Embodiment Construction

[0049] Within the DVB Association, a common file format has been designed to be used for content exchange between all DVB compatible devices. This DVB file format is based on the ISO base file format, which is standardized in ISO / IEC 14496-12. An amendment to this standard proposes timed metadata tracks and is identified as ISO / IEC 14496-12:2005 / Amd 1:2007. However, even if revised, this standard still has limitations. It would be beneficial to extend the design of the common file format. For example, it may be possible by defining a way to store descriptive metadata in a DVB file that follows the existing DVB metadata scheme. Furthermore, portions of metadata may be linked with portions of content, be it audio, video, graphics, text, or the like. It is also desirable to provide a flexible and hierarchical linking structure. This would allow some parts of the metadata to be valid for most of the content, while other parts would be valid for shorter periods of time during t...

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.
