Kun BD-ROM på Blu-Ray afspillere?

Hvilken del af "full featured discs" forstår du ikke?

BD-R(E) 3.0 medier er omtalt i den artikel du linker til hvis du skulle være i tvivl. Og de bliver måske lidt dyrere - det er rigtigt.

"You should be able to use either media type for personal content, though there may be some added expense for V3 media since it involves additional complexity in manufacturing." "

Betyder det

1) Jeg kan med frit valg af encodning og authoring software lave alt det BDMV indhold som jeg ønsker uden restriktioner (altså som indtil for et par måneder siden). Det skal blot brændes på specielle og lidt dyrere medier, men jeg har stadig fuld valgfrihed til at vælge brænder software, og anden software i processen.

eller

2) Visse betroede firmaer i Blu-Ray alliancen stiller software til rådighed (dvs. sælger for $$$), som giver mig mulighed for at lave BMDV authoring og brænde visse former for video til disse særlige disce. Visse former for video kunne f.eks. være video, som softwaren kan verificere kommer fra dit videokamera eller anden kilde, som Blu-Ray alliancen ikke frygter er kompromitteret.

Jeg ser frem til svaret.

Umiddelbart lyder specielle AACS-approved medier som noget der er beregnet på Managed Copy, altså muligheden for at lave sikkerhedkopier af en disc. Det bliver naturligvis med AACS eller anden DRM, og ikke samme frihed som hvis man selv stripper AACS og brænder BDMV indholdet til en almindelige BD-R(E) disc.

mhelt skrev: Det har jeg ikke det definitive svar på. Jeg vil forvente at der kræves licensafgifter for at lave software til BDMV authoring (det gør der vel også til DVD og HD-DVD), og derfor forventer jeg ingen ændringer blandt eksisterende leverandører.

Jeg betaler ikke en krone, når jeg laver DVD authoring til privat brug, og det skal jeg heller ikke.

Bare rolig fætter guf....

BD-R/-RE clarification

I've received permission to relay information I received from a CE vendor contact. Some of this slightly contradicts what might be interpreted from what paidgeek has posted; hopefully he'll be able to check with his sources and either confirm what I've posted or either of us will correct as required.

Most current Blu-ray players were shipped with "grace period" support where they weren't required to fully implement AACS on BD-R/-RE discs. In practice what this means on these players is that a BD-R/-RE disc authored with AACS copy protection will not play, while BD-R/-RE discs without AACS copy protection are permitted to play.

Now that the grace period is over players must either fully support AACS from BD-R/-RE, or they may not support BDMV from BD-R/-RE at all. If a player does support AACS from BD-R/-RE it may also support BDMV from non-AACS BD-R/-RE (just as many current players do). Therefore once AACS is fully supported from BD-R/-RE on a given player, the situation will be no different than it is today. Bear in mind that BD-R/-RE support is not required on a Blu-ray Disc player (just as DVD(+/-)R/RW support isn't required on a DVD player). However, I expect most future players will fully support BDMV from BD-R/-RE (with or without AACS). My contact says a firmware upgrade to the players recently released without BDMV BD-R/-RE support is technically possible, but hasn't yet been committed to.

Based on this explanation, I don't believe there is any change in BD-R/-RE media whatsoever, but that this is purely a firmware-related issue. I'm also told there's no obligation for vendors to firmware update players released during the grace period to remove the ability to playback BDMV from BD-R/-RE.

Hope this helps clarify things.

From Paidgeek...

First of all, for those who have been waiting for my follow-up post on this topic, thanks for your patience...

After doing some research, here is what I have been able to clarify.

Blu-ray players first manufactured after Spring of this year are required to support BD-RE v3.0 media (AACS enabled) for playback of recordings where copyright has been asserted (e.g. digital broadcast, managed copy from a Blu-ray movie and similar). These same players may playback authored content from other sources (e.g. home movies) where copyright is not asserted from either BD-RE V3.0 or v2.1 (currently available) media.
An exception was made for players produced before Spring this year such that they may playback authored BD movie content from BD-RE V2.1 media, even though they may not support V3.0 media. The PS3 is already fully compliant with the latest requirements. Other players may or may not be depending on current firmware revisions.

The simple summary is that a consumer can author their own content as they wish using currently available media and play it back on any player that was released prior to Spring 07' as well as any player released since that time, provided that the player can support BD-RE V3.0 media. If a newer player cannot yet support that media type, then BD-RE 2.1 support can be enabled as soon as firmware allows the player to do so.

The specifications are designed not to inconvenience any customer who wants to author content they own.

Ok, men han nævnte faktisk heller ikke BD+ ...
