Welcome to Blu-ray.org.uk!

A free encyclopedia that covers all things Blu-ray, primarily for enthusiast, homebrew developers, and the curious.

Since the lack of proper documentation and most of the technical specs are confidential, Blu-ray.org.uk was designed to be a comprehensive source of information. Most articles are provided with legitimate sources, and some are from original research.

This wiki will highly focus on the BDMV application format, but other things related to Blu-ray will be added to the wiki as well. Blu-ray's successor, Ultra HD Blu-ray will be on it's own separate category, since it's niche and adoption is slow, while BD is more widely adopted.

This wiki is divided into six sections:

Video Codecs

Audio Codecs

Graphics Formats

So far, there are over 50 pages in the BDWiki. We would appreciate any knowledge you can contribute, for that is what the Wiki concept is all about. See the About page for more information
