The group has two main working areas:
-
Metadata
Definition of all information pertaining to the location,
identification and characterisation of DVB services and programme
events. The group also specifies mechanisms and protocols for the
conveying of such information.
-
Generic Data Broadcast
Definition of mechanisms and protocols for the broadcast of
non-audiovisual content for both streaming and non-streaming modes.
This includes the case of tunnelling for other protocols (e.g. IP).
The above is laid out in the restated and
amended Terms of Reference of the group which were approved by the TM
in January 2003.
The group has been active since the beginning of
the DVB Project (see history outline below) and held its 50th meeting
in early 2002. It has produced some of the core specifications of
today's DVB system (e.g. Service Information, Data Broadcast, Software
Update; see below). As the group's working areas are at the foundation
of the system, the end of its activities is not foreseen.
Should you have any further questions or comments, please contact the Chairman.
NOTE: Dear colleagues, the below history is largely based
on assumptions and guesswork. I would therefore like to ask those of
you who are by far more knowledgeable about this to provide the
necessary information to help make the history table more accurate.
Thank you very much, --Alexander Adolf
