HD-DVD or BluRay?

[GooseGaws]

@whyser:

That press release relates to BD-R recordable discs; these are not the same as the commercially released BD-ROM discs.

From the first:

"BD-Java is a programming language. The benefit is that it's very flexible. The drawback is that you may need 100 lines of BD-Java code. HDi is a relatively compact piece of code; one command can cover quite a bit of interactivity.

BD-Java is also more complex, so the possibility of errors is greater. And when BD players are put out, [there's the question of whether] they all support the scenarios as coded up from the low level. [Some of the early problems with BD-Java discs] were in part due to the complexity that BD-Java brings. From our point of view, HDi offers all of the flexibility we need, in practice, and it does so in a more simplified way and in a way that we feel leads to better compatibility, better reliability, and lower costs. "

From the second:

"Engineers who’ve worked with both formats say Blu-ray is a pig to program. While extremely flexible, its programming language, BD-Java, requires lots of low-level code for even the simplest of instructions. The highly skilled programmers needed to do the job don’t exactly grow on trees. And because of the program’s complexity, even the best produce their share of bug-ridden software. 

By comparison, writing software for HD DVD using Microsoft’s HDi interactive technology is a doddle—with one simple command doing the task of scores of lines of BD-Java. More importantly, HDi is the key to HD DVD’s better navigation around menus, and its instinctive ability to interact with the outside world.

Thanks to the internet connection built into all HD DVD players, Toshiba machines allow users to do all sorts of nifty things—like re-edit films, participate in online polls and download trailers. Increasingly, it’s beginning to look as though, after the initial attraction of high-definition’s much sharper picture, interactivity is going to be the deciding factor that determines the outcome of the current format war."
