Abstract: The main challenge for information technology teams is to ensure that the media created today will not become obsolete tomorrow. Standards must remain high, while all types of information continue to be accessible. In workflow architecture, key decisions revolve around choosing the right audio/video codecs to guarantee maximum interoperability. However, although various layers such as vertical ancillary (VANC), vertical blanking interval (VBI), SMPTE 328M, and video auxiliary (VAUX) contain strategic data (time codes, multichannel audio descriptions, closed captioning, aspect ratio, etc.), they are not sufficiently taken into account in operation processes. This valuable information often comes embedded in the input source video stream and must be directed toward the Material Exchange Format (MXF) essences to ensure a genuine integrity of metadata in a multilayered bark. This document provides practical case studies on codec selection, time code and subtitle carriage, as well as the number of audio channels, including those encoded in Dolby-E.

bio
Benoit Fevrier obtained a master's degree in computer science from the University of Bordeaux, where he acquired extensive knowledge in Digital Image Engineering. He began his professional career working on several R&D projects—in particular the 5th PCRD EU “G-FORS” project, which involved BBC, Philips, and Snell & Wilcox. In 2003, he founded OpenCube, a Toulouse–based company, which provides MXF solutions for the broadcast and D-Cinema industries. In 2010, OpenCube Technologies was acquired by EVS, a global leader in broadcast and media production systems. Fevrier is currently general manager of the OpenCube business unit in the EVS group, where he continues to carry out MXF tapeless workflow analyses, among other activities.
Valerie Popie
bio
Valérie Popie is an engineer with a master's degree in software design and architecture from the University of Le Mans, France. She started her career at OpenCube in 2006 as a software engineer and is now product manager of the EVSOpenCube MXF software product line, where she works, among other things, on SMPTE standardization for comprehensive MXF implementation in EVS-OpenCube Products. Popie has developed an in-depth knowledge of the theoretical and practical aspects of MXF implementation as well as significant expertise in real-life MXF-based workflow interoperability and metadata management issues.
Ludovic Dupont
bio
Ludovic Dupont holds a master's degree in computer science from Toulouse's Paul Sabatier University of Science with a specialty in digital image engineering. Dupont started his career at OpenCube in 2004 as one of the very first employees of the “start-up.” He is now project leader of EVS-OpenCube video server product range; his R&D activities are focused in large part on the challenges of preserving and transferring metadata from physical baseband video streams to MXF files for tapeless production workflows.
