IPMX is a collection of standards and specifications for AV over IP that are making their way through VSF and AMWA, with heavy support and evangelism from AIMS. IPMX starts with ST 2110 and NMOS and the bits and pieces for Pro AV and Pro AV use cases. However, there is a lot of live production happening in Pro AV, which is a major goal of IPMX. In this talk, we will see how IPMX is different than ST 2110, how it extends it and what features are interesting for live production and interoperability with ST 2110.
