I've never seen it, what does it mean? (Channel in question is Discovery Channel)

 

EDIT: Found (TR 101 162) what it meant (0x53415053 == Scientific Atlanta), but I still don't understand what it is doing there?

Or "Simply Annoying PMT String":idiot:

 

Joking asside, it can mean everything. maybe it's a flag that this stream does contain more (userdefined) informations, like the one from premiere and epg for the options channels...

Thanx for the answers. From the DVB-specs and as Transedit says, it is Private Data Indicator for a Scientific Atlanta device. But Transedit only shows that, not what the data actually is. My provider is currently testing with a Scientific Atlanta platform (HDTV PVR VOD CI+), but I was wondering what kind of information they were actually sending to those devices.

 

Raw capture for those interested:
