What documentation did you use to decode hd radio protocol? From what I recall, the formats were all closed in some capacity. Did you reverse engineer it?

- argilo 3y agoMost of the details are available in the specification, which is available here: https://www.nrscstandards.org/standards-and-guidelines/documents/standards/nrsc-5-e/nrsc-5-e.asp https://www.nrscstandards.org/standards-and-guidelines/docum... The missing parts are the audio codec (HDC) and the formats of the various data streams. These have required reverse engineering.
- fooblaster 3y agooh I thought it was closed. Thanks for the pointer.
- fooblaster 3y agoDid you take any notes on the reverse engineering or is your code the documentation?
- argilo 3y agoThe code of nrsc5 (and my transmitter project, https://github.com/argilo/gr-nrsc5 https://github.com/argilo/gr-nrsc5) would be the best source of information for the undocumented parts. I do have some private notes, but the useful information has already gone into the code.
