What is the IMF UG?
The Interoperable Master Format (IMF) User Group (UG) is a forum for the worldwide community of end-users and implementers of the IMF family of standards.
The IMF UG brings together content owners, service providers, retailers and equipment/software vendors to enhance and promote the use of IMF globally, across domains of applications. The IMF UG discusses technical operational issues that arise in practical implementation, conducts and cooperates with other industry bodies and standards organizations on interoperability testing, develops best practices, and seeks to broaden the awareness of IMF.
The IMF UG is organized under the umbrella of the HPA.
