Macrovision had announced acquisition of the BD+ technologies that are used in Blu-ray discs and systems to provide a programmable security layer. In reviewing the Cryptography Research Inc. (the creators of BD+/SPDC) web site, I observed that they still had a notice that they owned certain intellectual property relating to SPDC and that interested parties should contact them regarding licensing.
There's nothing wrong with this, but being curious, I asked (via email) Linda Quach, a press relations person, whether Macrovision had indeed acquired all rights, title, and interest in the SPDC/BD+ technologies. Here is the substantive portion of her answer (also via email):
I’ve confirmed with our product management team that we did in fact acquire all rights, title and interest to BD+/SPDC technologies.
We’re working on redesign the content on the Macrovision website to include the BD+ technology, and have asked CRI to continue to host this information for a little while longer while we work on completing our marketing materials, so that anyone interested in finding out more can still have access to this information. We’re working with CRI to ensure that all requests are appropriately handled.
Thanks for the quick response and clarification.
