Hi,

Does anyone have the mux specifications for TVNZ, Discovery and Kordia for all the regions across NZ? I have Auckland as below picture

I have the frequencies but I specifically need the service ID or SISID as the below picture shows.

Service IDs are the same throughout NZ, so those you see in Auckland will be most of them. There used to be some regional/local channels but I think they have all shut down now except for maybe Wairarapa TV. But if you run analyser software on your local muxes you should be able to find the NIT tables that tell you everthing about the entire network - these are broadcast on each mux on each transmitter, and allow software to find the entire network from just one mux. I normally use the TransEdit GUI program from DVBViewer, but that is pay software:

The free command line programs from TSDuck will also work:

https://tsduck.io/

In Linux, this command will analyze the DVB-T stream from 610 MHz (Maori mux here on Wharite) using DVB-T adapter 17. It will read the stream for 10 seconds before reporting its analysis:

tsp -I dvb \
--adapter 17 \
--frequency 610000000 \
--delivery-system DVB-T \
-P analyze \
-P until --seconds 10 \
-O drop

There are other options you can add after the "analyze" plugin name to get different or more specific analysis of the data. See the TSDuck manual.

Thanks for the info, I ended up finding some more information thanks to ChatGPT 😁

Three separate items places
