Blu-Disc Studio UHD

[DJBrunoLima]

You can use the next PSRs:

Code: Select all

PSR25: Player UHD/HDR Capability
  bit 0: BD-J conversion from sRGB 8-bits to BDMV HDR
  bit 1: Dolby Vision playback
  bit 2: Philips HDR playback
  bit 3: HDR-to-SDR video conversion by Philips HDR
  bit 4: HDR-to-SDR conversion by Colour Remapping Information

PSR26: Display UHD/HDR Capability
  bit 0: 3840x2160 video signal input capable display
  bit 1: BDMV HDR video signal input capable display
  bit 2: Dolby Vision video signal input capable display
  bit 3: Philips HDR video signal input capable display

Alexey, what option and command would you recommend based on the image I sent you?

I am about to close a contract with a commercial company, they asked me which program I would recommend using to work with them and I mentioned BDS UHD, they asked me if I had the knowledge and knowledge to use it, I said the basics, so I want to ask you these questions.

Thank you!

You need to check the appropriate PSR register and play the appropriate movie.

The problem here is that from my experience it behaves slightly odd.

HDR supported by player means that bits 1 and/or 2 should be enabled. Thus you should check PSR25 against 00110b = 6.
HDR supported by display means that bits 1 and/or 2 and/or 3 should be enabled. Thus you should check PSR26 against 1110b = 14.

DV supported by player means that bit 1 should be enabled. Thus you should check PSR25 against 00010b = 2.
DV supported by display means that bit 2 should be enabled. Thus you should check PSR26 against 0100b = 4.

There are 2 functions that I planned to add to the manager, but the only customer who checked them said that they complains on a lot of situations (basically always says that not supported).

Code: Select all

public boolean isHDRsupported() {
  int player = getPSR(25) & 6;
  int tv = getPSR(26) & 14;
  return (player > 0) && (tv > 0);
}

public boolean isDVsupported() {
  int player = getPSR(25) & 2;
  int tv = getPSR(26) & 4;
  return (player > 0) && (tv > 0);
}

Finally they added their own simple check in the BDMV part.

Hi Alexey,

I have a quick question about Blu-Disc Studio UHD. I already use Blu-Disc Studio MX Pro and I’m confident with the interface. Does the UHD version use the same interface or will I need to learn the software anew?

Also, having read this thread, am I right in thinking I can purchase this software at a discount as I’m already a BLU-Disc user?

Thank you,

Alan

Hi Alan,
Yes, it is the same app, it just has some additional features/options that are UHD specific.
Yes, there is a discount for existing users.

[AlanBell1975]

As always Alexey, thanks for your prompt response.

I assume you can export as BDMV and BDCMF? If I was to make a check-disc would I need to burn to a BD-R XL disc?

[Alexey Kolesnikov]

Unfortunately, UHDCMF module sells separately for BDS UHD (write an email to get a price with a discount). But you still can use BDCMF from BDS MX Pro.

Most players block playback of discs larger than 50 GB. Some block any media larger than 50 GB, some block depending on the data burned (starting with 66), some allow playback (ignoring this BDA requirement).

[AlanBell1975]

Sorry for my ignorance Alexey,

How is a user able to create a check-disc, prior to replication, with all these playback issues?

Alan.

[Alexey Kolesnikov]

These are not issues. BDA did this intentionally - anti-piracy.
OPPO allowed to play, but it was sold and now it is a new brand (I don't remember the name).
You can google it - there were discussions on forums, like this one https://forum.blu-ray.com/showthread.php?p=22814143

Big studios as far as I know can get players without these limitations.

[AlanBell1975]

Okay, thanks for the information, Alexey.

I'll do some research.

Alan.
