That Media Realm site is mine. Thanks for linking! RDS is one of those technologies that’s been around for decades and still amazes people. You can buy hardware encoders for about AU$500 these days, and I love introducing stations to it and getting their name and song data to show up on car radios.

This is the blog post[1] from the presenter explaining part of it, with this request in the messages lol:

Thank you for that! I didn’t have the patience for the video, but I found her pen-and-paper decryption in that blog post absolutely lovely.

That “take this post down on the first appearance of any complaint from any party” tact sure changed in a hurry, huh

1.75x, I can't watch any video at any other speed at this point.

Ever tried with Louis Rossmanns or Network Chuck videos? I can't watch them at more than 0.75.
