Nowadays, Blu-ray has been very popular among people who like to enjoy movies at home. Movies in Blu-ray Discs have better quality in both visual effect and sound effect, and can bring better watching experience to us, and that’s why more and more people prefer Blu-ray over DVD, when DVDs can only offer movies in limited quality. However, we all know how to play a Blu-ray disc, which is as easy as playing a DVD disc, but not many people know very much about blu-ray folders. It’s okay that you don’t know about it if you only need to play Blu-ray discs, but when you find yourself dealing with a Blu-ray folder on your PC, or you are trying to burn a Blu-ray disc yourself, you will need to know something about Blu-ray discs. We have introduced DVD folder structure in the pasy, but what is Blu-ray folder structure? DO we need a Blu-ray folder player? How to play Blu-ray folder on PC? And how to create a Blu-ray folder? This article will soon help you find out.
Part 1: What is a Blu-ray folder structure
A Blu-ray folder consists of a certain structure, that means as long as a folder is a Blu-ray folder, same kind of files or folders can be find in the folder. But what does a Blu-ray folder look like? What is in a Blu-ray folder? Here I’ll introduce briefly for you:
AACS: A directory file. It contains disc level content certificates and media key block data.
BDMV: A directory file. It contains basically all the meaningful content of the disc.
AUXDATA: A directory containing assorted disc-specific metadata.
BACKUP: A directory containing subdirs with backup copies of certain small content. Like .BUP files on DVDs.
BDJO: A directory containing BD-J objects, on discs that use BD-J.
CLIPINF: A directory containing metadata files for the M2TS streams in the STREAM subdir.
JAR: A directory containing JAR (Java archive) files other than the BD-J content. (JAR is basically ZIP with some extra metadata.)
META: A directory containing subdirectories with a metadata XML file, and sometimes thumbnail images, depending on who did the authoring.
PLAYLIST: A directory containing binary playlist files, which describe the playback program chains. Some studios use playlists to implement seamless branching (Disney loves to do this, especially with their animated movies, subbing in language-specific segments for opening titles, credits, etc.).
STREAM: A directory containing the actual audio/video streams, in MPEG-2 transport stream format.
index.bdmv: A metadata file containing an index of the titles.
MovieObject.bdmv: Some sort of object metadata file describing the movie(s) on the disc.
BDSVM: A directory, contains BD+ virtual machine metadata. (BD+ is an additional content security mechanism, favored largely by Fox, which runs an abstract virtual machine to transform stream data at runtime to make the video watchable.)
CERTIFICATE: A directory, contains security certificates that the application(s) on the disc use, including occasionally revocation lists and such.
