CGMS-A + V-RAMCGMS-A + V-RAM
Concept present by Warner Bros. on May 7th 2003 If CGMS-A is lost or stripped:
All rights information is lost No indication rights information was ever present
Veil encoded Rights Assertion Mark (V-RAM) adds robustness Signals that rights have been asserted and are
carried in CGSM-A CCI information and, if present, the RC state
Inexpensive, Simple, and Adoptable Licensing Terms

Located in the Visible Portion of the video Validated by 3rd party tests for Visibility and
Robustness Asserts that CCI must be present
For CGMS-A+ CCI is conveyed in the CGMS-A signaling
Links the CCI to the Visible portion of the video
