Welcome to the IEC Television Metadata Dictionary
The metadata dictionary defined in IEC 62261 covers the use of metadata for all types of essence (video, audio, and data in their various forms). It is maintained by TC 100 / TA 6 (Audio, video and multimedia systems and equipment / Higher data rate storage media, data structures and equipment).
The dictionary structure provides flexibility in capturing metadata and exchanging it among applications through a standardized hierarchy of universal labels for the metadata elements, grouped to aid their management within a small but comprehensive number of classes. Metadata classes are collections of metadata elements with common characteristics or attributes. Additional classes are provided for user-defined metadata.
