Description

Hi there, for some time now (possibly for over a year), i've noticed that certain channels (from one multiplex) do not contain content-type (or category) information in the OTA EPG.

Other multiplex/channels have the content-type information, just not one specific multiplex.

So, the multiplex in question is
  • Nine Network Australia
  • 191,625 kHz
  • QAM64
  • 7Mhz
  • 8k mode
All channels on that lutiples do not have content-type, the channels include
  • Nine Digital
  • GEM
  • GO!
  • EXTRA
All the other multiplexes seem to have atleast some content type for their EPG, they include
  • Seven network
  • Ten Brisbane
  • ABC
  • SBS

I'm certainly no expert, but i'm wondering if there is a mismatch in the category coming through for the Nine Netwrk multiplex, that doesnt match the pre-determined categories that TVHeadend expects. Jsut a guess, but I've got no idea how to look into it...

Any ideas?

Cheers Nathan

I'd say that's unlikely the content type is transmitted as a single byte that is clearly defined in the DVB/EIT spec. So unless that one transponder is using something out of spec I'd say the explanation is likely to be something else.

Either no content type is being transmitted, or something else is going wrong which means TVH is not getting to the point of processing the content type. Though I think the code is written such that it must retrieve all information before it will make any entry in the EPG.

Possibly a small raw TS dump of the effected transponder might help.

Ok, i'll have a go... is there a guide on how to extract a TS dump from TVHeadend?

Hi there, I recorded SinCity to find out which adapter to enable "full mux dump" for, then enabled it for that adapter, then recorded EmbarrasingBodies. I assume the muxdumps is what you are after. Hope this is the correct stuff?
