SMPTE publishes Study Group report on much-debated HDR imaging ecosystem
The Society of Motion Picture and Television Engineers (SMPTE) announced at the SMPTE 2015 Annual Technical Conference & Exhibition the publication of the SMPTE study group (SG) report on the high-dynamic-range (HDR) imaging ecosystem. The work of 170 top international experts, the SMPTE SG report summarises an extensive discussion on the implementation of HDR in professional media workflows and addresses key questions that will arise for industry members as they move forward in taking advantage of HDR technology. The report also offers recommendations for further HDR standardisation efforts by SMPTE and other organisations.
“HDR is a rapidly emerging and much-debated technology with the capacity to make a greater impact on viewer experience than can higher-resolution formats,” says Alan Lambshead, vice president of standards for SMPTE. “Recognising the remarkable potential of HDR and the media industry’s growing interest in this technology, SMPTE created an HDR ecosystem study group and — within just 12 months — delivered a valuable consensus report on implementation of HDR and the creation of efficient HDR workflows.”
The SMPTE SG report on the HDR ecosystem provides consensus guidance on HDR terms and definitions and presents detailed and useful information on HDR technologies that, up to this point, has not been readily available to the media industry. The report acknowledges that although HDR technologies, both proprietary and standardised, are available today and already can be implemented for non-real-time workflows, challenges remain in live or real-time applications.
It further recognizss that implementation of HDR will be complex and affect many systems in a professional media workflow. The report catalogs HDR technologies, examines issues in both live and non-live HDR workflows, and describes the role of HDR metadata. Finally, it recommends industry harmonisation regarding HDR technologies and parameters, stressing the importance of standardising new technologies related to HDR and of updating current standards to enable HDR.
“Interest in HDR has begun to explode, and this report on the HDR ecosystem has been eagerly anticipated by engineers and technologists across the media industry,” says Thomas Bause Mason, SMPTE Technical Committee (TC) 10E SG on HDR Ecosystem chair. “We are confident that this timely SMPTE publication will answer many of the questions that emerge as HDR is discussed and implemented.”
