Abstract
Systems and methods for storing notification messages in an ISO base media file are provided, where different transport cases when notification messages are to be stored are addressed. The systems and methods enable the linking of notification message parts delivered over RTP with other parts of a notification message carried over file delivery over unidirectional transport (FLUTE) or some other protocol. Various implementations of the systems and methods can be generic and allow objects delivered out-of-band to be referenced from media and hint tracks. Additionally the lifecycle of notification objects can be reproduced in the file without timers required in the parsing of the file.

A method of organizing media data and metadata, comprising:
- storing the media data in a file;
- storing a first part of the metadata in the file, the first part of the metadata being synchronized with the media data and comprises a state of a notification object lifecycle model, and;
- indicating in the file the synchronization of the first part of the metadata relative to the media data;
- storing a second part of the metadata in the file, wherein the second part of the metadata comprises a notification message;
- and
- indicating in the file that the first part of the metadata and the second part of the metadata are logically connected.
An apparatus, comprising:
- a processor configured to:
- store media data in a file organizing the media data and metadata;
- store a first part of the metadata in the file, the first part of the metadata being synchronized with the media data;
- indicate in the file the synchronization of the first part of the metadata relative to the media data and comprises a state of a notification object lifecycle model, and;
- store a second part of the metadata in the file, wherein the second part of the metadata comprises a notification message;
- and
- indicate in the file that the first part of the metadata and the second part of the metadata are logically connected.
A method of processing an input file including at least one notification message, comprising:
- performing at least one of:
- parsing the input file to extract information corresponding to a notification object of the at least one notification message;
- and
- producing an output file, wherein states of the notification object have been pre-computed.
An apparatus, comprising:
- a processor configured to perform at least one of:
- parse an input file including at least one notification message to extract information corresponding to a notification object of the at least one notification message;
- and
- produce an output file, wherein states of the notification object have been pre-computed.
