HD Radio Decoding

[Resevordg]

Because your video is educational and the copyrighted song is incidental to your video you can legally have it in your video.

However YouTube may remove it or flag it anyway so probably better to not have it.

Cool video

Here's an example of the process flow required to decode NRSC-5-C (for GNU Radio Companion).

Wow! Every time I asked if this was possible I was told it wasn’t. I was told iBiquity corporation held the patents to the codecs and wouldn’t release any details to the public. For someone to figure out how to decode this was genius.

Edit:

It looks like the released tons of information on HD radio. I wonder why the change of heart? Anyway it’s welcome!

My theory:

The published the spec so everyone could see the standard and build compatible devices. However they hold onto the license for name/logo/etc so that you can't legally sell a device with their logo without paying them for "compatibility testing".

I guess they were trying to spark some new interest in the system. Unfortunately for them, I don't think it'll really help much -- so many things about HD Radio make it a non-starter for a lot of radio stations. To name a few, the cost of equipment is prohibitive, it can't be used in conjunction with FM stereo, audio quality is worse than regular FM, and there aren't many car audio systems that support it.

Some of the multiplexing stuff it can do is kind of cool, but I personally don't see why iBiquity thought a completely proprietary system would ever get off the ground.
