Navigation Commands



This is the list of all Navigation Commands for programming BDMV applications in HDMV mode (also BD-J mode). It's a neutral low-level programming language somewhat "similar" to assembly, that is used to control navigation and menu graphics. The code is stored and compiled into a object code file called a Movie Object. In BD-J mode, an Xlet can be programmed to comtrol these commands. Two examples are provided, one written in Scenarist's syntax and BDedit's syntax.
