According to NetBlender, iPhone and iPod touch users will be able to control their Blu-ray players using an application called BD Touch. The application will use the network capabilities of Blu-ray hardware and Apple's handheld devices to transfer data, allowing you to do many different things beyond controlling movie playback.
According to NetBlender:
• The iPhone application will be able to interact directly with movies, showing extra information in the iPhone.
• It will also be able to keep a database of your movie collection.
• BD Touch will also be able to get digital copies of the movies inside the Blu-ray disc, presumably already encoded for iPod touch and iPhone playback.
Netblender will release more details on Thursday.
