This working group is in
charge of developing the TV-Anytime Metadata
Specification.
Within the TV-Anytime
environment, the most visible parts of metadata are the attractors/descriptors
used e.g. in Electronic Program Guides (EPG), or in Web pages to describe
content. This is the information that the consumer, or intelligent agents, will
use to search and select content available from a variety of internal and
external sources.
Another important set of
metadata consists of describing user preferences, representing user consumption
habits, and defining other information (e.g. demographics models) for targeting
a specific audience.
The TV-Anytime Metadata
Specification also allows describing segmented content. Segmentation Metadata
is used to edit content for partial recording and non-linear viewing. In this
case, metadata is used to navigate within a piece of segmented content.
The Metadata Phase 1 specification
also covers important system but transport-agnostic aspects such as medadata
fragmentation, indexing, encoding and encapsulation.
Phase 1 focuses on uni-directional delivery
of content but bi-directional access to metadata is also supported.
TV-Anytime Metadata
has now completed Phase 1
and is now working on its adoption and adaption by the various groups with
which TV-Anytime is liaising.
Phase
2 requirements are in preparation of a forthcoming Call for
Contribution. |
