I think you DO have a point here.
The new technology, which will rely exclusively on the audible (!) audio signal, might be faced with problems that cannot be solved completely:
- What if a movie starts with silence? What if hundreds of movies start with silence?
- What if a movie contains a famous scene from another movie?
The current system has the advantage that it looks for some form of unique signature in the digital stream - this is a 99.99% secure way to distinguish movies. (there are some snippets that cause my controller to briefly detect a "26 Days..." movie for a fair number of movies while starting).
Once a movie has been detected the code is present and even if you jump within a movie, the sync after the jump is virtually instant. The new controller might need some audible fodder to detect where whithin a movie you are...
On the other hand, getting rid or reducing the need of re-syncs for new disc versions and opening up a whole new world of broadcast and streaming as "D-Box compatible" might be worth the move for D-Box.
