Hi StuartA, Dekarl, et al.
Have any of you guys been thinking more about adding DVB Running Status
information to our EIT processing. In some discussions on EIT tables we
had a long time ago, I mentioned that I was thinking of looking into it.
It has got to the top of my list again :-)
Running Status is used in a number of areas of the DVB spec, but the one
of interest is the running status contained in the EIT. This gives the
on air status of an EIT entry.
0 - undefined
1 - not running
2 - starts in a few seconds
3 - pausing
4 - running
5 - service off air
6,7 - reserved for future use
So I think it might be a good idea to use the scheduled start time from
the EIT to cold start the backend (idle shutdown/wakeup) and the running
status to start the recording or stop recording. State 2 is specifically
provided for this purpose. State 3 is intended for multi part events
e.g. a long film interrupted by the news (It may also be useful for
marking commercial breaks).
DVB also provides a Running Status table. This table is intended to
provide near real time updating to the running status field of
individual EIT entries.
I have more thoughts on this, but I would like get feedback first.
Any comments?
Roger
