecture [11].
NABA hopes that MXL will help improve and streamline workflows in the future by maximising flexibility and interoperability. This will provide broadcasters with the ultimate freedom to customise their facilities to their specific needs and to provide options among vendors [12].
As the DMF project and MXL continue to evolve, they promise to revolutionise media production, offering a more efficient, flexible, and scalable approach to media processing workflows.

The MXL, as a crucial part of the DMF's media infrastructure, serves as a data exchange standard and integration layer, enabling seamless communication among different media processing functions, and facilitating a dynamic, flexible, and scalable media production workflow. This workflow leverages advancements in data-and-cloud-computing technology and relies on virtual containers running on local servers or in the cloud.
