What is VCPS?
VCPS is an innovative technology for encrypting video recordings on DVD+R and DVD+RW discs. Designed to protect recordings of digital broadcast according to the Broadcast Flag rules adopted by the United States Federal Communications Commission (FCC), VCPS also enables direct digital recording of 'copy-once' content from satellite and cable sources.

FAQVCPS Frequently Asked Questions
Q: Is this the only agreement that manufacturers have to sign to implement VCPS in their products?
A: There is only one agreement for the VCPS technology. This agreement covers all types of manufacturing. Note that this agreement does not cover the DVD+RW technology, only the VCPS technology. Access to the DVD+RW technology is obtained through the DVD+RW patent license agreement and the DVD+RW Content Protection Agreement.
Q: Does Philips require a sample for testing?
A: There is no mandatory verification for VCPS, so Philips does not require a sample for testing. Philips offers the service to check your product for specification compliance. Test discs for verifying implementations are available. For further information about verification services and test discs see VCPS verification.
Q: Do we need other specifications, apart from the VCPS specifications, to implement VCPS?
A: The information that is needed to develop products is in the VCPS specification, or in publicly available other standards, except for:
The real device keys and key blocks (the VCPS specifications contain development keys and key blocks that cannot be used in real products). Device keys and key blocks are distributed on CD-R discs. These so-called "Key Distribution Discs" can contain up to 32000 device keys or 100 key blocks. The content of the Key Distribution Discs is described in the VCPS Key Distribution Specification that will be published in Q3 2004.
Two cryptographic constants. These constants are made available only to VCPS licensees who need them for the implementation of their product.
Q: Where can we get sample keys and key blocks?
A: Sample keys and key blocks are provided in Annex C of the VCPS Specifications. A downloadable file with these keys and key blocks can be obtained from the Technology and Architecture page of the VCPS website.
Q: Does a read-only player need to read the ADIP in order to check the DKB consistency?
A: It is not necessary for playback to read data from the ADIP. Players may use the DKB from buffer zone 2 without checking the consistency with information from the ADIP.
Q: Is there any regulation for digital outputs in Japan?
A: Yes, the rules for digital outputs in Japan are described in Operational Guidelines for Digital Terrestrial Television Broadcasting and Operational Guidelines for Digital Satellite Broadcasting, which are available from ARIB. Japan is a country as categorized in A.18.104.22.168 of the Compliance Rules of the VCPS Agreement. See also http://www.arib.or.jp/english/
