HDR Signaling and Propagation Within IP Workflows

In SMPTE ST 2110 workflows, details about the colorimetry and transfer characteristic of signals (HDR signaling) are not part of the video stream. This talk focuses on system workflows and presumptions within the ST 2110 standard and related NMOS specifications about HDR signaling. In SMPTE ST 2110 workflows, details about the video format, colorimetry and transfer characteristic of signals (HDR signaling) is not part of the video stream. This data is advertised through NMOS (SDP) and it is the responsibility of the control system to track and propagate changes to subscribed receivers in an orderly manner, including managing any effects on network bandwidth. Dynamic HDR metadata from VANC compounds the problem if not tracked alongside the video stream. This talk focuses on system workflow practices within the 2110 and related NMOS specifications around HDR and video format signaling.
