You might be sad to hear that the latest standard of over the air (antenna) TV utilizes ATSC 3 audio, requiring tuners to pay 70 licensing fees so you'll have s

  > utilizes ATSC 3 audio There is no such thing as ATSC 3 audio. ATSC is the transmission standard, either ATSC 1 (basically everywhere, 1080p) or ATSC 3 in some cities ("Next-Gen TV", 4K). ATSC 1 uses Dolby Digital AC-3, ATSC 3 uses Dolby AC-4 which is otherwise quite rare. Also, that's a very light example. Look into the patent situation for H.264 / AVC, H.265 / HEVC. They are Open Standards (you can download the documentation right now), but they are patent minefields to implement, with dozens of companies and hundreds, if not thousands of patents. Also, to reply to the comment above you: > If the fee is to one company, it is usually an industry non-profit (HDMI, Bluetooth) that doesn't itself have a stake in the outcome. If it's a pool of companies they also have to hash things out amongst themselves and no one company will have control over another. What? HDMI is not an open standard - you need to pay to get the documentation, pass certification, and pay a royalty fee per device (about 5-15 cents per connector). You also need to license the logo because HDMI is actually a brand. Sure, anyone can get HDMI, but it sure ain't open. And if it's a TV or a monitor, better license HDCP separately. Also, as for Bluetooth... that was a patent minefield for decades.
