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.
