Revision as of 04:18, 23 December 2005 by Shaddack (talk | contribs) (moved VEIL to Video Encoded Invisible Light)(diff) ← Previous revision | Latest revision (diff) | Newer revision → (diff)VEIL, standing for Video Encoded Invisible Light, is a technology for encoding digital data in video signal, developed by VEIL Interactive Technologies.
VRAM, the Veil Rights Assertion Mark, is a DRM technology combining VEIL with a broadcast flag. It is also known as CGMS-A plus Veil, and broadcast flag on steroids.
Technology
The technology is based on a steganographically encoded data stream placed into the videosignal.
Use in toys
The technology was developed for transmitting data from the video on screen (originally specifically The Batman (TVB series)) to a line of Batman toys based on the series, supplying them with information about the series and unlocking their hidden capabilities.
For example:
- The Batwave Communicator Handheld Device, when in the line of sight of the TV, will show engine graphics, diag, weapon systems, and enables various games stored in the device.
- Batwave Batman Action Figure will pop wings from its back and light up the emblem on its chest when subjected to the videosignal from the TV.
- Batwave Batmobile with Handheld Device will turn on various LEDs acting as its lights, and "capture" various weapons from the show.
Other toys using this technology are
Other uses
As of December 2005, VEIL was proposed as a DRM tool to counter the analog hole, as a technological measure legally enforced by Digital Content Security Act. In this regard, it is a more fine-grained successor of Macrovision.
VEIL acts together with CGMS-A signal ("broadcast flag") in the vertical blanking interval, where it is used to encode the Rights Assertion Mark (RAM) signal. The CGMS-A can be stripped too easily from the analog signal, therefore the presence of RAM but absence of CGMS-A will tell the copy protection system to deny the copy.
