Panasonic Disk Services is about to introduce DVD-Net that it claims will open up the DVD market for consumer Web transactions.
DVD-Net basically extends DVD-Video to create a hybrid DVD disc that can play in a DVD player or a PC. DVD-Net is an encrypted code that is written into the disk at post production stage. It provides each disk with a unique code and the ability to hide all or portions of data on a disk to be unlocked at a future date.
To unlock the code it needs a key that has to be accessed from a dedicated Web server.
For a commercial transaction, such as unlocking the sequel to a DVD movie on a disc or additional games levels, the consumer enters their credit card details and a unique file is sent over the Internet that unlocks the disk. Panasonic claims that the code is unique to each disc.
