Which descriptors contain the programme titles and summaries?

[jimbo2018]

Hi. I checked the programme titles and summaries PIDs but I just got code rather than understandable words.

Do I assume this data is in all the tables on these PIDs or on only certain ones?

PIDs I checked

Headers 0x30, to 0x37 inclusive
Summaries 0x40 to 0x47 inclusive

What I am looking for is the actual channel names that appear on the EIT after the summary. In descriptor 0x50 it says for example 'Vidro - BBC ONE London' etc. But these only appear on the actual transponders.

Which descriptor do these appear in on 12.778V?

Also where is the NIT data and EPG numbers for Sky DE (Sky Deutschland)? I cannot find anything in the SI data.

Thanks in advance
