Hello everybody, i need to do scheduled recordings of feeds on different satellites. The problem is that those channels are only active few minutes before transmission and i only have frequency polarization and fec (no pids) as parameters.
Is there any way ProgDVB can record these channels?

What hardware would you suggest as most stable??

thanks

I think best way if you scan this channl one time. Or manual add channel params, but it not easy.

the problem is they are different almost all the times. If i could scan it once i wouldn't have any problem. I need to setup just transponder frequency, polarization, FEC, symbol rate. They are SCPC

Before being scanned, a station does not exist for any DVB software I know. And this for it's not possible to schedule in any way.

Is there any receiver around, that could do this? Either with an internal HDD or at least to automatically switch to such a feed without IDs previously known?

Feed hunters would obviously need a software, that by default records the whole (part) transponder stream multiplex.

Maybe that software would have to know about SCPC (to avoid mistreating regular MCPC transponders), be able to auto detect IDs then, either up to a moment before an event, or even wait until at least A and V IDs are up and active and really start recording then.
Quite often, an SCPC signal does not carry both audio and video from the beginning, and it may as well have them changing several times, before the main event begins.

BTW, feeds don't always have any tables to read from. If not, recording the complete (part) transponder mux would be the only way to go, extract / demux later at playback time, TS reader style.

Just to make it clear, feed do have DVB tables, sometimes they have only usable video but audio is often there. If you take professional receivers (like Tanberg TT1260 for example) you can setup manually all parameters and when the frequency is locked they automatically select 1st service form PMT. I'm sure about this because i've been using this for years. I was wondering if i could do the same with a software.

You can't, with any DVB software I know.

Of course, it must be possible to write some routine for this, but the effort it would take surely depends on the basic working concept. A software, that bases on stations in the first place, does not seem to be the best platform to start from.
For example, even with automatic NIT / PMT / .... reading, a new found station would first have to be entered into the channel database before it could be used the normal way. But once in there, the database is getting re-sorted, stored and re-initiated. That's the moment you can't find that new entry automatically, as you don't know it's location in there. This for, no way to feed the scheduler with data required.

Perhaps even some theoretical ProgDvB plugin might be able to read tables from the outside, like some illegal plugins do it for their purposes, and after the database changes control ProgDVB the way required, as then it would still be able to know the new channel's data.
But I've never seen anything similar yet.

Another new way to go, might perhaps be, to build a new application around the ProgDVB Engine.
But I am not a programmer.

For ideas like this, the best way to go surely would be, to contact software authors directly, like Prog over here. Find his e-mail at the very bottom of each page here.
