"*Java software support*

    /Main article: BD-J <http://en.wikipedia.org/wiki/BD-J>/

At the 2005 JavaOne <http://en.wikipedia.org/wiki/JavaOne> trade show, 
it was announced that Sun Microsystems 
<http://en.wikipedia.org/wiki/Sun_Microsystems>' Java 
<http://en.wikipedia.org/wiki/Java_platform> cross-platform software 
environment would be included in all Blu-ray Disc players as a mandatory 
part of the standard. Java is used to implement interactive menus on 
Blu-ray Discs, as opposed to the method used on DVD 
<http://en.wikipedia.org/wiki/DVD> video discs, which uses pre-rendered 
MPEG segments and selectable subtitle pictures, which is considerably 
more primitive and less seamless. Java creator James Gosling 
<http://en.wikipedia.org/wiki/James_Gosling>, at the conference, 
suggested that the inclusion of a Java Virtual Machine 
<http://en.wikipedia.org/wiki/Java_Virtual_Machine> as well as network 
connectivity in BD devices will allow updates to Blu-ray Discs via the 
Internet, adding content such as additional subtitle languages and 
promotional features that are not included on the disc at pressing time. 
This Java Version is called BD-J <http://en.wikipedia.org/wiki/BD-J> and 
is a subset of the Globally Executable MHP 
<http://en.wikipedia.org/wiki/Globally_Executable_MHP> (GEM) standard. 
GEM is the world-wide version of the Multimedia Home Platform 
<http://en.wikipedia.org/wiki/Multimedia_Home_Platform> standard."
