The solution proposed, as implemented by SVP, meets these goals. It allows any network operator to deliver content in a secure fashion to any SVP-enabled third-party device. With SVP-enabled chips included in each consumer electronics device on a viewer’s home network, the operator can extend access control throughout the home network to all devices — including portable devices — and realize dozens of new business models and program packaging options. This is accomplished at virtually no cost to the operator, since proprietary and conditional access components are required only in one “gateway” STB, not in all of the networked devices. Thus the operators' offerings are securely available on all TVs within a viewer household while deploying or subsidising only one STB per viewer household. Furthermore, SVP protection extends even to content that is archived since the content license defines the access criteria as determined by the network operator. This content license must be archived with the content to allow access, and so the rights that the license encodes are always enforced. Therefore, operators can then allow viewers to record and keep content indefinitely, confident that the content can only be viewed within that viewer’s domain, not recopied and redistributed freely to friends and neighbors.
