Abstract: A veneer tie for connecting together an outer wall and an inner wall spaced-apart from the outer wall and defining a cavity therebetween. The veneer tie includes a screw anchor, including an elongate shaft for penetrating into the inner wall, a head formed on one end of the screw anchor and an opening formed in the head. A pintle adapted for engaging and being carried by the head of the screw anchor is provided, and extends outwardly from the head and bridges the cavity between the outer wall and the inner wall. The pintle has at least one hook for extending through the opening formed in the head for connecting the pintle to the screw anchor.

Abstract: Enhanced multimedia content on physical media interacts with the user through a media player and the Internet. Enhanced multimedia utilizes IDs for pieces of content on the media and a media key block. On the enhanced media is a file with a list of URLs. As the enhanced media plays a title requiring an external permission for decryption, the media player accesses the URL for that title and obtains the permission. The permission may be purchased or provided for free. Secure encryption and transmission of permission is accomplished by broadcast encryption using a media key block. Each media has a unique set of keys that allow the media player to process the media key block; however, each media follows a unique path through the media key block. All legitimate media players obtain the media key; circumvention devices cannot decipher the media key block.

Abstract: Protected content distribution is accomplished by a first entity generating a set of asymmetric key pairs, creating a plurality of sets of private keys by selecting a combination of private keys from the set of asymmetric key pairs for each created set, and distributing the sets of private keys to playback devices. A second entity produces protected content including encrypted content and a public key media key block, encrypts a symmetric content key with each public key in the set of asymmetric key pairs to form the public key media key block and encrypts a content title with the symmetric content key to form the encrypted content. A playback device stores one set of private keys, receives the protected content, and decrypts and plays the content title stored in the protected content when a selected one of the set of private keys stored by the playback device successfully decrypts the encrypted symmetric content key stored in the public key media key block of the received protected content.

Abstract: A system and method relating to the production and rendering of pre-recorded audiovisual titles, such as movies or other programs sold on digital versatile discs (DVDs), or other digital storage mediums. In at least one embodiment, the present invention is intended to thwart unauthorized mass distribution of titles. Embodiments of the invention may be used to identify the replicator of any given pre-recorded title, to prevent rendering of a title for which the replicator which produced the title is not identified or not licensed, or where the contents of the title have been tampered with, and to revoke rendering by a player device of one or more unauthorized titles originating from a given replicator.

Abstract: A system for proactive forced renewal of content protection implementations in devices includes a key generation facility to generate and allocate keys for the devices, and to generate revocation data corresponding to revoked keys in response to at least one of a security compromise and on a periodic basis independent of a security compromise; and a device manufacturer to receive the keys from the key generation facility, to embed the keys in content protection implementations for the devices, to distribute the devices, and to renew the content protection implementations in devices after the devices are distributed, in response to at least one of a security compromise and on a periodic basis independent of a security compromise.

Abstract: Detection of watermarks in digital content by a system having a recording device and a playback device may be accomplished in such as a way as to improve the interoperability of the recording and playback devices. In one embodiment, a recording device having a first watermark detection component of a first sensitivity for detecting the watermark in digital content, interoperates with a playback device having a second watermark detection component of a second sensitivity for detecting the watermark in a digital content recording made by the recording device; such that the first sensitivity is more sensitive than the second sensitivity.
