The content description of multimedia content contains a plurality of
descriptor values that pertain to specific events within the media. A
Transport Hint Table (THT) provides a set of synchronization events that
indicate the relation between timed events in the media and their
representation in the content's description data. The THT allows for
synchronized delivery of presentation of content description data with
the associated events in the media. The THT provides a set of sync events
based on the existence of "time" related events obtained from the content
description data, which are relevant to particular events in the media.
The THT allows the transport layer encoder to use the time-related events
to synchronize the scheduled delivery times of media content segments and
their associated descriptions. The THT also provides information for
fragmenting a description for delivery and for managing resources at the
decoder.
