ST 429-5:2009 - SMPTE Standard - D-Cinema Packaging — Timed Text Track File

This standard specifies the format of a Timed Text Track File for the distribution of D-Cinema timed text content using the Material Exchange Format (MXF). The Track File is a container for an XML document and optional support resources such as images or fonts.
