SMPTE 298M-1997

This standard defines universal labels, a universal labeling mechanism to be used in identifying the type and encoding of data within a general-purpose data stream. The labeling mechanism is intended to function across all types of digital communications protocols and message structures, allowing the intermixture of data of any sort. Labels created using the mechanism specified are intended to be attached to the data they identify and to travel together with them through communications channelsThis standard defines universal labels that can be used by any organization that wishes to label data in a manner that is universally unambiguous, globally unique, and traceable to the authorizing organization.
