The % bug is a separate bug to do with a Podcasts's title, I suspect you just need a phone and an MP3 file with a suitably prepared title tag.

The original articles issue is a HD Radio (not DAB) issue to do with images, although it might still be a string parse issue of some kind as it apparently involves "image files with no extension", so presumably filenames? So the RF side can indeed be fun on consumer electronics with modern digital standards. Another example is this claimed RCE over DVB-T: https://twitter.com/David3141593/status/1481963959532011520

Even more sadly, HD Radio is a closed, propretiary format.

Unlike DAB or DAB+ which are open standards with FOSS implementations out there.

HD Radio is closed and proprietary, but there is at least one FOSS receiver out there: https://github.com/theori-io/nrsc5

The protocol itself is actually standardized: https://www.nrscstandards.org/standards-and-guidelines/docum...

It's just the audio codec that's proprietary, but it's basically just a slightly modified version of AAC so it's been decoded.

My understanding was that the implementation was protected by patents. And can one call something a standard if the codec is not documented and needs to be reverse engineered?

Like I said, it's the protocol that is standardized. HD Radio as a whole is not, because of the codec. I think it's absolute BS that the FCC went down the path of a proprietary format, but it's the way things are. And the fact is, we do have at least one FOSS implementation. Since it's not DRM, I believe (but IANAL) that it's perfectly legal to reverse-engineer it.

I doubt Xperi really cares, since HD Radio is a trademark so it's not like you could build, sell and market an "HD Radio" device without licensing from them anyway.
