I feel like we need an open source DVD and CD so that they will survive for the long term. Streaming is nice but I don't want to pay monthly fees forever just to hear the music I like.

DVD and CD are completely documented formats, the DRM has been cracked, and the patents are expired. Blu-ray patents are about to expire.

The issue with blu-ray is (and will likely always be) the decryption keys, which are copyrighted and cannot be distributed legally.

▲

wmf 2 hours ago | parent [-]

Encryption keys, being purely random, are not copyrightable. (In light of recent events, this raises the question of artisanal human-created keys.) Distributing keys probably violates DMCA section 1201 though.

		BD+ and AACS are literally that though, that’s why VLC can’t play blu-rays. > NB: Most commercial Blu-Ray are protected by AACS or BD+ technologies and this library is not enough to playback those discs. https://www.videolan.org/developers/libbluray.html clicking into the libaacs and libbd+ yields: > NB: this project doesn't offer any key or certificate that could be used to decode encrypted copyrighted material.

		Spotify's offline playback DRM hinges on a HMAC key that's a human-readable phrase, based on a certain lyric. I'm curious whether it's just a fun easter egg, or if there's some kind of legal basis for the choice. See also https://theapplewiki.com/wiki/Dont_Steal_Mac_OS.kext

FWIW me reading the headline alone was enough to help justify a NAS purchase with my not-as-tech-inclined wife so we can just start dumping things there one way or another...

You mean, a jailbroken ps3? :)

PS3 is a great Blu-ray player IMO. Solid console, solid controller, good laser implementation. Just pop it in and it Just Works.

Seeing a native Blu-ray (god I hate typing that out) on my then 1080p Panny Plasma was a sight to behold. The quality was fantastic, incredible detail and color in a dark room. I miss the console, the television, and the couch I sat on. All of that is gone. But I still remember the glory of seeing it for the first time.

PS3 wont do 4k though will it?

▲

No, but I believe there's 4k version of the PS4 that came out towards the end of that console's lifecycle. I'm satisfied with my regular 1080p PS4 though.

It won't play 4K blu-rays, only the PS5 will.

I think at this point it’s called vinyl.

▲

Vinyl is far from open source CD due to limitations of phisical format and the fact that good vinyl contains specifically mastered for vinyl with those limitations taken into account.

You can still easily buy Bluray player and open source your discs with ARM (not CPU/SoCs, different one)

If you're referring to the RIAA equalization curve[1] that is completely open and well defined.

		Like all analog formats, vinyl has a non-linear response. Things like total amplitude and frequency content affect noise and distortion when reproduced. Another factor is that it's a constant angular velocity medium, so the response is different at the beginning than the end. These are factors that a good mastering engineer takes into account. This occurs in the digital world as well. When we went to DVDs, the studios had encoders/authoring engineers, who tweaked compression parameters per scene, as compression is another non-linear process. For example, they might apply a small amount of blur on a dark scene where film grain trips up the compression. Eta: Apple provides the exact pipeline [1] they use for their services so the sound engineer can listen to the output and adjust. [1] https://www.apple.com/apple-music/apple-digital-masters/

I really hope not, there isn't a single redeeming quality to vinyls from any practical point of view.

The big album art?

	▲	satellites 2 hours ago \| parent \| next [-]
		Even the discs themselves can be works of art now. Even though vinyl discs are less practical than CDs they're a subjectively fun art experience.

		I'll give it that, though the size in general is a downside for more people than it is a benefit.

to play a record, i don't need a computer or any electronics created after, say, 1960 or so. that's a nice benefit :)

		Better yet, you don't need any components in the supply chain that weren't well within the means of people 100 years ago. Vinyls and Edison cylinders will outlive every CD ever made.
