While the primary use of Universal Labels is to identify the type and encoding of data within a generalpurpose data stream or file, other meanings may be associated with specific labels; such additional meanings are beyond the scope of this standard and remain completely within the control of the particular organizations that define those labels.
A specific form of Universal Label, called an SMPTE-administered Universal Label is defined. It is the mechanism used to identify and distinguish data contained in data streams or files that have been generated according to the provisions of other SMPTE Standards and Recommended Practices.
