This article introduces MXL (Media eXchange Layer), a new standard designed to facilitate efficient, low-overhead media exchange between software functions within a broadcast compute cluster. MXL aims to complement existing standards like SDI and ST 2110 by standardizing internal media handling, preventing repetitive packetization and de-packetization overhead for software-defined production workflows. It is positioned as a core component of the EBU Dynamic Media Facility (DMF) reference architecture.
MXL matters because it addresses the part of production ST 2110 does not: media movement between software functions inside the same compute cluster. That gives broadcasters a cleaner division of labor, with SDI and ST 2110 handling ingress and facility transport while MXL handles internal exchange for graphics, AI, mixers, and encoders. The broader signal is that the EBU is formalizing software-defined production around memory, metadata, and orchestration, not just IP transport. Watch the EBU DMF and MXL SDK work, plus how timing, buffer ownership, and vendor interoperability are defined in the reference architecture.
