Panasonic today announced development of the Early Window Content Protection (EWCP) system for special purpose Airline DVDs for in-flight entertainment. The technology that is fully compliant with the World Airline Entertainment Association's specification 0598 copy protection standard.
EWCP will give airlines the ability to offer their passengers movies in high quality DVD while assuring movie studios that their content is protected.
The Triple DES [content data] encryption used in EWCP provides highly secure content protection, while its fingerprinting technology provides a cutting-edge traceability tool for tracking pirated content. If someone "burns" an unauthorized copy of any Airline DVD or copies the content to a VHS tape, the fingerprint of the Airline DVD player is embedded in the copy, allowing it to be traced back to the very machine from which it was pirated. |
If pirated content is found, the device key of that particular Airline DVD player is revoked. In addition, the fingerprint of the Airline DVD player is embedded into the baseband video signal during playback, so it does not affect conventional authoring systems.
The Airline DVD format differs from normal DVD discs for consumer use, though an Airline DVD Player may also playback consumer type DVD disc. The World Airline Entertainment Association, joined by content providers, airlines and manufacturers of in-flight entertainment devices, adopted specification 0598 in October 2000.
