If you can obtain the patent number, then the patent >can be retrieved. The patent _must_ disclose the method used. The patent doesn't include enough information to decode the VCR+ code. It explains how to make/decode _a_ VCR code, but not _the_ VCR+ code. That is, there are a bunch of specific details you need that aren't included. (As an analogy, the RSA patent won't help you decode a particular RSA-encoded message.) Ken Shirriff shirriff@sprite.Berkeley.EDU
