Abstract

Disclosed are methods and devices for providing metadata (120) to be stored. Periods may be indicated by a point at which the metadata becomes valid (150) and a second point at which the metadata becomes invalid (160). The metadata may be encoded, by an encoder (500) in a file format compatible with or based upon an ISO Base Media File format (510). Similarly, the indication of the point at which the metadata becomes valid and the indication of the second point at which the metadata becomes invalid may also be encoded in the file format compatible with or based upon the ISO Base Media File format. This may be performed by a transmitter (400) or by a receiver (470). A plurality of metadata items may also be stored in the file format in a single location providing efficient storage and retrieval.
