Blu-ray Disc is supported by the Blu-ray Disc Founders, a group of 13 industry giants in the consumer electronics. Blu-ray Disc holds 25 gigabytes of data or high definition video on a single-layer disc and 50 gigabytes on a dual-layer disc. The current DVD disc holds 4.7 gigabytes on single-layer discs and 8.5 gigabytes on dual-layer discs.
While production cost is extremely important to commercial content providers, of equal importance are compatibility with current DVD media and protection of digital content from piracy. In response to these concerns, while no blue-laser disc will be readable using a red-laser, combined blue/red drives (dual laser diodes) and other devices will be perfectly feasible resulting in backwards compatibility with DVD. Several leading drive manufacturers have already proven this feasibility with drives for consumer products such as video recorders that can read and write both DVD and BD discs.
The Blu-Ray format will also offer a content protection system that includes secure AES 128-bit encryption, enhanced production process control and secure key management in both CE and PC devices.
