DVDフォーラム
In an attempt to avoid a costly format war, the Blu-ray Disc Association and DVD Forum started to negotiate a compromise in early 2005. One of the issues was that Blu-ray's supporters wanted to use a Java-based platform for interactivity (BD-J), while the DVD Forum was promoting Microsoft's "iHD" (which became HDi). A much larger issue, though, was the physical formats of the discs themselves; the Blu-ray Disc Association's member companies did not want to risk losing billions of dollars in royalties as they had done with standard DVD. An agreement seemed close, but negotiations proceeded slowly.
