The Secret of the Blu-Ray-Region Codes
Hello,
I would like the know more about the structure of Blu-ray Region codes. Here is what I found about DVD-Region codes: In usual DVDs (not RCE), the Region code is stored in the file "VIDEO_TS.IFO" (table "VMGM_MAT"), byte offset 35 decimal (23 hex). A "real" region free (for "pseudo-region-free," see below) or an RCE-protected DVD has the value 0 /00. Here are the values of the Regions (decimal / hexadecimal) : "Pseudo-region-free" (Regions 1-6 are supported, but Region 7 and / or Region 8 are not): R1-R6: 192 / C0 R1-R7: 128 / 80 R1-R6 + R8: 64 / 40 Regions: R1: 254 / FE R2: 253 / FD R3: 251 / FB R4: 247 / F7 R5: 239 / EF R6: 223 / DF R7: 191 / BF R8: 127 / 7F DVDs made for more than one Region have other values, e.g. a DVD for Regions 1 and 4 has 246 / F6, one for 2 and 4 has 245 / F5, one for 2 and 5 has 237 / ED. The RCE protection can be hidden in all .IFO files. It is in one or several PGC's as PRE-command. One must search in the Title-PGC's and Menu-PGC's of the .IFO files the command 'Set GPreg<n> mov <Player Region Code>' and replace the expression <Player Region Code> by the number of the Region for which the DVD is made, e.g. for a DVD for Region 1, the modified command would be: 'Set GPreg<n> mov <1>' Sometimes additional modifications are necessary. But where and how are Blu-ray-Region codes saved, and what are the values? There are, fortunately, much fewer combinations possible than in the case of DVD Regions (ABC [= region free], A, AB [= BA], AC [= CA], BC [= CB], and C). Perhaps someone could explain it to us. Thank you very much in advance and many greetings, A Pal |

It's not as easy with Bluray. a) the region code(s) are not stored on the disc at all. b) The code in the movieobject.bdmv file does similar checks just like a DVD with the commands in the IFO files. c) many Bluray discs do additional checking in Java code (JAR files).

Help (files needed)
Could somebody send me a complete BD without the movie files?
The most important files: MovieObject.bdmv, index.bdmv, PLAYLIST\*.mpls, CLIPINF\*.clpi, (BDJO\*.*). I would like to continue the developing of this tool, but I'm in Africa and I haven't brought any BD stuff with me. Last edited by Pelican9; 22nd February 2008 at 10:04. |

So you need all files except those with .m2ts extension (stream folder)? I will upload on a filesharing site... Is that ok?
Btw, i have a BD that doesn't have a AUXDATA folder and BDedit can't process it. |

I am already uploading ratatouille, which has a certificate folder, and uses java (BDJO & JAR folders) also. Do you have such BD?

Great job! I have been thinking about trying to reverse engineer the file structure of bdmv, in order to be able to replace original streams by re-encoded ones. I assume that the bdmv's have to be updated in that case. Since you seem to have achieved to know the structure, can you explain to me, what settings are related to the stream and where these information are stored in the bdmv's and in which ones? That would be great!
