Mastering the Integrity of Technical Information in Tapeless Production and Long-Term Archives

Benoit Fevrier, Valerie Popie, Ludovic Dupont

The main challenge for IT teams is to ensure that the media created today will not become obsolete tomorrow. Standards must remain high while, at the same time, all types of information must 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 VANC, VBI, SMPTE 328M and VAUX contain strategic data (timecodes, multi-channel audio descriptions, CC, aspect ratio…), 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 towards the MXF essences to ensure a genuine integrity of metadata in a multi-layered bark. This document provides practical case studies on codec selection, timecode and subtitle carriage, as well as the number of audio channels, including those encoded in Dolby-E.
