Hi folks,

 

I am desperately trying to create recordings that include HbbTV but it seems that AIT (and also other DVB table information) are not saved within a recorded transport stream.

 

Even though I found the option to "Include AIT in http streams" and tried to record a stream via VLC, the resulting TS does not include an AIT either.

 

So my question is: Is there a way to create a TS that includes AIT or would it be possible to grab the "raw" DVB stream?

 

Cheers,

Bjoern!

The ts only includes the hbbtv url. Going to the live channel and starting hbbtv should give the same result. It requires an extra effort pressing buttons though.
Or do you know a channel where the hbbtv url differs for each program?

Sjaaky, thanks for your reply. Unfortunately it does not really touch my question.

 

Basically I want to record/capture a TS that includes AIT information, stream-events etc. to be able to re-broadcast it (with my own transmitter) in exactly the same way it was casted by the tv station.

 

Openpli creates TS that only contain PAT and PMT but no AIT information which is totally sufficient for recordings but not for my purpose.

I was under the impression that AIT was record by default, by I may be wrong.

 

You DO understand that the contents of the HbbTV are never in the transport stream?

bjoern,

 

if you really want to, add a small patch and it will force ait pids to be included in your recordings

 

Untested and it may not apply on the current OpenPli but you get the idea, I guess

Awsome! That really worked after a long night of building an image for the first time ;-)

 

Thanks a lot radxnl!

As this apparently works fine: is there any reason not to implement this? As it looks like this patch makes 'include AIT' really do what it says.

Look at our commits

Hehe, I looked yesterday, apparently just before the commit was made
