I spent some time researching a similar idea I had about using a mpeg TS stream to encapsulate arbitrary data and then use a SDR to broadcast it over regular DVB-t frequencies. I didn’t find a lot of information on how to encode/decode the stream, though. I also haven’t found many technical details on how they are doing it in this case. When I first read the article I was hoping it was an open source project, but alas I can’t find anything about this either. Anyone have any hints/pointers?
